[20] The average heart beat rate per minute in a normal person is -
A.
82
B.
92
C.
72
D.
98
Ans:
72
Explanation :
The average heart rate for adult humans is about 70 to 75 beats per minute in a normal relaxed mode. While we tend to think of the "normal" heart beat rate as being "72 beats per minute", in actuality the heart beat rate is not and should not be constant. In fact, the contemporary understanding is that the degree to which the heart beat varies is a key indicator of health and well being. Conversely, the degree to which it does not vary is a key indicator of health risk. The "72 beats per minute" that we are familiar with is the normal average heart beat rate.
[21] HYV refers to -
A.
Hybrid yielding variety
B.
Human yellow virus
C.
High yielding variety
D.
Human yellow vaccine
Ans:
High yielding variety
Explanation :

Multiple crops can be grown easily. Seeds are mostly flood and drought resistant. Problems of pests and diseases are less. HYV seeds yield more under irrigated conditions. However, the crop demands controlled irrigation. This crop should be irrigated at right time as per the schedule and in right quantity. Most of the HYV seeds are dwarf varieties. They need higher doses of fertilizer.
[22] Among the defects of eye, the shortsightedness is called -
A.
coma
B.
hypermetropia
C.
myopia
D.
astigmatism
Ans:
myopia
Explanation :
Myopia, commonly known as being nearsighted and shortsighted. It is a condition of the eye where the light that comes in does not directly focus on the retina but in front of it. This causes the image that one sees when looking at a distant object to be out of focus but in focus when looking at a close object. Eye care professionals most commonly correct myopia through the use of corrective lenses, such as glasses or contact lenses. It may also be corrected by refractive surgery, though there are cases of associated side effects.
[23] A man with colour blindness will see red as -
A.
Yellow
B.
Blue
C.

Cobalt
Ans:
Cobalt
Explanation :
Vitamin B12 is a "generic descriptor for compounds exhibiting the biologic activity of cyanocobalarnin: the antianemia factor of liver extract that contains cobalt, a cyano group, and coffin in a cobamide structure. Vitamin B12 is vital for the formation of red blood cells, as well as for the proper functioning and health of nerve tissue. If left untreated, vitamin B12 deficiency, also known as B12 deficiency, can lead to anemia, as well as nerve and brain damage, which may eventually become irreversible.
Explanation :
Antigens are the substance that when introduced into the body stimulates the production of an antibody. Antigens include toxins, bacteria, foreign blood cells, and the cells of transplanted organs. Antigens can also react with formed antibodies. Antigen-antibody reactions serve as host defenses against microorganisms and other foreign bodies, or are used in laboratory tests for detecting the presence of either antigen or antibody. The antigen city of a protein is determined by its sequence of amino acids as well as by its conformation.

The femur (pl. femurs or femora), or thigh bone, is the most proximal (closest to the center of the body) bone of the leg in tetrapod vertebrates capable of walking or jumping, such as most land mammals, birds, many reptiles such as lizards, and amphibians such as frogs. In vertebrates with four legs such as dogs and horses, the femur is found only in the rear legs. The femur is the largest bone in the human body. The head of the femur articulates with the acetabulum. By most measures the femur is one of the strongest bones in the body.
[15] Hay fever is a sign of -
A.
malnutrition
B.
allergy
C.
oldage
D.
over work
Ans:
allergy
Explanation :
Hay fever involves an allergic reaction to pollen. A similar reaction occurs with allergy to mold, animal dander, dust, and other allergens that you breathe in. Allergic rhinitis is a group of symptoms affecting the nose. These symptoms occur when you breathe in something you are allergic to, such as dust, dander, insect venom, or pollen. An allergen is something that triggers an allergy. When a person with allergic rhinitis breathes in an allergen such as pollen or dust, the body releases chemicals, including histamine.

[18] Which of the following is NOT one of the important steps in processing tea leaves?
A.
Rolling
B.
Drying
C.
Fermenting
D.
Withering
Ans:
Fermenting
Explanation :
Generally, there are four different tea categories that differ in processing methods. By withering, new picked leaves are thinly spread to dry during this process, Heated air is forced over the leaves if the climate is not suitable. The main goal of this process is to reduce the water content. By the end of withering, the leaves should be pliable enough to be rolled.
[19] Dehydration in human body is caused due to the loss of:
A.
vitamins
B.
salts
C.
hormones
D.
water
Ans:
water
Explanation :
Dehydration is the condition where there is acute shortage of water in our body. This occurs when the amount of water leaving our body is greater than the amount consumed. There are three types of dehydration: hypotonic or hyponatremic (primarily a loss of electrolytes, sodium in particular).
[20] The average heart beat rate per minute in a normal person is -
A.
82
B.
92
C.
72
D.
98
Ans:
72
Explanation :
The average heart rate for adult humans is about 70 to 75 beats per minute in a normal relaxed mode. While we tend to think of the "normal" heart beat rate as being "72 beats per minute", in actuality the heart beat rate is not and should not be constant. In fact, the contemporary understanding is that the degree to which the heart beat varies is a key indicator of health and well being. Conversely, the degree to which it does not vary is a key indicator of health risk. The "72 beats per minute" that we are familiar with is the normal average heart beat rate.
[21] HYV refers to -
A.
Hybrid yielding variety
B.
Human yellow virus
C.
High yielding variety
D.
Human yellow vaccine
Ans:
High yielding variety
Explanation :
High Yielding Variety (HYV) seeds played vital role in the progress of agriculture. They are considered as 'miracle seeds'. HYV seeds give better quality yielding. The maturity time of crop is less. Multiple crops can be grown easily. Seeds are mostly flood and drought resistant. Problems of pests and diseases are less. HYV seeds yield more under irrigated conditions. However, the crop demands controlled irrigation. This crop should be irrigated at right time as per the schedule and in right quantity. Most of the HYV seeds are dwarf varieties. They need higher doses of fertilizer.
[22] Among the defects of eye, the shortsightedness is called -
A.
coma
B.
hypermetropia
C.
myopia
D.
astigmatism
Ans:
myopia
Explanation :
Myopia, commonly known as being nearsighted and shortsighted. It is a condition of the eye where the light that comes in does not directly focus on the retina but in front of it. This causes the image that one sees when looking at a distant object to be out of focus but in focus when looking at a close object. Eye care professionals most commonly correct myopia through the use of corrective lenses, such as glasses or contact lenses. It may also be corrected by refractive surgery, though there are cases of associated side effects.
[23] A man with colour blindness will see red as -
A.
Yellow
B.
Blue
C.
Green
D.
Violet
Ans:
Green
Explanation :
Colour-blindness is the inability to distinguish the differences between certain colours. This condition results from an absence of colour-sensitive pigment in the cone cells of the retina, the nerve layer at the back of the eye. A person with colour-blindness has trouble seeing red, green, blue, or mixtures of these colors. The most common type is red-green colour-blindness, where red and green are seen as the same color.
[24] EEG is used to detect the functioning of -
A.
Heart
B.
Lung
C.
Kidney
D.
Brain
Ans:
Heart
Explanation :
The electrocardiogram (ECG or EKG) is a diagnostic tool that measures and records the electrical activity of the heart in exquisite detail. The heart is a two stage electrical pump and the heart's electrical activity can be measured by electrodes placed on the skin. The electrocardiogram can measure the rate and rhythm of the heartbeat, as well as provide indirect evidence of blood flow to the heart muscle.
[25] The metal, which is a constituent of vitamin B12 is -
A.
Iron
B.
Magnesium
C.
Zinc
D.
Cobalt
Ans:
Cobalt
Explanation :
Vitamin B12 is a "generic descriptor for compounds exhibiting the biologic activity of cyanocobalarnin: the antianemia factor of liver extract that contains cobalt, a cyano group, and coffin in a cobamide structure. Vitamin B12 is vital for the formation of red blood cells, as well as for the proper functioning and health of nerve tissue. If left untreated, vitamin B12 deficiency, also known as B12 deficiency, can lead to anemia, as well as nerve and brain damage, which may eventually become irreversible.
Explanation :
Neutering involves removing the source of the hormones that control reproduction and that determine the typical physical and behavioral characteristics that distinguish males and females. In dogs and cats, this is usually done by surgically removing the testicles in males (castration) and the ovaries in females (spaying). The primary purpose of neutering is to prevent reproduction.

This causes the image that one sees when looking at a distant object to be out of focus but in focus when looking at a close object. Eye care professionals most commonly correct myopia through the use of corrective lenses, such as glasses or contact lenses. It may also be corrected by refractive surgery, though there are cases of associated side effects.
[23] A man with colour blindness will see red as -
A.
Yellow
B.
Blue
C.
Green
D.
Violet
Ans:
Green
Explanation :
Colour-blindness is the inability to distinguish the differences between certain colours. This condition results from an absence of colour-sensitive pigment in the cone cells of the retina, the nerve layer at the back of the eye. A person with colour-blindness has trouble seeing red, green, blue, or mixtures of these colors. The most common type is red-green colour-blindness, where red and green are seen as the same color.
[24] EEG is used to detect the functioning of -
A.
Heart
B.
Lung
C.
Kidney
D.
Brain
Ans:
Heart
Explanation :
The electrocardiogram (ECG or EKG) is a diagnostic tool that measures and records the electrical activity of the heart in exquisite detail. The heart is a two stage electrical pump and the heart's electrical activity can be measured by electrodes placed on the skin. The electrocardiogram can measure the rate and rhythm of the heartbeat, as well as provide indirect evidence of blood flow to the heart muscle.
[25] The metal, which is a constituent of vitamin B12 is -
A.
Iron
B.
Magnesium
C.
Zinc
D.
Cobalt
Ans:
Cobalt
Explanation :
Vitamin B12 is a "generic descriptor for compounds exhibiting the biologic activity of cyanocobalarnin: the antianemia factor of liver extract that contains cobalt, a cyano group, and coffin in a cobamide structure. Vitamin B12 is vital for the formation of red blood cells, as well as for the proper functioning and health of nerve tissue. If left untreated, vitamin B12 deficiency, also known as B12 deficiency, can lead to anemia, as well as nerve and brain damage, which may eventually become irreversible.
Explanation :
Dehydration is the condition where there is acute shortage of water in our body. This occurs when the amount of water leaving our body is greater than the amount consumed. There are three types of dehydration: hypotonic or hyponatremic (primarily a loss of electrolytes, sodium in particular).
[20] The average heart beat rate per minute in a normal person is -
A.
82
B.
92
C.
72
D.
98
Ans:
72
Explanation :
The average heart rate for adult humans is about 70 to 75 beats per minute in a normal relaxed mode. While we tend to think of the "normal" heart beat rate as being "72 beats per minute", in actuality the heart beat rate is not and should not be constant. In fact, the contemporary understanding is that the degree to which the heart beat varies is a key indicator of health and well being. Conversely, the degree to which it does not vary is a key indicator of health risk. The "72 beats per minute" that we are familiar with is the normal average heart beat rate.
[21] HYV refers to -
A.
Hybrid yielding variety
B.
Human yellow virus
C.
High yielding variety
D.
Human yellow vaccine
Ans:
High yielding variety
Explanation :
High Yielding Variety (HYV) seeds played vital role in the progress of agriculture. They are considered as 'miracle seeds'. HYV seeds give better quality yielding. The maturity time of crop is less. Multiple crops can be grown easily. Seeds are mostly flood and drought resistant. Problems of pests and diseases are less. HYV seeds yield more under irrigated conditions. However, the crop demands controlled irrigation. This crop should be irrigated at right time as per the schedule and in right quantity. Most of the HYV seeds are dwarf varieties. They need higher doses of fertilizer.
