This particular type of acid is used in sealed lead acid batteries, however, concentration levels differentiate with some brands. These batteries use a combination of lead plates and an electrolyte consisting of a diluted sulphuric acid to convert electrical energy into potential chemical energy and back again.
[8] 'Stone Cancer' occurs due to -
A.
Acid rain
B.
Global warming
C.
Radioactivity

A
B.
B
C.

Carbohydrates
B.
Vitamins
C.
Proteins
D.
Fats
Ans:
Proteins
Explanation :
Pulses are 20 to 25% protein by weight, which is double the protein content of wheat and three times that of rice. While pulses are generally high in protein, and the digestibility of that protein is also high, they are often relatively poor in the essential amino acid methionine.
[25] High level of uric acid in the blood causes -

Arthritis
B.
Gout
C.
Rheumatism
D.
Asthma

A.
Brain
B.
Pulmonary Artery
C.
Aorta
D.
Lungs
Ans:
Aorta

As the left ventricle contracts, the oxygenated blood is pumped into the main artery of the body — the aorta. To get to the aorta, blood passes through the aortic semilunar valve, which serves to keep blood flowing from the aorta back into the left ventricle.
[12] Which one of the following is a condition of delayed blood clotting?
A.
Heaemorrhage
B.
Hematuria
C.
Haemophilia
D.
Anaemia

A.
Violet and orange
B.
Blue and red
C.
Indigo and yellow
D.
Yellow and violet
Ans:
Blue and red
Explanation :
Chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.
[14] 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, fat-soluble vitamins that are needed for the posttranslational modification of certain proteins required for blood coagulation and in metabolic pathways in bone and other tissue. They are 2-methyl-1,4-naphthoquinone (3-) derivatives. This group of vitamins includes two natural vitamers: vitamin K1 (found in highest amounts in green leafy vegetables) and vitamin K2 (form used by enzymes in animals).

Scurvy is caused by the deficiency of Vitamin C. This causes muscle weakness, joint pain and problems with wound healing. It can also lead to loose teeth, bleeding and swollen gums, easily bruised skin and fatigue, and sometimes depression.
[20] Potassium metabisulphate is used as a food preservative for -
A.
Squash
B.
Tomato Ketchup
C.
Fruit Juices
D.
Pickles
Ans:
Fruit Juices
Explanation :
The potassium meta-bisuifite preservative is an additive that is commonly used for preserving all kinds of vegetables and fruit and, thus, increasing their longevity. It finds its application in fruit juices by increasing their longevity. It is also added to dried apples and dehydrated potatoes to preserve their edibility.
[21] Which of these joints is a Hinge joint?
A.
Hip
B.
Elbow
C.
Shoulder
D.
Wrist
Ans:
Elbow
Explanation :
A hinge joint allows movement in a certain spot to take place. This joint is similar to the opening and closing of a door. Some examples of hinge joints are the elbow, knee, ankle and joints between the fingers. Hinge joints allow the body parts to bend and straighten. Hip and shoulders are synovial ball and socket joints.
[22] The oil which causes dropsy is -
A.
Groundnut oil
B.
Coconut oil
C.
Sunflower oil
D.
Argemone oil
Ans:
Argemone oil
Explanation :
Epidemic dropsy is a form of edema of extremities due to intoxication with Argemone Mexicana seed oil. Sanguinarine and dihydrosanguinarine are two major toxic alkaloids of argemone oil, which cause widespread capillary dilatation, proliferation and increased capillary permeability.
[23] Universal donors are people with the blood group -
A.
A
B.
B
C.
O
D.
AB
Ans:
O
Explanation :
Type 0-negative blood does not have any antigens. It is called the "universal donor" type because it is compatible with any blood type. Type AB-positive blood is called the "universal recipient" type because a person who has it can receive blood of any type.
[24] Pulses are a good source of -
A.
Carbohydrates
B.
Vitamins
C.
Proteins
D.
Fats
Ans:
Proteins
Explanation :
Pulses are 20 to 25% protein by weight, which is double the protein content of wheat and three times that of rice. While pulses are generally high in protein, and the digestibility of that protein is also high, they are often relatively poor in the essential amino acid methionine.
[25] High level of uric acid in the blood causes -
A.
Arthritis
B.
Gout
C.
Rheumatism
D.
Asthma
Ans:
Gout
Explanation :
High levels of uric acid in the blood can cause solid crystals to form within joints. This causes a painful condition called gout. If gout remains untreated, these uric acid crystals can build up in the joints and nearby tissues, forming hard lumpy deposits called tophi.
Explanation :
Chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.
[14] 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, fat-soluble vitamins that are needed for the posttranslational modification of certain proteins required for blood coagulation and in metabolic pathways in bone and other tissue. They are 2-methyl-1,4-naphthoquinone (3-) derivatives. This group of vitamins includes two natural vitamers: vitamin K1 (found in highest amounts in green leafy vegetables) and vitamin K2 (form used by enzymes in animals).
[15] The first effective vaccine against polio was prepared by :
A.
J.H. Gibbon
B.
Jonas E. Salk
C.
Robert Edwards
D.
James Simpson
Ans:
Jonas E. Salk
Explanation :
Jonas Edward Salk was an American medical researcher and virologist, best known for his discovery and development of the first polio vaccine. On April 12, 1955, Dr. Thomas Francis, Jr., of the University of Michigan, the monitor of the test results, "declared the vaccine to be safe and effective."
[16] In mammals, an important role of excretion is played by -
A.
Large intestine
B.
Kidneye
C.
Lungs
D.
Liver
Ans:
Kidneye
Explanation :
The Kidneys are bean-shaped organs that serve several excretory roles apart from the essential regulatory roles in mammals.
[17] Milk of magnesia is a suspension of –
A.
magnesium sulphate
B.
magnesium carbonate
C.
magnesium hydroxide
D.
magnesium Chloride
Ans:
magnesium hydroxide
Explanation :
Milk of magnesia is a suspension of magnesium hydroxide due to its milk-like appearance. Milk of magnesia contains magnesium, which is a naturally occurring mineral. The human body requires magnesium to help many of its systems function properly, most notably the muscles and the nerves. Milk of magnesia is also known as magnesium hydroxide, which is its chemical name.
[18] Which virus from the following combinations is contagious for human beings?
A.
H5N1
B.
H1N5
C.
H2N3
D.
H4N2
Ans:
H5N1
Explanation :
A bird-adapted strain of H5N1 , called HPAI A(H5N1) for "highly pathogenic avian influenza virus of type A of subtype H5N1", is the causative agent of H5N1 flu, commonly known as "avian influenza" or "bird flu". It is enzootic in many bird populations, especially in Southeast Asia. One strain of HPAI A(H5N1) is spreading globally after first appearing in Asia.
[19] Which of the following is a deficiency disease?
A.
Asthma
B.
Jaundice
