[1] The disease caused by Asbestos is -
A.
Emphysema
B.
Paralysis
C.
Diarrhoea
D.
Dysentery
Ans:
Emphysema
Explanation :
Emphysema is the common lung disease caused by asbestos. Emphysema is a lung condition in which tiny air sacs in the lungs - alveoli - fill up with air. As the air continues to build up in these sacs, they expand, and may break or become damaged and form scar tissue. The patient becomes progressively short of breath. Emphysema is a type of COPD (chronic obstructive pulmonary disease).

[10] Which of the following is not a component of chlorophyll?
A.
Hydrogen
B.
Magnesium
C.
Carbon
D.
Calcium
Ans:
Calcium
Explanation :
Chlorophyll, a photo-receptive pigment, allows plants to absorb sunlight and synthesize it into carbohydrates and oxygen. The basic formula for photosynthesis takes 6 molecules of carbon dioxide and 6 molecules of water, reacts them in the presence of chlorophyll and sunlight (a catalyst), and converts them into 1 molecule of glucose (C6H12O6) and 6 molecules of oxygen. Chlorophyll is a chlorin pigment, which is structurally similar to and produced through the same metabolic pathway as other porphyrin pigments such as heme. At the center of the chlorin ring is a magnesium ion. The molecular formula of C55H70O6N4 Mg and a structure of (2-formyl)chlorophyll has been deduced based on NMR, optical and mass spectra.
[11] Development of an egg without fertilization is called -
A.
Gametogenesis
B.
Parthenogenesis
C.
Oogenesis
D.
Metamorphosis
Ans:
Parthenogenesis
Explanation :
Parthenogenesis is a form of asexual reproduction in which growth and development of embryos occur without fertilization. In plants, parthenogenesis means development of an embryo from an unfertilized egg cell, and is a component process of apomixis. Parthenogenesis occurs naturally in many plants, some invertebrate animal species (including nematodes, water fleas, some scorpions, aphids, some bees, some Phasmida, and parasitic wasps) and a few vertebrates (such as some fish, amphibians, reptiles, and very rarely birds). This type of reproduction has been induced artificially in a few species including fish and amphibians.
[12] In the process of dialysis, used on patients with affected kidneys, the phenomenon involved is -
A.
Diffusion
B.
Absorption
C.
Osmosis
D.
Electrophoresis
Ans:
Osmosis
Explanation :
Dialysis is the artificial process of getting rid of waste (diffusion) and unwanted water (ultrafiltration) from the blood. This process is naturally done by our kidneys. It is the artificial replacement for lost kidney function (renal replacement therapy). The elimination of unwanted water (ultrafiltration) occurs through osmosis - as the dialysis solution has a high concentration of glucose, it results in osmotic pressure which causes the fluid to move from the blood into the dialysate. Consequently, a larger quantity of fluid is drained than introduced.
[13] The language used in writing the scientific name of animals is -
A.
French
B.
Latin
C.
German
D.
Dutch
Ans:
Latin
Explanation :
Throughout most of the history of Western science, all scientific literature was written in Latin. Only recently has it been written in spoken languages like English. The use of Latin names has remained so that scientists that speak different languages can understand what they are talking about. Another reason is that many plants and animals have common names that differ by region. Having a Latin name avoids confusion among scientists.
[14] Ripe grapes contain -
A.
Fructose
B.
Sucrose
C.
Galactose
D.
Glucose
Ans:
Fructose
Explanation :
Fully mature or ripe grapes contain about an equal concentration of glucose and fructose, which are the simple sugars yeast ferment to form alcohol and carbon dioxide. Ripe grapes contain ~ 20% of glucose. During ripening the sucrose molecules are hydrolyzed (inverted) by the enzyme invertase into glucose and fructose. By the time of harvest, between 15-25% of the grape will be composed of simple sugars. Both glucose and fructose are six-carbon sugars but three, four, five and seven-carbon sugars are also present in the grape. At time of harvest, there is usually an equal amount of glucose and fructose molecules in the grape; however, as the grape over ripens the level of fructose will become higher.

Therefore virus collections are indispensable instruments in the development of a vaccine. Versatility is distinctive abilities and skills in productively managing a variety of situations. Adaptability is the amount of flexibility and versatility an individual has developed to respond to changing interpersonal situations and environmental requirements.
[16] According to WHO, the bird flu virus cannot be transmitted through food cooked beyond -
A.
60 degrees celsius
B.
70 degrees celsius
C.
90 degrees celsius
D.
100 degrees celsius
Ans:
70 degrees celsius
Explanation :
Outbreaks by the highly pathogenic H5N1 avian influenza (bird flu) virus in poultry have raised concerns about the source of infection and the risk to humans from various exposures. The H5N1 virus is sensitive to heat. Normal temperatures used for cooking (70°C in all parts of the food) will kill the virus. Consumers need to be sure that all parts of the poultry are fully cooked (no pink parts) and that eggs, too, are properly cooked.
[17] The number of chambers in a human heart is -
A.
Four
B.
Two
C.
Three
D.
Five
Ans:
Four
Explanation :
The human heart has four chambers, two superior atria and two inferior ventricles. The atria are the receiving chambers and the ventricles are the discharging chambers. The pathway of blood through the human heart consists of a pulmonary circuit and a systemic circuit. Deoxygenated blood flows through the heart in one direction, entering through the superior vena cava into the right atrium and is pumped through the tricuspid valve into the right ventricle before being pumped out through the pulmonary valve to the pulmonary arteries into the lungs.
[18] Human cloning is permitted in Britain for the purpose of -
A.
Reproduction
B.
Research
C.
Therapeutics
D.
Genetics
Ans:
Therapeutics
Explanation :
Human cloning is the creation of a genetically identical copy of a human. It does not refer to monozygotic multiple births or the reproduction of humans/animals cells or tissue. There are two commonly discussed types of human cloning: therapeutic cloning and reproductive cloning. Therapeutic cloning involves cloning cells from an adult for use in medicine and transplants, and is an active area of research. Reproductive cloning would involve making cloned humans, for couples wanting to have a child, but cannot naturally.
[19] Pick out the viral disease among the following -
A.
Hepatitis
B.
Meningitis
C.
Arthritis
D.
Nephritis
Ans:
Hepatitis
Explanation :
Hepatitis is a medical condition defined by the inflammation of the liver and characterized by the presence of inflammatory cells in the tissue of the organ. The condition can be self-limiting (healing on its own) or can progress to fibrosis (scarring) and cirrhosis. A group of viruses known as the hepatitis viruses cause most cases of hepatitis worldwide, but hepatitis can also be caused by toxins (notably alcohol, certain medications, some industrial organic solvents and plants), other infections and autoimmune diseases.
[20] EEG records the activity of -
A.
heart
B.
lungs
C.
brain
D.
muscles
Ans:
brain
Explanation :
Electroencephalography (EEG) is the recording of electrical activity along the scalp. EEG measures voltage fluctuations resulting from ionic current flows within the neurons of the brain. In clinical contexts, EEG refers to the recording of the brain’s spontaneous electrical activity over a short period of time, usually 20–40 minutes, as recorded from multiple electrodes placed on the scalp. Diagnostic applications generally focus on the spectral content of EEG, that is, the type of neural oscillations that can be observed in EEG signals. In neurology, the main diagnostic application of EEG is in the case of epilepsy.
[21] The colour of cow's milk is slightly yellow due to the presence of -
A.
Xanthophyll
B.
Riboflavin
C.
Ribulose
D.
Carotene
Ans:
Carotene
Explanation :
Yellow milk is commonly related to the diet that that cow is on. Grass is the most common diet that will turn milk (and fat) yellow, due to a compound in the grass that makes it green called Carotene. Carotene is a kind of plant-steriod that makes plants the vibrant colours they are, and this carries through the body of the grazer that eats these plants. Carotene mostly affects the colour of fat. Since milk is comprised of around 3.5% milk fat, a dairy cow that is grass-fed tends to produce yellow milk, over a dairy cow that is not grass-fed and fed primarily a mix of hay, silage and grain.

The basic formula for photosynthesis takes 6 molecules of carbon dioxide and 6 molecules of water, reacts them in the presence of chlorophyll and sunlight (a catalyst), and converts them into 1 molecule of glucose (C6H12O6) and 6 molecules of oxygen. Chlorophyll is a chlorin pigment, which is structurally similar to and produced through the same metabolic pathway as other porphyrin pigments such as heme. At the center of the chlorin ring is a magnesium ion. The molecular formula of C55H70O6N4 Mg and a structure of (2-formyl)chlorophyll has been deduced based on NMR, optical and mass spectra.
[11] Development of an egg without fertilization is called -
A.
Gametogenesis
B.
Parthenogenesis
C.
Oogenesis
D.
Metamorphosis
Ans:
Parthenogenesis
Explanation :
Parthenogenesis is a form of asexual reproduction in which growth and development of embryos occur without fertilization. In plants, parthenogenesis means development of an embryo from an unfertilized egg cell, and is a component process of apomixis. Parthenogenesis occurs naturally in many plants, some invertebrate animal species (including nematodes, water fleas, some scorpions, aphids, some bees, some Phasmida, and parasitic wasps) and a few vertebrates (such as some fish, amphibians, reptiles, and very rarely birds). This type of reproduction has been induced artificially in a few species including fish and amphibians.
[12] In the process of dialysis, used on patients with affected kidneys, the phenomenon involved is -
A.
Diffusion
B.
Absorption
C.
Osmosis
D.
Electrophoresis
Ans:
Osmosis
Explanation :
Dialysis is the artificial process of getting rid of waste (diffusion) and unwanted water (ultrafiltration) from the blood. This process is naturally done by our kidneys. It is the artificial replacement for lost kidney function (renal replacement therapy). The elimination of unwanted water (ultrafiltration) occurs through osmosis - as the dialysis solution has a high concentration of glucose, it results in osmotic pressure which causes the fluid to move from the blood into the dialysate. Consequently, a larger quantity of fluid is drained than introduced.
[13] The language used in writing the scientific name of animals is -
A.
French
B.
Latin
C.
German
D.
Dutch
Ans:
Latin
Explanation :
Throughout most of the history of Western science, all scientific literature was written in Latin. Only recently has it been written in spoken languages like English. The use of Latin names has remained so that scientists that speak different languages can understand what they are talking about. Another reason is that many plants and animals have common names that differ by region. Having a Latin name avoids confusion among scientists.
[14] Ripe grapes contain -
A.
Fructose
B.
Sucrose
C.
Galactose
D.
Glucose
Ans:
Fructose
Explanation :
Fully mature or ripe grapes contain about an equal concentration of glucose and fructose, which are the simple sugars yeast ferment to form alcohol and carbon dioxide. Ripe grapes contain ~ 20% of glucose. During ripening the sucrose molecules are hydrolyzed (inverted) by the enzyme invertase into glucose and fructose. By the time of harvest, between 15-25% of the grape will be composed of simple sugars. Both glucose and fructose are six-carbon sugars but three, four, five and seven-carbon sugars are also present in the grape. At time of harvest, there is usually an equal amount of glucose and fructose molecules in the grape; however, as the grape over ripens the level of fructose will become higher.
[15] Of all micro-organisms, the most adaptable and versatile are -
A.
Viruses
B.
Bacteria
C.
Algae
D.
Fungi
Ans:
Viruses
Explanation :
The viruses are adaptable and versatile with many variations worldwide and they reproduce within the cells of the immune system of infected people. Therefore virus collections are indispensable instruments in the development of a vaccine. Versatility is distinctive abilities and skills in productively managing a variety of situations. Adaptability is the amount of flexibility and versatility an individual has developed to respond to changing interpersonal situations and environmental requirements.
[16] According to WHO, the bird flu virus cannot be transmitted through food cooked beyond -
A.
60 degrees celsius
B.
70 degrees celsius
C.
90 degrees celsius
D.
100 degrees celsius
Ans:
70 degrees celsius
Explanation :
Outbreaks by the highly pathogenic H5N1 avian influenza (bird flu) virus in poultry have raised concerns about the source of infection and the risk to humans from various exposures. The H5N1 virus is sensitive to heat. Normal temperatures used for cooking (70°C in all parts of the food) will kill the virus. Consumers need to be sure that all parts of the poultry are fully cooked (no pink parts) and that eggs, too, are properly cooked.
[17] The number of chambers in a human heart is -
A.
Four
B.
Two
C.
Three
D.
Five
Ans:
Four
Explanation :
The human heart has four chambers, two superior atria and two inferior ventricles. The atria are the receiving chambers and the ventricles are the discharging chambers. The pathway of blood through the human heart consists of a pulmonary circuit and a systemic circuit. Deoxygenated blood flows through the heart in one direction, entering through the superior vena cava into the right atrium and is pumped through the tricuspid valve into the right ventricle before being pumped out through the pulmonary valve to the pulmonary arteries into the lungs.
[18] Human cloning is permitted in Britain for the purpose of -
A.
Reproduction
B.
Research
C.
Therapeutics
D.
Genetics
Ans:
Therapeutics
Explanation :
Human cloning is the creation of a genetically identical copy of a human. It does not refer to monozygotic multiple births or the reproduction of humans/animals cells or tissue. There are two commonly discussed types of human cloning: therapeutic cloning and reproductive cloning. Therapeutic cloning involves cloning cells from an adult for use in medicine and transplants, and is an active area of research. Reproductive cloning would involve making cloned humans, for couples wanting to have a child, but cannot naturally.
[19] Pick out the viral disease among the following -
A.
Hepatitis
B.
Meningitis
C.
Arthritis
D.
Nephritis
Ans:
Hepatitis
Explanation :
Hepatitis is a medical condition defined by the inflammation of the liver and characterized by the presence of inflammatory cells in the tissue of the organ. The condition can be self-limiting (healing on its own) or can progress to fibrosis (scarring) and cirrhosis. A group of viruses known as the hepatitis viruses cause most cases of hepatitis worldwide, but hepatitis can also be caused by toxins (notably alcohol, certain medications, some industrial organic solvents and plants), other infections and autoimmune diseases.
[20] EEG records the activity of -
A.
heart
B.
lungs
C.
brain
D.
muscles
Ans:
brain
Explanation :
Electroencephalography (EEG) is the recording of electrical activity along the scalp. EEG measures voltage fluctuations resulting from ionic current flows within the neurons of the brain. In clinical contexts, EEG refers to the recording of the brain’s spontaneous electrical activity over a short period of time, usually 20–40 minutes, as recorded from multiple electrodes placed on the scalp. Diagnostic applications generally focus on the spectral content of EEG, that is, the type of neural oscillations that can be observed in EEG signals. In neurology, the main diagnostic application of EEG is in the case of epilepsy.
[21] The colour of cow's milk is slightly yellow due to the presence of -
A.
Xanthophyll
B.
Riboflavin
C.
Ribulose
D.
Carotene
Ans:
Carotene
Explanation :
Yellow milk is commonly related to the diet that that cow is on. Grass is the most common diet that will turn milk (and fat) yellow, due to a compound in the grass that makes it green called Carotene. Carotene is a kind of plant-steriod that makes plants the vibrant colours they are, and this carries through the body of the grazer that eats these plants. Carotene mostly affects the colour of fat. Since milk is comprised of around 3.5% milk fat, a dairy cow that is grass-fed tends to produce yellow milk, over a dairy cow that is not grass-fed and fed primarily a mix of hay, silage and grain.
[22] Antibodies are mainly synthesized from -
A.
Megakaryocyte
B.
Monocyte
C.
Lymphocyte
D.

Explanation :
Amino acids are the molecular building blocks of proteins. So proteins are synthesized from them. Essential ami acids are histidine, isoleucine, leucine, methionine, phenyl lanine, threonine, tryptophan, valine, and lysine.
Explanation :
Insulin is a peptide hormone, produced by beta cells of the pancreas, and is central to regulating carbohydrate and fat metabolism in the body. Insulin causes cells in the liver, skeletal muscles, and fat tissue to take up glucose from the blood. In the liver and skeletal muscles, glucose is stored as glycogen, and in adipocytes it is stored as triglycerides.
[6] The ‘Theory of Evolution’ was put forward by -
A.
Louis Pasteur
B.
Aristotle
C.
Gregor Mendel
D.
Charles Darwin
Ans:
Charles Darwin
Explanation :
Charles Darwin had proposed “theory of Evolution”. The theory of evolution came into view by the reawakening of ancient materialistic philosophies and became widespread in the 19th century. This philosophy supposes that matter is absolute and infinite. This materialistic philosophy does not hold anything to be real except the matter, so it tries to explain the universe and nature through purely material factors.

Antibodies are produced by specialized white blood cells called B lymphocytes (or B cells). When an antigen binds to the B-cell surface, it stimulates the B cell to divide and mature into a group of identical cells called a clone.
[23] Penicillin is widely used as -
A.
an antiseptic
B.
a disinfectant
C.
an antibiotic
D.
an insecticide
Ans:
an antibiotic
Explanation :
Penicillin is widely used as an antibiotic. Penicillins are a group of antibacterial drugs that attack a wide range of bacteria. They were the first drugs of this type that doctors used. The discovery and manufacture of penicillins have changed the face of medicine, as these drugs have saved millions of lives.
[24] Antacids are found in medicines that cure -
A.
eyesight
B.
stomach ache
C.
pimpus
D.
headache
Ans:
stomach ache
Explanation :
An antacid is a substance which neutralizes stomach acidity. Antacids are taken by mouth to relieve heartburn, the major symptom of gastro-esophageal reflux disease, or acid indigestion which are a few of the common terms used to describe digestive upset.
[25] Where do plants synthesize protein from?
A.
Fatty Acids
B.
Sugar
C.
Amino Acids
D.
Starch
Ans:
Amino Acids
Explanation :
Amino acids are the molecular building blocks of proteins. So proteins are synthesized from them. Essential ami acids are histidine, isoleucine, leucine, methionine, phenyl lanine, threonine, tryptophan, valine, and lysine.
Explanation :
Fusus vesiculosus is a brown seaweed and is also known as bladderwrack or red algae, according to the National Institutes of Health (NIH). Red marine algae and other seaweeds are common components of Asian diets and are often used in dietary supplements. The high iodine content in red marine algae can lead to hypothyroidism or hyperthyroidism.
[10] Which of the following is not a component of chlorophyll?
A.
Hydrogen
B.
Magnesium
C.
Carbon
D.
Calcium
Ans:
Calcium
Explanation :
Chlorophyll, a photo-receptive pigment, allows plants to absorb sunlight and synthesize it into carbohydrates and oxygen. The basic formula for photosynthesis takes 6 molecules of carbon dioxide and 6 molecules of water, reacts them in the presence of chlorophyll and sunlight (a catalyst), and converts them into 1 molecule of glucose (C6H12O6) and 6 molecules of oxygen. Chlorophyll is a chlorin pigment, which is structurally similar to and produced through the same metabolic pathway as other porphyrin pigments such as heme. At the center of the chlorin ring is a magnesium ion. The molecular formula of C55H70O6N4 Mg and a structure of (2-formyl)chlorophyll has been deduced based on NMR, optical and mass spectra.
[11] Development of an egg without fertilization is called -
A.
Gametogenesis
B.
Parthenogenesis
C.
Oogenesis
D.
Metamorphosis
Ans:
Parthenogenesis
Explanation :
Parthenogenesis is a form of asexual reproduction in which growth and development of embryos occur without fertilization. In plants, parthenogenesis means development of an embryo from an unfertilized egg cell, and is a component process of apomixis. Parthenogenesis occurs naturally in many plants, some invertebrate animal species (including nematodes, water fleas, some scorpions, aphids, some bees, some Phasmida, and parasitic wasps) and a few vertebrates (such as some fish, amphibians, reptiles, and very rarely birds). This type of reproduction has been induced artificially in a few species including fish and amphibians.
[12] In the process of dialysis, used on patients with affected kidneys, the phenomenon involved is -
A.
Diffusion
B.
Absorption
C.
Osmosis
D.
Electrophoresis
Ans:
Osmosis
Explanation :
Dialysis is the artificial process of getting rid of waste (diffusion) and unwanted water (ultrafiltration) from the blood. This process is naturally done by our kidneys. It is the artificial replacement for lost kidney function (renal replacement therapy). The elimination of unwanted water (ultrafiltration) occurs through osmosis - as the dialysis solution has a high concentration of glucose, it results in osmotic pressure which causes the fluid to move from the blood into the dialysate. Consequently, a larger quantity of fluid is drained than introduced.
[13] The language used in writing the scientific name of animals is -
A.
French
B.
Latin
C.
German
D.
Dutch
Ans:
Latin
Explanation :
Throughout most of the history of Western science, all scientific literature was written in Latin. Only recently has it been written in spoken languages like English. The use of Latin names has remained so that scientists that speak different languages can understand what they are talking about. Another reason is that many plants and animals have common names that differ by region. Having a Latin name avoids confusion among scientists.
[14] Ripe grapes contain -
A.
Fructose
B.
Sucrose
C.
Galactose
D.
Glucose
Ans:
Fructose
Explanation :
Fully mature or ripe grapes contain about an equal concentration of glucose and fructose, which are the simple sugars yeast ferment to form alcohol and carbon dioxide. Ripe grapes contain ~ 20% of glucose. During ripening the sucrose molecules are hydrolyzed (inverted) by the enzyme invertase into glucose and fructose. By the time of harvest, between 15-25% of the grape will be composed of simple sugars. Both glucose and fructose are six-carbon sugars but three, four, five and seven-carbon sugars are also present in the grape. At time of harvest, there is usually an equal amount of glucose and fructose molecules in the grape; however, as the grape over ripens the level of fructose will become higher.
[15] Of all micro-organisms, the most adaptable and versatile are -
A.
Viruses
B.
Bacteria
C.
Algae
D.
Fungi
Ans:
Viruses
Explanation :
The viruses are adaptable and versatile with many variations worldwide and they reproduce within the cells of the immune system of infected people. Therefore virus collections are indispensable instruments in the development of a vaccine. Versatility is distinctive abilities and skills in productively managing a variety of situations. Adaptability is the amount of flexibility and versatility an individual has developed to respond to changing interpersonal situations and environmental requirements.
[16] According to WHO, the bird flu virus cannot be transmitted through food cooked beyond -
A.
60 degrees celsius
B.
70 degrees celsius
C.
90 degrees celsius
D.
100 degrees celsius
Ans:
70 degrees celsius
Explanation :
Outbreaks by the highly pathogenic H5N1 avian influenza (bird flu) virus in poultry have raised concerns about the source of infection and the risk to humans from various exposures. The H5N1 virus is sensitive to heat. Normal temperatures used for cooking (70°C in all parts of the food) will kill the virus. Consumers need to be sure that all parts of the poultry are fully cooked (no pink parts) and that eggs, too, are properly cooked.
[17] The number of chambers in a human heart is -
A.
Four
B.
Two
C.
Three
D.
Five
Ans:
Four
Explanation :
The human heart has four chambers, two superior atria and two inferior ventricles. The atria are the receiving chambers and the ventricles are the discharging chambers. The pathway of blood through the human heart consists of a pulmonary circuit and a systemic circuit. Deoxygenated blood flows through the heart in one direction, entering through the superior vena cava into the right atrium and is pumped through the tricuspid valve into the right ventricle before being pumped out through the pulmonary valve to the pulmonary arteries into the lungs.
[18] Human cloning is permitted in Britain for the purpose of -
A.
Reproduction
B.
Research
C.
Therapeutics
D.
Genetics
Ans:
Therapeutics
Explanation :
Human cloning is the creation of a genetically identical copy of a human. It does not refer to monozygotic multiple births or the reproduction of humans/animals cells or tissue. There are two commonly discussed types of human cloning: therapeutic cloning and reproductive cloning. Therapeutic cloning involves cloning cells from an adult for use in medicine and transplants, and is an active area of research. Reproductive cloning would involve making cloned humans, for couples wanting to have a child, but cannot naturally.
[19] Pick out the viral disease among the following -
A.
Hepatitis
B.
Meningitis
C.
Arthritis
D.
Nephritis
Ans:
Hepatitis
Explanation :
Hepatitis is a medical condition defined by the inflammation of the liver and characterized by the presence of inflammatory cells in the tissue of the organ. The condition can be self-limiting (healing on its own) or can progress to fibrosis (scarring) and cirrhosis. A group of viruses known as the hepatitis viruses cause most cases of hepatitis worldwide, but hepatitis can also be caused by toxins (notably alcohol, certain medications, some industrial organic solvents and plants), other infections and autoimmune diseases.
[20] EEG records the activity of -
A.
heart
B.
lungs
C.
brain
D.
muscles
Ans:
brain
Explanation :
Electroencephalography (EEG) is the recording of electrical activity along the scalp. EEG measures voltage fluctuations resulting from ionic current flows within the neurons of the brain. In clinical contexts, EEG refers to the recording of the brain’s spontaneous electrical activity over a short period of time, usually 20–40 minutes, as recorded from multiple electrodes placed on the scalp. Diagnostic applications generally focus on the spectral content of EEG, that is, the type of neural oscillations that can be observed in EEG signals. In neurology, the main diagnostic application of EEG is in the case of epilepsy.
[21] The colour of cow's milk is slightly yellow due to the presence of -
A.
Xanthophyll
B.
Riboflavin
C.
Ribulose
D.
Carotene
Ans:
Carotene
Explanation :
Yellow milk is commonly related to the diet that that cow is on. Grass is the most common diet that will turn milk (and fat) yellow, due to a compound in the grass that makes it green called Carotene. Carotene is a kind of plant-steriod that makes plants the vibrant colours they are, and this carries through the body of the grazer that eats these plants. Carotene mostly affects the colour of fat. Since milk is comprised of around 3.5% milk fat, a dairy cow that is grass-fed tends to produce yellow milk, over a dairy cow that is not grass-fed and fed primarily a mix of hay, silage and grain.

In clinical contexts, EEG refers to the recording of the brain’s spontaneous electrical activity over a short period of time, usually 20–40 minutes, as recorded from multiple electrodes placed on the scalp. Diagnostic applications generally focus on the spectral content of EEG, that is, the type of neural oscillations that can be observed in EEG signals. In neurology, the main diagnostic application of EEG is in the case of epilepsy.
[21] The colour of cow's milk is slightly yellow due to the presence of -
A.
Xanthophyll
B.
Riboflavin
C.
Ribulose
D.
Carotene
Ans:
Carotene
Explanation :
Yellow milk is commonly related to the diet that that cow is on. Grass is the most common diet that will turn milk (and fat) yellow, due to a compound in the grass that makes it green called Carotene. Carotene is a kind of plant-steriod that makes plants the vibrant colours they are, and this carries through the body of the grazer that eats these plants. Carotene mostly affects the colour of fat. Since milk is comprised of around 3.5% milk fat, a dairy cow that is grass-fed tends to produce yellow milk, over a dairy cow that is not grass-fed and fed primarily a mix of hay, silage and grain.
[22] Antibodies are mainly synthesized from -
A.
Megakaryocyte
B.
Monocyte
C.
Lymphocyte
D.
Histiocyte
Ans:
Lymphocyte
Explanation :
Antibodies are produced by specialized white blood cells called B lymphocytes (or B cells). When an antigen binds to the B-cell surface, it stimulates the B cell to divide and mature into a group of identical cells called a clone.
[23] Penicillin is widely used as -
A.
an antiseptic
B.
a disinfectant
C.
an antibiotic
D.
an insecticide
Ans:
an antibiotic
Explanation :
Penicillin is widely used as an antibiotic. Penicillins are a group of antibacterial drugs that attack a wide range of bacteria. They were the first drugs of this type that doctors used. The discovery and manufacture of penicillins have changed the face of medicine, as these drugs have saved millions of lives.
[24] Antacids are found in medicines that cure -
A.
eyesight
B.
stomach ache
C.
pimpus
D.
headache
Ans:
stomach ache
Explanation :
An antacid is a substance which neutralizes stomach acidity. Antacids are taken by mouth to relieve heartburn, the major symptom of gastro-esophageal reflux disease, or acid indigestion which are a few of the common terms used to describe digestive upset.
[25] Where do plants synthesize protein from?
A.
Fatty Acids
B.
Sugar
C.
Amino Acids
D.
Starch
Ans:
Amino Acids
Explanation :
Amino acids are the molecular building blocks of proteins. So proteins are synthesized from them. Essential ami acids are histidine, isoleucine, leucine, methionine, phenyl lanine, threonine, tryptophan, valine, and lysine.
Explanation :
The human heart has four chambers, two superior atria and two inferior ventricles. The atria are the receiving chambers and the ventricles are the discharging chambers. The pathway of blood through the human heart consists of a pulmonary circuit and a systemic circuit. Deoxygenated blood flows through the heart in one direction, entering through the superior vena cava into the right atrium and is pumped through the tricuspid valve into the right ventricle before being pumped out through the pulmonary valve to the pulmonary arteries into the lungs.
[18] Human cloning is permitted in Britain for the purpose of -
A.
Reproduction
B.
Research
C.
Therapeutics
D.
Genetics
Ans:
Therapeutics
Explanation :
Human cloning is the creation of a genetically identical copy of a human. It does not refer to monozygotic multiple births or the reproduction of humans/animals cells or tissue. There are two commonly discussed types of human cloning: therapeutic cloning and reproductive cloning. Therapeutic cloning involves cloning cells from an adult for use in medicine and transplants, and is an active area of research. Reproductive cloning would involve making cloned humans, for couples wanting to have a child, but cannot naturally.
[19] Pick out the viral disease among the following -
A.
Hepatitis
B.
Meningitis
C.
Arthritis
D.
Nephritis
Ans:
Hepatitis
Explanation :
Hepatitis is a medical condition defined by the inflammation of the liver and characterized by the presence of inflammatory cells in the tissue of the organ. The condition can be self-limiting (healing on its own) or can progress to fibrosis (scarring) and cirrhosis. A group of viruses known as the hepatitis viruses cause most cases of hepatitis worldwide, but hepatitis can also be caused by toxins (notably alcohol, certain medications, some industrial organic solvents and plants), other infections and autoimmune diseases.
