Explanation :
Hashish, often known as “hash”, is a cannabis preparation composed of compressed and/or purified preparations of stalked resin glands, called trichomes, collected from the unfertilized buds of the cannabis plant. Hashish is made from cannabinoid-rich glandular hairs known as trichomes, as well as varying amounts of cannabis flower and leaf fragments. The flowers of a mature female plant contain the most trichomes, though trichomes are found on other parts of the plant. Certain strains of cannabis are cultivated specifically for their ability to produce large amounts of trichomes.

Ans:
fertilisation in vitro and then transplantation in the uterus.
Explanation :
In vitro fertilisation is a process by which an egg is fertilised by sperm outside the body: in vitro. IVF is a major treatment for infertility when other methods of assisted reproductive technology have failed. The process involves monitoring a woman's ovulatory process, removing ovum or ova (egg or eggs) from the woman's ovaries and letting sperm fertilize them in a fluid medium in a laboratory. When a woman's natural cycle is monitored to collect a naturally selected ovum (egg) for fertilisation, it is known as natural cycle IVF.
[18] Why radiologists do not take direct X-ray photographs of intestine?
A.
Intestines are affected by direct exposure to X-rays
B.
X-rays can not cross intestine
C.

[23] Heart attack occurs due to :
A.
Bacterial attack on the heart
B.
Stopping of heart beat
C.
Lack of blood supply to the heart itself
D.
Impairment of heart’s working due to unknown reasons
Ans:
Lack of blood supply to the heart itself
Explanation :
A heart attack occurs if the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked. If blood) flow isn't restored quickly, the section of heart muscle begins to die. Heart attacks most often occur as a result of coronary heart disease (CHD), also called coronary artery disease. CHD is a condition in which a waxy substance called plaque (plak) builds up inside the coronary arteries. These arteries supply oxygen-rich blood to the heart.

Ans:
It is an optical instrument used to see inside the alimentary canal
Explanation :
Endoscopymeans looking inside and typically refers to looking inside the body for medical reasons using an endoscope, an instrument used to examine the interior of a hollow organ or cavity of the body. Unlike most other medical imaging devices, endoscopes are inserted directly into the organ. Endoscopy can also refer to using a borescope in technical situations where direct line of-sight observation is not feasible. The following conditions and illnesses are most commonly investigated or diagnosed with an endoscopy: breathing disorders; chronic diarrhea; internal bleeding; irritable bowel syndrome; stomach ulcers, etc.

Ans:
these viruses have no heritable information
Explanation :
DNA is an informational molecule encoding the genetic instructions Along with RNA and proteins, it is one of the three major macromolecules that are essential for all known forms of life. Genetic information is encoded as a sequence of nucleotides (guanine, adenine, thymine, and cytosine) recorded using the letters G, A, T, and C.
Explanation :
Mammals are members of class Mammalia, air-breathing vertebrate animals characterized by the possession of endothermy, hair, three middle ear bones, and mammary glands functional in mothers with young. Most mammals also possess sweat glands and specialized teeth. The largest group of mammals, the placentals, have a placenta which feeds the offspring during gestation. Among the mammals, pigs, hippopotamus, camels, giraffe, deer, antelope, cattle, sheep, goats belong to Order Artiodactyla; Order Cetacea: whales, dolphins and porpoises; etc.

Regulation of blood pH
B.
Removal of metabolic wastes from the body
C.
Production of antibodies
D.
Regulation of osmotic pressures of the blood
Ans:
Production of antibodies
Explanation :
Kidneys are essential in the urinary system and also serve homeostatic functions such as the regulation of electrolytes, maintenance of acid-base balance, and regulation of blood pressure Ma maintaining salt and water balance). They serve the body as a natural filter of the blood, and remove wastes which are diverted to the urinary bladder whereas the antibodies are produced by antigens in the cell.
[11] Which is the effect of antigen in an ill person?

It increases the production of W.B.C.
B.
It increases the production of antibiotics
C.
It increases the production of antiserum against bacteria
D.
It prevents the growth of bacteria
Ans:
It increases the production of antibiotics
Explanation :
Vaccines containing antigens are introduced into the body, stimulating the immune system response by instructing B cells, with assistance from T cells, to produce antibodies. Antibodies are produced to fight the weakened or dead viruses in the vaccine. The immune system prepares to destroy real and stronger vinises in the future. When new antigens enter the body, white blood cells called macrophages engulf them; process the information contained in the antigens, and send it to the T cells so that an immune system response can be mobilized.

D.
Even short exposure of X-rays causes cancer in intestine
Ans:
X-rays are not able to capture clear picture
Explanation :
As the intestine is a soft tissue structure, it is not usually seen on a plain X-ray. By using barium to coat the inner lining of this area the Radiologist can see the bowel clearly on the X-ray screen, and can watch the way it functions during this study. A small lubricated plastic tube will be inserted through your nostril or mouth and down into your stomach by the Doctor or Nurse.
[19] What is an antibiotic?

A chemical compound produced by a living organism that inhibits the growth of other organisms
B.
Acompound synthesised by a living organism that inhibits the growth of microbes
C.
Asynthetic compound inhibiting the growth of other organisms
D.
Asynthetic compound inhibiting the growth of bacteria
Ans:
Asynthetic compound inhibiting the growth of bacteria
Explanation :
Antibiotics, also known as antimicrobial drugs, are drugs that fight infections caused by bacteria. Alexander Fleming discovered the first antibiotic, penicillin, in 1927. The term "antibiotic" originally referred to a natural compound produced by a fungus or another microorganism that kills bacteria which cause disease in humans or animals. Some antibiotics may be synthetic compounds (not produced by microorganisms) that can also kill or inhibit the growth of microbes.

tetanus, diphtheria, measles and rubella
D.
tetanus, diphtheria, small pox and rubella
Ans:
whooping cough, tetanus and diphtheria
Explanation :
Triple Antigen vaccine is a combination of Diphtheria, Tetanus, and Pertussis (whooping cough). The vaccine stimulates the production of antibodies to immunize the body against the causative agents of the three viruses listed above. It is recommended to children older than 2 months of age.
[21] Antidiuretic hormone (ADH) -
A.
inhibits the secretion of growth hormone by the pituitary
B.
inhibits the rate of heart beat
C.
causes the muscular walls of the arterioles to contract that simulates the reabsorption of water from the kidney tubules
D.
causes an increase in the blood pressure

[22] Exobiology deals with the study of -
A.
external characters of living organisms
B.
life on the surface of the earth
C.
life in the outer layers of atmosphere
D.
life in other planets and space
Ans:
life in other planets and space
Explanation :
Exobiology is the branch of science that deals with the possibility and likely nature of life on other planets or in space. The primary goal of exobiological research is to reach a better understanding of the processes leading to the origin evolution and distribution of life on Earth or elsewhere in the universe.
[23] Heart attack occurs due to :
A.
Bacterial attack on the heart
B.
Stopping of heart beat
C.
Lack of blood supply to the heart itself
D.
Impairment of heart’s working due to unknown reasons
Ans:
Lack of blood supply to the heart itself
Explanation :
A heart attack occurs if the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked. If blood) flow isn't restored quickly, the section of heart muscle begins to die. Heart attacks most often occur as a result of coronary heart disease (CHD), also called coronary artery disease. CHD is a condition in which a waxy substance called plaque (plak) builds up inside the coronary arteries. These arteries supply oxygen-rich blood to the heart.
[24] What is an endoscope?
A.
It is an optical instrument used to see inside the alimentary canal
B.
It is a device which is fitted on the chest of the patient to regularize the irregular heart beats
C.
It is an instrument used for examining ear disorders
D.
It is an instrument for recording electrical signals produced by human muscles
Ans:
It is an optical instrument used to see inside the alimentary canal
Explanation :
Endoscopymeans looking inside and typically refers to looking inside the body for medical reasons using an endoscope, an instrument used to examine the interior of a hollow organ or cavity of the body. Unlike most other medical imaging devices, endoscopes are inserted directly into the organ. Endoscopy can also refer to using a borescope in technical situations where direct line of-sight observation is not feasible. The following conditions and illnesses are most commonly investigated or diagnosed with an endoscopy: breathing disorders; chronic diarrhea; internal bleeding; irritable bowel syndrome; stomach ulcers, etc.
[25] Some viruses have RNA but no DNA. This would indicate that -
A.
these viruses cannot replicate
B.
these viruses have no heritable information
C.
RNA transmits the hereditary information in these viruses
D.
their nucleic acids can be crystallised
Ans:
these viruses have no heritable information
Explanation :
DNA is an informational molecule encoding the genetic instructions Along with RNA and proteins, it is one of the three major macromolecules that are essential for all known forms of life. Genetic information is encoded as a sequence of nucleotides (guanine, adenine, thymine, and cytosine) recorded using the letters G, A, T, and C.

[16] Hashish is obtained from a plant. From which part of the plant is it obtained?
A.
Leaves
B.
Stem
C.
Exudate from leaves and female inflorescences.
D.
Exudate from stem and male inflorescences.
Ans:
Exudate from leaves and female inflorescences.
Explanation :
Hashish, often known as “hash”, is a cannabis preparation composed of compressed and/or purified preparations of stalked resin glands, called trichomes, collected from the unfertilized buds of the cannabis plant. Hashish is made from cannabinoid-rich glandular hairs known as trichomes, as well as varying amounts of cannabis flower and leaf fragments. The flowers of a mature female plant contain the most trichomes, though trichomes are found on other parts of the plant. Certain strains of cannabis are cultivated specifically for their ability to produce large amounts of trichomes.
[17] A test tube baby means :
A.
a baby grown in a test tube.
B.
embryo fertilised in uterus and developed in test tube.
C.
embryo fertilised and developed in uterus.
D.
fertilisation in vitro and then transplantation in the uterus.
Ans:
fertilisation in vitro and then transplantation in the uterus.
Explanation :
In vitro fertilisation is a process by which an egg is fertilised by sperm outside the body: in vitro. IVF is a major treatment for infertility when other methods of assisted reproductive technology have failed. The process involves monitoring a woman's ovulatory process, removing ovum or ova (egg or eggs) from the woman's ovaries and letting sperm fertilize them in a fluid medium in a laboratory. When a woman's natural cycle is monitored to collect a naturally selected ovum (egg) for fertilisation, it is known as natural cycle IVF.
