[1] Which one of the following is not a true fish?
A.
Starfish
B.
Saw fish
C.
Hammer fish
D.
Sucker fish
Ans:
Starfish
Explanation :
Although sea stars (star fish) live underwater and are commonly called "starfish," they are not fish. They do not have gills, scales, or fins like fish do and they move quite differently from fish. While fish propel themselves with their tails, sea stars have tiny tube feet to help them move along.
[2] Johann Gregor Mendel is famous for propounding -
A.
Theory of mutation
B.
Laws of heredity
C.
Cell theory
D.
Theory of acquired characters
Ans:
Laws of heredity
Explanation :
The Laws of Heredity are few; their implications for life are vast. The simplest genetic characteri stics are those whose presence depends on the genotype at a single locus; i.e., one gene controls the expression of one characteristic. Such characters are known as Mendelian, after their original discoverer, the Austrian botanist Gregor Mendel. Over 10,000 Mendelian characters have been identified in humans. Mendelian laws of inheritance are statements about the way certain characteristics are transmitted from one generation to another in an organism.
[3] Yellow Fever is transmitted by -
A.
Aedes
B.
Anopheles
C.
House-fly
D.
Culex
Ans:
Aedes
Explanation :
Yellow fever (also known as Yellow Jack and Bronze John) is an acute viral hemorrhagic disease. The virus is a 40 to 50 nm enveloped RNA virus with positive sense of the Flaviviridae family. The yellow fever virus is transmitted by the bite of female mosquitoes (the yellow fever mosquito, Aedes aegypti, and other species) and is found in tropical and subtropical areas in South America and Africa, but not in Asia. The only known hosts of the virus are primates and several species of mosquito.
[4] Washing of peeled vegetables removes the vitamin -
A.
A
B.
C
C.
D
D.
E
Ans:
C
Explanation :
B-complex vitamins and vitamin C are watersoluble vitamins that are not stored in the body and must be replaced each day. These vitamins are easily destroyed or washed out during food storage and preparation. Fat-soluble vitamins — vitamins A, D, E and K — dissolve in fat before they are absorbed in the blood stream to carry out their functions. Excesses of these vitamins are stored in the liver.
[5] For the aquatic organisms, the source of food is -

[7] A medicine which promotes the secretion of urine is called -
A.
Adrenaline
B.
Monouretic
C.
Diuretic
D.
Triuretic
Ans:
Diuretic
Explanation :
A diuretic provides a means of forced diuresis which elevates the rate of urination. In medicine, diuretics are used to treat heart failure, liver cirrhosis, hypertension and certain kidney diseases. Some diuretics, such as acetazolamide, help to make the urine more alkaline and are helpful in increasing excretion of substances such as aspirin in cases of overdose or poisoning. Diuretics are often abused by sufferers of eating disorders, especially bulimics, in attempts at weight loss.
[8] The chemicals released by one species of animals in order to attract the other members of the same species are -
A.
Hormones
B.
Nucleic acids
C.
Pheromones
D.
Steroids
Ans:
Pheromones
Explanation :
A pheromone is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting outside the body of the secreting individual to impact the behavior of the receiving individual. There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology. Their use among insects has been particularly well documented. In addition, some vertebrates and plants communicate by using pheromones.

[13] Viruses are -
A.
Cellular
B.
Acellular
C.
Unicellular
D.
Multicellular
Ans:
Acellular
Explanation :
Viruses are acellular, meaning they are biological entities that do not have a cellular structure. They therefore lack most of the components of cells, such as organelles, ribosomes, and the plasma membrane. Viruses are sometimes called virions: a virion is a 'complete' virus free in the environment (not in a host).
[14] Brain of a normal human adult weighs about -
A.
1 lb
B.
2 lb
C.
3 lb
D.
4 lb
Ans:
3 lb
Explanation :
The adult human brain weighs on average about 3 lbs. (1.5 kg) with a volume of around 1130 cubic centimetres (cm3) in women and 1260 cm3 in men, although there is substantial individual variation. Men with the same body height and body surface area as women have on average 100g heavier brains, although these differences do not correlate in any simple way with IQ or other measures of cognitive performance. The human brain has the same general structure as the brains of other mammals, but is larger than any other in relation to body size. Large animals such as whales and elephants have larger brains in absolute terms, but when measured using the encephalization quotient which compensates for body size, the human brain is almost twice as large as the brain of the bottlenose dolphin, and three times as large as the brain of a chimpanzee. Much of the expansion comes from the part of the brain called the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought.
[15] Number of Eyes in an Earthworm is -
A.
one
B.
two
C.

[17] The presence of air cavities is an adaptation of -
A.
Desert plants
B.
Trees
C.
Water plants
D.
Mesophytes
Ans:
Water plants
Explanation :
Totally submerged plants are the true water plants or hydrophytes. Because they are truly aquatic they have the greatest number of adaptations to life in water. Air-filled cavities often extend throughout the leaves and stems of aquatic plants, providing an internal atmosphere.
[18] The vitamin necessary for coagulation of blood is -
A.
vitamin B
B.
vitamin C
C.
vitamin K
D.
vitamin E
Ans:
vitamin K
Explanation :
Vitamin K is a group of structurally similar, fatsoluble vitamins that are needed for the post translational modification of certain proteins required for blood coagulation and in metabolic pathways in bone and other tissue. They are 2-methyl-1,4naphthoquinone (3-)derivatives. This group of vitamins includes two natural vitamers: vitamin K1 and vitamin K2. Vitamin K1, also known as phylloquinone, phytomenadione, or phytonadione, is synthesized by plants, and is found in highest amounts in green leafy vegetables because it is directly involved in photosynthesis. It may be thought of as the “plant form” of vitamin K. It is active in animals since animals can easily convert it to vitamin K2.
[19] Ringworm is a disease caused by -
A.
Fungi
B.
Bacteria
C.
Virus
D.
Flies
Ans:
Fungi
Explanation :
Dermatophytosis or ringworm is a clinical condition caused by fungal infection of the skin in humans, pets such as cats, and domesticated animals such as sheep and cattle. The term “ringworm” is a misnomer, since the condition is caused by fungi of several different species and not by parasitic worms. The fungi that cause parasitic infection (dermatophytes) feed on keratin, the material found in the outer layer of skin, hair, and nails. These fungi thrive on skin that is warm and moist, but may also survive directly on the outsides of hair shafts or in their interiors. In pets, the fungus responsible for the disease survives in skin and on the outer surface of hairs.

[24] Jaundice is caused due to the infection of -
A.
Brain
B.
Liver
C.
Kidney
D.
Spleen
Ans:
Liver
Explanation :
Jaundice is a yellow discoloration of the skin, mucous membranes, and the whites of the eyes caused by increased amounts of bilirubin in the blood. Normally, the liver metabolizes and excretes the bilirubin in the form of bile. However, if there is a disruption in this normal metabolism and/or production of bilirubin, jaundice may result.
[25] Founder of Homeopathy is -
A.
Samuel Hahnemann
B.
Hippocrates
C.
Charaka
D.
Sushrutha
Ans:
Samuel Hahnemann
Explanation :
Homeopathy is a system of alternative medicine originated in 1796 by Samuel Hahnemann, based on his doctrine of similia similibus curentur (“like cures like”), according to which a substance that causes the symptoms of a disease in healthy people will cure that disease in sick people. Homeopathy is a vitalist philosophy that interprets diseases and sickness as caused by disturbances in an immaterial vital force or life force. Disturbances are believed to manifest themselves first in mental symptoms, and eventually progress to physical disease if untreated. Homeopathy rejects germ theory, viewing the presence of pathogens as a symptom, rather than cause, of disease. Hahnemann observed from his experiments with cinchona bark, used as a treatment for malaria, that the effects he experienced from ingesting the bark were similar to the symptoms of malaria. He therefore decided cure proceeds through similarity, and treatments must be able to produce symptoms in healthy individuals similar to those of the disease being treated.

[13] Viruses are -
A.
Cellular
B.
Acellular
C.
Unicellular
D.
Multicellular
Ans:
Acellular
Explanation :
Viruses are acellular, meaning they are biological entities that do not have a cellular structure. They therefore lack most of the components of cells, such as organelles, ribosomes, and the plasma membrane. Viruses are sometimes called virions: a virion is a 'complete' virus free in the environment (not in a host).
[14] Brain of a normal human adult weighs about -
A.
1 lb
B.
2 lb
C.
3 lb
D.
4 lb
Ans:
3 lb
Explanation :
The adult human brain weighs on average about 3 lbs. (1.5 kg) with a volume of around 1130 cubic centimetres (cm3) in women and 1260 cm3 in men, although there is substantial individual variation. Men with the same body height and body surface area as women have on average 100g heavier brains, although these differences do not correlate in any simple way with IQ or other measures of cognitive performance. The human brain has the same general structure as the brains of other mammals, but is larger than any other in relation to body size. Large animals such as whales and elephants have larger brains in absolute terms, but when measured using the encephalization quotient which compensates for body size, the human brain is almost twice as large as the brain of the bottlenose dolphin, and three times as large as the brain of a chimpanzee. Much of the expansion comes from the part of the brain called the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought.
[15] Number of Eyes in an Earthworm is -
A.
one
B.
two
C.

[18] The vitamin necessary for coagulation of blood is -
A.
vitamin B
B.
vitamin C
C.
vitamin K
D.
vitamin E
Ans:
vitamin K
Explanation :
Vitamin K is a group of structurally similar, fatsoluble vitamins that are needed for the post translational modification of certain proteins required for blood coagulation and in metabolic pathways in bone and other tissue. They are 2-methyl-1,4naphthoquinone (3-)derivatives. This group of vitamins includes two natural vitamers: vitamin K1 and vitamin K2. Vitamin K1, also known as phylloquinone, phytomenadione, or phytonadione, is synthesized by plants, and is found in highest amounts in green leafy vegetables because it is directly involved in photosynthesis. It may be thought of as the “plant form” of vitamin K. It is active in animals since animals can easily convert it to vitamin K2.
[19] Ringworm is a disease caused by -
A.
Fungi
B.
Bacteria
C.
Virus
D.
Flies
Ans:
Fungi
Explanation :
Dermatophytosis or ringworm is a clinical condition caused by fungal infection of the skin in humans, pets such as cats, and domesticated animals such as sheep and cattle. The term “ringworm” is a misnomer, since the condition is caused by fungi of several different species and not by parasitic worms. The fungi that cause parasitic infection (dermatophytes) feed on keratin, the material found in the outer layer of skin, hair, and nails. These fungi thrive on skin that is warm and moist, but may also survive directly on the outsides of hair shafts or in their interiors. In pets, the fungus responsible for the disease survives in skin and on the outer surface of hairs.
[20] Which of the following instrument is used to measure the blood-pressure?
A.
Thermometer
B.
ECG
C.
Sphygmomanometer
D.
Stethoscope

[24] Jaundice is caused due to the infection of -
A.
Brain
B.
Liver
C.
Kidney
D.
Spleen
Ans:
Liver
Explanation :
Jaundice is a yellow discoloration of the skin, mucous membranes, and the whites of the eyes caused by increased amounts of bilirubin in the blood. Normally, the liver metabolizes and excretes the bilirubin in the form of bile. However, if there is a disruption in this normal metabolism and/or production of bilirubin, jaundice may result.
[25] Founder of Homeopathy is -
A.
Samuel Hahnemann
B.
Hippocrates
C.
Charaka
D.
Sushrutha
Ans:
Samuel Hahnemann
Explanation :
Homeopathy is a system of alternative medicine originated in 1796 by Samuel Hahnemann, based on his doctrine of similia similibus curentur (“like cures like”), according to which a substance that causes the symptoms of a disease in healthy people will cure that disease in sick people. Homeopathy is a vitalist philosophy that interprets diseases and sickness as caused by disturbances in an immaterial vital force or life force. Disturbances are believed to manifest themselves first in mental symptoms, and eventually progress to physical disease if untreated. Homeopathy rejects germ theory, viewing the presence of pathogens as a symptom, rather than cause, of disease. Hahnemann observed from his experiments with cinchona bark, used as a treatment for malaria, that the effects he experienced from ingesting the bark were similar to the symptoms of malaria. He therefore decided cure proceeds through similarity, and treatments must be able to produce symptoms in healthy individuals similar to those of the disease being treated.

[7] A medicine which promotes the secretion of urine is called -
A.
Adrenaline
B.
Monouretic
C.
Diuretic
D.
Triuretic
Ans:
Diuretic
Explanation :
A diuretic provides a means of forced diuresis which elevates the rate of urination. In medicine, diuretics are used to treat heart failure, liver cirrhosis, hypertension and certain kidney diseases. Some diuretics, such as acetazolamide, help to make the urine more alkaline and are helpful in increasing excretion of substances such as aspirin in cases of overdose or poisoning. Diuretics are often abused by sufferers of eating disorders, especially bulimics, in attempts at weight loss.
[8] The chemicals released by one species of animals in order to attract the other members of the same species are -
A.
Hormones
B.
Nucleic acids
C.
Pheromones
D.
Steroids
Ans:
Pheromones
Explanation :
A pheromone is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting outside the body of the secreting individual to impact the behavior of the receiving individual. There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology. Their use among insects has been particularly well documented. In addition, some vertebrates and plants communicate by using pheromones.

[13] Viruses are -
A.
Cellular
B.
Acellular
C.
Unicellular
D.
Multicellular
Ans:
Acellular
Explanation :
Viruses are acellular, meaning they are biological entities that do not have a cellular structure. They therefore lack most of the components of cells, such as organelles, ribosomes, and the plasma membrane. Viruses are sometimes called virions: a virion is a 'complete' virus free in the environment (not in a host).
[14] Brain of a normal human adult weighs about -
A.
1 lb
B.
2 lb
C.
3 lb
D.
4 lb
Ans:
3 lb
Explanation :
The adult human brain weighs on average about 3 lbs. (1.5 kg) with a volume of around 1130 cubic centimetres (cm3) in women and 1260 cm3 in men, although there is substantial individual variation. Men with the same body height and body surface area as women have on average 100g heavier brains, although these differences do not correlate in any simple way with IQ or other measures of cognitive performance. The human brain has the same general structure as the brains of other mammals, but is larger than any other in relation to body size. Large animals such as whales and elephants have larger brains in absolute terms, but when measured using the encephalization quotient which compensates for body size, the human brain is almost twice as large as the brain of the bottlenose dolphin, and three times as large as the brain of a chimpanzee. Much of the expansion comes from the part of the brain called the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought.
[15] Number of Eyes in an Earthworm is -
A.
one
B.
two
C.
many
D.
no eyes
Ans:
no eyes
Explanation :
Earthworms look like tubes with no designated head or tail. There are approximately 2,700 different types of earthworms living today. They are cold-blooded animals who live in soil.
[16] Accupuncture is -
A.
a disease of heart
B.
servicing of tubes and tyres
C.
a treatment method with needles
D.
a crop culture
Ans:
a treatment method with needles
Explanation :
Acupuncture is an alternative medicine methodology originating in ancient China that treats patients by manipulating thin, solid needles that have been inserted into acupuncture points in the skin. According to Traditional Chinese medicine, stimulating these points can correct imbalances in the flow of qi through channels known as meridians.
[17] The presence of air cavities is an adaptation of -
A.
Desert plants
B.
Trees
C.
Water plants
D.
Mesophytes
Ans:
Water plants
Explanation :
Totally submerged plants are the true water plants or hydrophytes. Because they are truly aquatic they have the greatest number of adaptations to life in water. Air-filled cavities often extend throughout the leaves and stems of aquatic plants, providing an internal atmosphere.
[18] The vitamin necessary for coagulation of blood is -
A.
vitamin B
B.
vitamin C
C.
vitamin K
D.
vitamin E
Ans:
vitamin K
Explanation :
Vitamin K is a group of structurally similar, fatsoluble vitamins that are needed for the post translational modification of certain proteins required for blood coagulation and in metabolic pathways in bone and other tissue. They are 2-methyl-1,4naphthoquinone (3-)derivatives. This group of vitamins includes two natural vitamers: vitamin K1 and vitamin K2. Vitamin K1, also known as phylloquinone, phytomenadione, or phytonadione, is synthesized by plants, and is found in highest amounts in green leafy vegetables because it is directly involved in photosynthesis. It may be thought of as the “plant form” of vitamin K. It is active in animals since animals can easily convert it to vitamin K2.
[19] Ringworm is a disease caused by -
A.
Fungi
B.
Bacteria
C.
Virus
D.
Flies
Ans:
Fungi
Explanation :
Dermatophytosis or ringworm is a clinical condition caused by fungal infection of the skin in humans, pets such as cats, and domesticated animals such as sheep and cattle. The term “ringworm” is a misnomer, since the condition is caused by fungi of several different species and not by parasitic worms. The fungi that cause parasitic infection (dermatophytes) feed on keratin, the material found in the outer layer of skin, hair, and nails. These fungi thrive on skin that is warm and moist, but may also survive directly on the outsides of hair shafts or in their interiors. In pets, the fungus responsible for the disease survives in skin and on the outer surface of hairs.
[20] Which of the following instrument is used to measure the blood-pressure?
A.
Thermometer
B.
ECG
C.
Sphygmomanometer
D.
Stethoscope
Ans:
Sphygmomanometer
Explanation :
Blood pressure is measured by an instrument called as sphygmomanometer. The instrument consists of an inflatable rubber cuff which is applied to the arm. This is connected to mercury column which helps to determine the systolic and diastolic blood pressure.
[21] In which of the following class can we put Adrenaline?
A.
Hormone
B.
Enzyme
C.
Protein
D.
Fat
Ans:
Hormone
Explanation :
Adrenaline, also known as epinephrine, is a hormone, neurotransmitter, and medication. Adrenaline is normally produced by both the adrenal glands and certain neurons.
[22] The anti-malarial drug quinine is made from a plant. The plant is -
A.
Neem
B.
Eucalyptus
C.
Cinnamon
D.
Cinchona
Ans:
Cinchona
Explanation :
Cinchona is a tree. People use the bark to make medicine. Cinchona is used for increasing appetite; promoting the release of digestive juices; and treating bloating, fullness, and other stomach problems. It is also used for blood vessel disorders including hemorrhoids, varicose veins, and leg cramps.
[23] Tuberculosis is transmitted through -
A.
Droplet transmission
B.
Blood transfusion
C.
Contaminated water
D.
Sexual contact

[24] Jaundice is caused due to the infection of -
A.
Brain
B.
Liver
C.
Kidney
D.
Spleen
Ans:
Liver
Explanation :
Jaundice is a yellow discoloration of the skin, mucous membranes, and the whites of the eyes caused by increased amounts of bilirubin in the blood. Normally, the liver metabolizes and excretes the bilirubin in the form of bile. However, if there is a disruption in this normal metabolism and/or production of bilirubin, jaundice may result.
[25] Founder of Homeopathy is -
A.
Samuel Hahnemann
B.
Hippocrates
C.
Charaka
D.
Sushrutha
Ans:
Samuel Hahnemann
Explanation :
Homeopathy is a system of alternative medicine originated in 1796 by Samuel Hahnemann, based on his doctrine of similia similibus curentur (“like cures like”), according to which a substance that causes the symptoms of a disease in healthy people will cure that disease in sick people. Homeopathy is a vitalist philosophy that interprets diseases and sickness as caused by disturbances in an immaterial vital force or life force. Disturbances are believed to manifest themselves first in mental symptoms, and eventually progress to physical disease if untreated. Homeopathy rejects germ theory, viewing the presence of pathogens as a symptom, rather than cause, of disease. Hahnemann observed from his experiments with cinchona bark, used as a treatment for malaria, that the effects he experienced from ingesting the bark were similar to the symptoms of malaria. He therefore decided cure proceeds through similarity, and treatments must be able to produce symptoms in healthy individuals similar to those of the disease being treated.

Blood pressure is measured by an instrument called as sphygmomanometer. The instrument consists of an inflatable rubber cuff which is applied to the arm. This is connected to mercury column which helps to determine the systolic and diastolic blood pressure.
[21] In which of the following class can we put Adrenaline?
A.
Hormone
B.
Enzyme
C.
Protein
D.
Fat
Ans:
Hormone
Explanation :

[22] The anti-malarial drug quinine is made from a plant. The plant is -
A.
Neem
B.
Eucalyptus
C.
Cinnamon
D.
Cinchona
Ans:
Cinchona
Explanation :
Cinchona is a tree. People use the bark to make medicine. Cinchona is used for increasing appetite; promoting the release of digestive juices; and treating bloating, fullness, and other stomach problems. It is also used for blood vessel disorders including hemorrhoids, varicose veins, and leg cramps.
[23] Tuberculosis is transmitted through -
A.
Droplet transmission
B.
Blood transfusion
C.
Contaminated water
D.
Sexual contact
Ans:
Droplet transmission

[24] Jaundice is caused due to the infection of -
A.
Brain
B.
Liver
C.
Kidney
D.
Spleen
Ans:
Liver
Explanation :
Jaundice is a yellow discoloration of the skin, mucous membranes, and the whites of the eyes caused by increased amounts of bilirubin in the blood. Normally, the liver metabolizes and excretes the bilirubin in the form of bile. However, if there is a disruption in this normal metabolism and/or production of bilirubin, jaundice may result.
[25] Founder of Homeopathy is -
A.
Samuel Hahnemann
B.
Hippocrates
C.
Charaka
D.
Sushrutha
Ans:
Samuel Hahnemann
Explanation :
Homeopathy is a system of alternative medicine originated in 1796 by Samuel Hahnemann, based on his doctrine of similia similibus curentur (“like cures like”), according to which a substance that causes the symptoms of a disease in healthy people will cure that disease in sick people. Homeopathy is a vitalist philosophy that interprets diseases and sickness as caused by disturbances in an immaterial vital force or life force. Disturbances are believed to manifest themselves first in mental symptoms, and eventually progress to physical disease if untreated. Homeopathy rejects germ theory, viewing the presence of pathogens as a symptom, rather than cause, of disease. Hahnemann observed from his experiments with cinchona bark, used as a treatment for malaria, that the effects he experienced from ingesting the bark were similar to the symptoms of malaria. He therefore decided cure proceeds through similarity, and treatments must be able to produce symptoms in healthy individuals similar to those of the disease being treated.
Explanation :
Dermatophytosis or ringworm is a clinical condition caused by fungal infection of the skin in humans, pets such as cats, and domesticated animals such as sheep and cattle. The term “ringworm” is a misnomer, since the condition is caused by fungi of several different species and not by parasitic worms. The fungi that cause parasitic infection (dermatophytes) feed on keratin, the material found in the outer layer of skin, hair, and nails. These fungi thrive on skin that is warm and moist, but may also survive directly on the outsides of hair shafts or in their interiors. In pets, the fungus responsible for the disease survives in skin and on the outer surface of hairs.
