A
Protein rich foods

B
Green leafy vegetables

C

Question 2
4 / -1

What is the partial pressure of carbon dioxide in the deoxygenated blood?

A
40 mm Hg

B
45 mm Hg

C
50 mm Hg

D
55 mm Hg

Solution

The partial pressure of carbondioxide in the alveoli is 40 mm Hg. The partial pressure of carbondioxide in the deoxygenated blood in the capillaries is about 45 mm Hg.
Question 3
4 / -1

Which of the following is a occupational lung disease?

A
Silicosis

B
Byssinosis

C
Pneumoconiosis

D
All the above

Solution

The cause of the disorders are-

A) Silicosis – occurs due to the chronic exposure of silica

B) Byssinosis – occurs to workers in the cotton industry

C) Pneumoconiosis – occurs to workers in the coal mining industry
Question 4
4 / -1

Each lip is attached to gum by a ligamentous band called-

A
Wolffian duct

B
Falciform ligament

C
Labial frenulum

D
Palate

Solution

The Labial frenulum often attaches to the center of the upper lip and between the upper two front teeth. This can cause a large gap and gum recession by pulling the gums off the bone. A labial frenectomy removes the labial frenulum.
Question 5
4 / -1

The synthesis of pancreatic hormone, insulin is impaired due to the deficiency of -

A
Vitamin E

B
Iodine

C
Glucose

D
Vitamin C

Solution

Insulin is a polypeptide hormone. It has two chains of 21 and 30 amino acids connected by two disulphide bonds. It is activated by enzymatic bio transformations and impaired by deficiency of Vitamin C. Insulin promotes cellular uptake of vitamin C. Vitamin C raises blood sugar level but also may help in reducing high blood pressure.
Question 6
4 / -1

Which of the following does not act as a diuretic drug?

A
Coffee

B
Cyclosporin

C
Tea

D
Wine

Solution

Diuretics are those drugs that increase the rate of urine flow. Some naturally occurring diuretics are coffee, tea, wine, cola, bear, mixed drinks etc., which inhibits the secretion of ADH causing the formation of dilute urine. Cyclosporin is an immunosuppressant drug used for the purpose of organ transplantation.
Question 7
4 / -1

Which type of muscle contraction regulation can be controlled by acetylcholine neurotransmitter secretion?

A
Skeletal muscle

B
Smooth muscle

C
Cardiac muscle

D
All of these

Solution

Neuromuscular junctions have nerve ending in muscles. Such nerves control the muscle contraction by their efferent motor impulses. Any muscle can be under nervous control.
Question 8
4 / -1

The basophilic granules found in the cyton are formed of endoplasmic reticulum and

A
Golgi complex

B
Ribosomes

C
Lysosomes

D
Exosomes

Solution

The basophilic granules found in the cyton are formed of endoplasmic reticulum and ribosomes. These are the sites for protein synthesis.
Question 9
4 / -1

The photosensitive pigment of cones is of three types which give response to red,green and blue light respectively. They are :

A
Iodopsin ,Porpyrosin and Cyanopsin

B
Porpyrosin, Iodopsin and Cyanopsin

C
Porpyrosin , Cyanopsin and Iodopsin

D
Cyanopsin , Porpyrosin and Iodopsin
Solution
- Cones only operate in the bright light and enables us to see colors.
- The photosynthetic pigment in the cones is of three types namely-Porpyrosin, Iodopsin, and Cyanopsin which give the response to red, green and blue light respectively.
- The sensation of different colors are produced by the various combination of these three types of cones and their photo pigments.
- When the three types of cones are stimulated equally, a sensation of white light is produced.
Question 10
4 / -1

In frog the connection between brain and spinal cord is severed. The leg of such a frog is pricked by a sharp needle. Then it is most likely that the animal will:

A
Not show any reaction

B
Move the leg that is pricked

C
Move the leg and feel the pain

D
Do not move the leg but feel the pain

Solution

When frog is pricked by a sharp needle it is most likely to move the leg that is being pricked as a result of reflex action.
