Mycobacterial infections are notoriously difficult to treat. The organisms are hardy due to their cell wall, which is neither truly Gram negative nor positive. In addition, they are naturally resistant to a number of antibiotics that disrupt cell-wall biosynthesis, such as penicillin.
[19] The enzyme that is present in the saliva of man is -
A.
Pepsin
B.
Renin
C.

Explanation :
Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylase is present in human saliva, where it begins the chemical process of digestion. Foods that contain much starch but little sugar, such as rice and potato, taste slightly sweet as they are chewed because amylase turns some of their starch into sugar in the mouth. The pancreas also makes amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. Plants and some bacteria also produce amylase. As diastase, amylase was the first enzyme to be discovered and isolated.

It is a hospital-based specialty, and is usually practiced in neonatal intensive care units (NICUs). The principal patients of neonatologists are newborn infants who are ill or requiring special medical care due to prematurity, low birth weight, intrauterine growth retardation, congenital malformations (birth defects), sepsis, pulmonary hyperplasia or birth asphyxia.
[17] Which one of the following does not secrete any digestive enzyme?
A.
Liver
B.
Salivary gland
C.
Glands of small intestine
D.
Pancreas
Ans:
Liver
Explanation :
Digestive enzymes are enzymes that break down polymeric macromolecules into their smaller building blocks, in order to facilitate their absorption by the body. Digestive enzymes are found in the digestive tracts of animals (including humans) and in the traps of carnivorous plants, where they aid in the digestion of food, as well as inside cells, especially in their lysosomes, where they function to maintain cellular survival. Digestive enzymes are diverse and are found in the saliva secreted by the salivary glands, in the stomach secreted by cells lining the stomach, in the pancreatic juice secreted by pancreatic exocrine cells, and in the intestinal (small and large) secretions, or as part of the lining of the gastrointestinal tract.
[18] The causative agent of Tuberculosis is -
A.
Mycobacterium
B.
Aspergillus
C.
Rhabdovirus
D.
HIV.
Ans:
Mycobacterium
Explanation :
Mycobacterium is a genus of Actinobacteria, given its own family, the Mycobacteriaceae. The genus includes pathogens known to cause serious diseases in mammals, including tuberculosis and leprosy. Mycobacterial infections are notoriously difficult to treat. The organisms are hardy due to their cell wall, which is neither truly Gram negative nor positive. In addition, they are naturally resistant to a number of antibiotics that disrupt cell-wall biosynthesis, such as penicillin.
[19] The enzyme that is present in the saliva of man is -
A.
Pepsin
B.
Renin
C.
Amylase
D.
Trypsin
Ans:
Amylase
Explanation :
Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylase is present in human saliva, where it begins the chemical process of digestion. Foods that contain much starch but little sugar, such as rice and potato, taste slightly sweet as they are chewed because amylase turns some of their starch into sugar in the mouth. The pancreas also makes amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. Plants and some bacteria also produce amylase. As diastase, amylase was the first enzyme to be discovered and isolated.
[20] The seeds of certain plants fail to germinate if they do not pass through the digestive tract of fruit-eating birds. This is due to -
A.
hibernation
B.
seed coat impermeability
C.
infertility
D.

Ans:
seed coat impermeability
Explanation :
A dormant seed is one that is unable to germinate in a specified period of time under a combination of environmental factors that are normally suitable for the germination of the non-dormant seed. Dormancy is a mechanism to prevent germination during unsuitable ecological conditions, but the probability of seedling survival is low.

Haemocytometer
Ans:
Sphygmomanometer
Explanation :
A sphygmomanometer or blood pressure meter is a device used to measure blood pressure, composed of an inflatable cuff to restrict blood flow, and a mercury or mechanical manometer to measure the pressure. It is always used in conjunction with a means to determine at what pressure blood flow is just starting, and at what pressure it is unimpeded. Manual sphygmomanometers are used in conjunction with a stethoscope. The device was invented by Samuel Siegfried Karl Ritter von Basch in 1881.
[9] The term 'Rh factor' refers to -
A.
Rhesus factor
B.
Rheumatoid factor
C.
Renal factor
D.
Rhombic factor
Ans:
Rhesus factor
Explanation :
Each person's blood is one of four major types: A, B, AB, or O. Blood types are determined by the types of antigens on the blood cells. Antigens are proteins on the surface of blood cells that can cause a response from the immune system. The Rh factor (Rhesus factor) is a type of protein on the surface of red blood cells. Most people who have the Rh factor are Rh-positive.

vitamin B
C.
vitamin C
D.
vitamin D
Ans:
vitamin C
Explanation :
Vitamin C or L-ascorbic acid, or simply ascorbate the anion of ascorbic acid), is an essential nutrient for humans and certain other animal species. Vitamin C is found in high concentrations in immune cells, and is consumed quickly during infections. It is not certain how vitamin C interacts with the immune system: it has been hypothesized to modulate the activities of phagocytes, the production of cytokines and lymphocytes, and the number of cell adhesion molecules in monocytes.
[15] The normal RBC count in adult male is -
A.
5.5 million
B.
5.0 million
C.
4.5 million
D.
4.0 million
Ans:
5.0 million
Explanation :
An RBC count is a blood test that tells how many red blood cells (RBCs) we have. RBCs contain hemoglobin, which carries oxygen. How much oxygen our body tissues get depends on how many RBCs we have and how well they work. The general the range is as follows: Male: 4.7 to 6.1 million cells per micro liter (cells/meld); and Female: 4.2 to 5.4 million cells/meld.
[16] Study of newly born up to the age of 3 months is called -
A.
Chorology
B.
Conchology
C.
Nematology
D.
Neonatology
Ans:
Neonatology
Explanation :
Neonatology is a subspecialty of pediatrics that consists of the medical care of newborn infants, especially the ill or premature newborn infant. It is a hospital-based specialty, and is usually practiced in neonatal intensive care units (NICUs). The principal patients of neonatologists are newborn infants who are ill or requiring special medical care due to prematurity, low birth weight, intrauterine growth retardation, congenital malformations (birth defects), sepsis, pulmonary hyperplasia or birth asphyxia.
[17] Which one of the following does not secrete any digestive enzyme?
A.
Liver
B.
Salivary gland
C.
Glands of small intestine
D.
Pancreas
Ans:
Liver
Explanation :
Digestive enzymes are enzymes that break down polymeric macromolecules into their smaller building blocks, in order to facilitate their absorption by the body. Digestive enzymes are found in the digestive tracts of animals (including humans) and in the traps of carnivorous plants, where they aid in the digestion of food, as well as inside cells, especially in their lysosomes, where they function to maintain cellular survival. Digestive enzymes are diverse and are found in the saliva secreted by the salivary glands, in the stomach secreted by cells lining the stomach, in the pancreatic juice secreted by pancreatic exocrine cells, and in the intestinal (small and large) secretions, or as part of the lining of the gastrointestinal tract.
[18] The causative agent of Tuberculosis is -
A.
Mycobacterium
B.
Aspergillus
C.
Rhabdovirus
D.
HIV.
Ans:
Mycobacterium
Explanation :
Mycobacterium is a genus of Actinobacteria, given its own family, the Mycobacteriaceae. The genus includes pathogens known to cause serious diseases in mammals, including tuberculosis and leprosy. Mycobacterial infections are notoriously difficult to treat. The organisms are hardy due to their cell wall, which is neither truly Gram negative nor positive. In addition, they are naturally resistant to a number of antibiotics that disrupt cell-wall biosynthesis, such as penicillin.
[19] The enzyme that is present in the saliva of man is -
A.
Pepsin
B.
Renin
C.
Amylase
D.
Trypsin
Ans:
Amylase
Explanation :
Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylase is present in human saliva, where it begins the chemical process of digestion. Foods that contain much starch but little sugar, such as rice and potato, taste slightly sweet as they are chewed because amylase turns some of their starch into sugar in the mouth. The pancreas also makes amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. Plants and some bacteria also produce amylase. As diastase, amylase was the first enzyme to be discovered and isolated.
[20] The seeds of certain plants fail to germinate if they do not pass through the digestive tract of fruit-eating birds. This is due to -
A.
hibernation
B.
seed coat impermeability
C.
infertility
D.
vegetative reproduction
Ans:
seed coat impermeability
Explanation :
A dormant seed is one that is unable to germinate in a specified period of time under a combination of environmental factors that are normally suitable for the germination of the non-dormant seed. Dormancy is a mechanism to prevent germination during unsuitable ecological conditions, but the probability of seedling survival is low.
[21] Animals having open circulatory system POSSESSES -
A.
coelenteron
B.
spongocoel
C.
pseudocoel
D.
haemocoel
Ans:

Ans:
seed coat impermeability
Explanation :
A dormant seed is one that is unable to germinate in a specified period of time under a combination of environmental factors that are normally suitable for the germination of the non-dormant seed. Dormancy is a mechanism to prevent germination during unsuitable ecological conditions, but the probability of seedling survival is low.
[21] Animals having open circulatory system POSSESSES -
A.
coelenteron
B.
spongocoel
C.
pseudocoel
D.
haemocoel
Ans:
haemocoel
Explanation :
Open circulatory system is the one in which blood does not circulate only inside blood vessels but it also falls in cavities that irrigate tissues. The internal organs are suspended in a network of blood-filled sinuses or open spaces which collectively form the haemocoel.
[22] Which of the following weeds has been found useful to check water pollution caused by industrial affluents?
A.
Parthenium
B.
Elephant grass
C.
Water hyacinth
D.
Both (1) and (2) above
Ans:
Water hyacinth
Explanation :
Around the world, there is an increasing trend in areas of land, surface waters and groundwater affected by contamination from industrial, military and agricultural activities due to either ignorance, lack of vision, or carelessness.
[23] Which of the following is correlated with blood pressure?
A.
Liver
B.
Testis
C.
Pancreas
D.
Adrenal
Ans:
Adrenal
Explanation :
Blood pressure is an important indicator of adrenal health and function. Mild adrenal weakness is usually accompanied by normal to high blood pressure. As Adrenal Fatigue advances, low blood pressure, at rest or related to posture becomes more prevalent.
[24] Blood cancer is otherwise called as -
A.
Anaemia
B.
Polycythemia
C.
Leucopenia
D.
Leukemia
Ans:
Leukemia
Explanation :
Leukemia is a type of cancer of the blood or bone marrow characterized by an abnormal increase of immature white blood cells called "blasts". Leukemia is a broad term covering a spectrum of diseases. In turn, it is part of the even broader group of diseases affecting the blood, bone marrow, and lymphoid system, which are all known as hematological neoplasms.
[25] Which one of the following glands in the human body stores iodine?
A.
Parathyroid
B.
Thyroid
C.
Pituitary
D.
Adrenal
Ans:
Thyroid
Explanation :
Iodine is mostly concentrated in thyroid gland. A healthy adult body contains 15-20 mg of iodine, 70- 80% of which is stored in the thyroid gland
Explanation :
Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylase is present in human saliva, where it begins the chemical process of digestion. Foods that contain much starch but little sugar, such as rice and potato, taste slightly sweet as they are chewed because amylase turns some of their starch into sugar in the mouth. The pancreas also makes amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. Plants and some bacteria also produce amylase. As diastase, amylase was the first enzyme to be discovered and isolated.
[20] The seeds of certain plants fail to germinate if they do not pass through the digestive tract of fruit-eating birds. This is due to -
A.
hibernation
B.
seed coat impermeability
