[16] Process of digestion is helped by -
A.
Enzyme
B.
Hormone
C.
Mineral
D.
Vitamin
Ans:
Enzyme
Explanation :
Enzymes are large biological molecules responsible for the thousands of chemical inter-conversions that sustain life. They are highly selective catalysts, greatly accelerating both the rate and specificity of metabolic reactions, from the digestion of food to the synthesis of DNA. Most enzymes are proteins, although some catalytic RNA molecules have been identified. Enzymes such as amylases and proteases break down large molecules (starch or proteins, respectively) into smaller ones, so they can be absorbed by the intestines.
[17] Glaucoma is a disease of the -
A.
Skin
B.
Lungs
C.
Liver
D.
Eyes
Ans:
Eyes
Explanation :
Glaucoma is an eye disease in which the optic nerve is damaged in a characteristic pattern. This can permanently damage vision in the affected eye(s) and lead to blindness if left untreated. It is normally associated with increased fluid pressure in the eye (aqueous humour). The term "ocular hypertension" is used for people with consistently raised intraocular pressure (MP) without any associated optic nerve damage. Conversely; the term 'normal tension' or slow tension' glaucoma is used for those with optic nerve damage and associated visual field loss, but normal or low TOP.
[18] The chemical used for destroying Fungi in water tanks is -
A.
Copper sulphate
B.
Magnesium sulphate
C.
Zinc sulphate
D.
Nitric acid
Ans:
Copper sulphate
Explanation :
Copper sulfate is a chemical compound which is produced commercially by reacting various copper (II) compounds with sulfuric acid. This compound is used in a wide range of industries, from pyrotechnics to viticulture. It is also known as bluestone or blue vitriol. It is also used in agriculture as a treatment for crops and water systems, as it is a fungicide, herbicide, and pesticide. This compound is commonly sprayed on grapes in the form of a water solution to reduce the risk of fungal infestations.
[19] Which of the following blood cells is compulsory for blood coagulation?
A.
Platelets
B.
Red Blood Corpuscles
C.
White Blood Corpuscles
D.
Lymphocites
Ans:
Platelets
Explanation :
Coagulation is the process by which blood forms clots. It is an important part of homeostasis, the cessation of blood loss from a damaged vessel, wherein a damaged blood vessel wall is covered by a platelet and fibrin-containing clot to stop bleeding and begin repair of the damaged vessel. Platelets immediately form a plug at the site of injury, this is called primary homeostasis.
[20] Which was the first antibiotic -
A.
Terramycin
B.
Neomycin
C.
Penicilin
D.
Streptomycin
Ans:
Penicilin
Explanation :
Penicillin is a group of antibiotics derived from Penicillium fungi. They include penicillin G, procaine penicillin, benzathine penicillin, and penicillin V. Penicillin antibiotics are historically significant because they are the first drugs that were effective against many previously serious diseases, such assyphilis, and infections caused by staphylococci and streptococci. Penicillins are still widely used today, though many types of bacteria are now resistant.
[21] Human kidney disorder is caused by the pollution of -
A.
Cadmium
B.
Iron
C.
Cobalt
D.
Carbon
Ans:
Cadmium
Explanation :
Cadmium (Cd), a by-product of zinc production, is one of the most toxic elements to which man can be exposed at work or in the environment. Once absorbed, Cd is efficiently retained in the human body, in which it accumulates throughout life. Cd is primarily toxic to the kidney, especially to the proximal tubular cells, the main site of accumulation. Cadmium accumulation in the kidneys and may sometimes cause kidney failure when it is in excess.
[22] Dehydration in human body is caused due to the deficiency of -
A.
Vitamin
B.
Salt
C.
Hormone
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.
[23] Which is the organ that excretes water, fat and various catabolic wastes :
A.
Kidney
B.
Skin
C.
Spleen
D.
Salivary glands
Ans:
Kidney
Explanation :
The kidneys are organs that serve several essential regulatory roles in most animals, including vertebrates and some invertebrates. They 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 (via maintaining salt and water balance).
[24] Blood Circulation was discovered by -
A.
Mary Anderson
B.
Virginia Apgar
C.
William Harvey
D.

Ans:
involuntary muscle
Explanation :
Cardiac muscle is also an involuntary muscle, found only in the heart.
Explanation :
James D Watson and Fracis Crick, the two scientists who discovered the structure of DNA in 1953. Watson and Crick took a crucial conceptual step, suggesting the molecule was made of two chains of nucleotides, each in a helix as Franklin had found, but one going up and the other going down. Crick had just learned of Chargaffs findings about base pairs in the summer of 1952. He added that to the model, so that matching base pairs interlocked in the middle of the double helix to keep the distance between the chains constant.
[12] Virus contains -
A.
Protein and lipid
B.
Nucleic acid and protein
C.
Lipid and carbohydrate
D.
Carbohydrate and nucleic acid
Ans:
Protein and lipid
Explanation :
Virus particles (known as virions) consist of two or three parts: the genetic material made from either DNA or RNA, long molecules that carry genetic information, a protein coat that protects these genes, and in some cases an envelope of lipids that surrounds the protein coat when they are outside a cell. The shapes of viruses range from simple helical and icosahedra forms to more complex structures.
