Question 1
1 / -0

Clumping of RBC may occur when the blood of one person is mixed with the serum or blood of another person. This is due to

A
antigen-antibody reaction

B
antitoxin-antibody reaction

C
antitoxin-antigen reaction

D
antibody-antibody reaction

Solution

Option (1) is the correct answer. Antigen-antibody reaction is a specific chemical interaction between antibodies produced by B cells of the white blood cells and antigens during immune reaction.
Question 2
1 / -0

Which blood group does not have any antigen, but possesses both a and b antibodies?

A
A

B
O

C
B

D
AB

Parents belong to blood group A and B. Blood group of their child will be

A
A or B

B
O

C
AB

D
Any of the above

Question 4
1 / -0

The medium of plasma is

A
acidic

B
basic

C
neutral

D
none

Solution

The medium of plasma is basic as its pH is 7.4.
Question 5
1 / -0

Which of the following is the main function of xylem vessel?

A
Mechanical support

B
Conduction of organic food

C
Conduction of water and minerals

D
Prevention of guttation

Solution

Conduction of water and minerals is the main function of xylem vessels.Vessel elements are typically found in flowering plants (angiosperms) but absent from most gymnosperms such as conifers. Vessel elements are the main feature distinguishing the "hardwood" of angiosperms from the "softwood" of conifers.
Question 6
1 / -0

Which of the following options correctly defines the ascent of sap?

A
Upward movement of water in plants

B
Bidirectional movement of minerals in plants

C
Translocation of organic food in plants

D
Downward movement of organic food in plants

Solution

Option (1) is the correct answer.
Question 7
1 / -0

Where does ascent of sap take place in xylem of a plant?

A
In the tracheids with associated xylem parenchyma

B
In the walls of tracheary element

C
In xylem parenchyma

D
In the lumen of tracheary element

Solution

Ascent of sap takes place in the lumen of tracheary element in xylem of a plant.
Question 8
1 / -0

Which of the following helps to maintain the turgidity of cells?

A
Osmotic pressure

B
Turgor pressure

C
Wall pressure

D
Diffusion pressure

Solution

Turgor pressure helps to maintain the turgidity of cells.Healthy plant cells are turgid and plants rely on turgidity to maintain rigidity.
Question 9
1 / -0

Which of the following causes hot weather wilting in plants?

A
Excessive transpiration and reduced absorption

B
Excessive transpiration and absorption

C
Reduced transpiration and absorption

D
Reduced transpiration and excessive absorption

Solution

Excessive transpiration and reduced absorption causes hot weather wilting in plants.
Question 10
1 / -0

The pulmonary artery carries

A
pure blood to lungs

B
impure blood to lungs

C
pure blood to the intestine

D
None of the above

Solution

The pulmonary artery carries impure blood to lungs.It is one of the only arteries (other than the umbilical arteries in the fetus) that carries deoxygenated blood.
Question 11
1 / -0

If the heart is cut out from the body of a frog,

A
it will continue beating for a long time if it is kept moist

B
it will continue beating for a long time if it is kept dry

C
it will not beat at all

D
None of the above

Solution

If the heart is cut out from the body of a frog, it will continue beating for a long time if it is kept moist. The poikilotherm heart has a built-in pacemaker (a group of neural cells sending out regular impulses) allowing the heart to beat for hours even after the brain is no longer connected to the heart.
Question 12
1 / -0

In mammals, the role of spleen is to

A
assist the kidney

B
assist the liver

C
control blood pressure

D
act as hematopoietic organ

Solution

In mammals, the role of spleen is to assist the liver.The spleen acts as a blood filter; it controls the amount of red blood cells and blood storage in the body, and helps to fight infection.
Question 13
1 / -0

Leukopenia is the condition when

A
bone marrow is destroyed

B
the total number of lymphocytes decreases from 2% to 0.5%

C
the total number of leukocytes increases above 6,000 per cubic mm

D
the total number of leukocytes decreases below 5000 per cubic mm

Solution

Leukopenia is the condition when the total number of leukocytes decreases below 5000 per cubic mm. Leukopenia can be identified with a complete blood count..
Question 14
1 / -0

The weight of heart of men varies from 280 to 340 g. In women, it varies from

A
200 - 300 g

B
300 - 400 g

C
230 - 280 g

D
250 - 290 g

Solution

The weight of heart of men varies from 280 to 340 g. In woman, it varies from 230 - 280 g.
Question 15
1 / -0

If the pacemaker is absent,

A
only auricles will contract

B
only ventricles will contract

C
cardiac muscles will contract in a coordinated manner

D
cardiac muscles will not contract in a coordinated manner

Solution

If the pace maker is absent, cardiac muscles will contract in a coordinated manner because pace maker sets the rhythmic contractions.
Question 16
1 / -0

The phase of contraction of the heart is termed as

A
heartbeat

B
systole

C
diastole

D
heart sound

Solution

The phase of contraction of the heart is termed as systole.

1 / -0

The auriculo-ventricular node was discovered by

A
William Harvey

B
Ringer

C
Aristotle

D
His

Solution

Option (4) is the correct answer. The atrioventricular node is a part of the electrical conduction system of the heart that coordinates the top of the heart.

A
stomach and intestine

B
pulmonary vein and left auricle

C
right atrium and right ventricle

D
