Weekly Quiz Competition

Question 1
1 / -0

Mature human red blood cells (RBCs) do not contain __________.

A
Iron

B
Cytoplasm

C
Mitochondria

D
Haemoglobin

Solution

A mature RBC in mammals are devoid of nucleus and most organelles, including mitochondria so that almost the entire cell can be packed with hemoglobin for gaseous transport and becomes even more efficient as an oxygen carrier.
So, option C is the correct answer.
Question 2
1 / -0

Which of the following statements is correct about the loose connective tissues?
I. Areolar tissue and adipose tissue are examples of loose connective tissue.
II. Loose connective tissue has cells and fibres loosely arranged in a semifluid ground substance.
III. Areolar connective tissue connects skin with muscles.
IV. Often areolar connective tissue serves as a support framework for epithelium.

A
All

B
Only II

C
Only III

D
Only I, II and IV
Solution
- Loose connective tissue is a category of connective tissue which includes areolar tissue, reticular tissue, and adipose tissue.
- Loose connective tissue has cells and fibres loosely arranged in a semi-fluid ground substance, for example, areolar tissue present beneath the skin.
- It serves as a support framework for epithelium.
- It is found between the skin and muscles and connects the skin to the underlying muscles.
So, the correct answer is option A.
Question 3
1 / -0

Which one of the following demonstrates the characteristics of cardiac muscle cells?

A
Involuntary and multinucleated

B
Unbranched and uninucleated

C
Cylindrical and uninucleated

D
Unbranched and involutary
Solution
- Cardiac muscles : Branched, cylindrical, Involuntary, Uninucleated.
- Skeletal muscles : Unbranched, Cylindrical, Voluntary, Multinucleated.
- Smooth muscles : Fusiform, Involuntary, Uninucleated.
So, the correct option is 'Cylindrical and uninucleated'.
Question 4
1 / -0

The blood cells, which do not have a nucleus are:

A
Red blood cells

B
White blood cells

C
Blood platelets

D
None of these

Solution

The group of blood cells which are responsible for the transport of oxygen through the blood vessels, across the body are called red blood cells. These cells do not have a nucleus and other cell organelles inside them.
So, the correct answer is Red blood corpuscles.
Question 5
1 / -0

Which of the following is mismatched in terms of its functions?

A
Nervous tissue - Conduction and reflexes.

B
Connective tissue - Binding and support

C
Muscular tissue - Contraction and conduction

D
Epithelial tissue - Protection and absorption

Solution

Muscular tissue has different functions such as maintaining the posture of the body, support the skeleton framework, but not conduction.
Conduction is mainly done by the nervous tissue. Nerve impulses are conducted from one part of the body to the other.
So, the correct answer is option C.
Question 6
1 / -0

The involuntary muscles that cause the wave like contractions pushing food along the intestine are:

A
striated muscles

B
skeletal muscles

C
smooth muscles

D
intercalated muscles

Solution

Smooth muscle is an involuntary muscle present in stomach, intestine & bladder.
So, the correct option is 'smooth muscles'.
Question 7
1 / -0

Cardiac muscle is:

A
involuntary

B
smooth

C
striated

D
both (a) and (c)

Solution

Cardiac muscle or myocardium constitute the main tissue of the walls of the heart ; it is an involuntary, striated muscle.
So, the correct option is 'both (a) and (c)'.
Question 8
1 / -0

Which of the following components of blood fights infection?

A
White blood cells

B
Platelets

C
Red blood cells

D
All of these

Solution

The white blood cells or leukocytes are the blood components primarily involved in fighting the infection.
So, the correct option is 'White blood cells'.
Question 9
1 / -0

Match the items in column I with those in column II:

Column I Column II
(a) Xylem (i) semi-permeable
(b) Phloem (ii) permeable
(c) Cell membrane (iii) downward flow of sap
(d) Root pressure (iv) upward flow of water
(e) Cell wall (v) guttation

A
a)- (iv); (b)- (iii); (c)- (i); (d)- (v); (e)- (ii)

B
a) - (ii) ; b) - (i); c) - (v); d) - (iii) ; e) - (iv)

C
a) - (i); b) - (iii); c) - (iv) ; d) - (v); e) - (ii)

D
a) - (iv); b) - (i); c) - (iii); d) - (v); e) - (ii)
Solution
1. Xylem is a type of complex permanent tissue that is involved in the transport of water.
2. Phloem is another component of the vascular bundle that transports the food material from the leaves to the other parts.
3. The cell membrane is a selectively permeable structure that allows the passage of selected molecules.
4. Guttation is the phenomenon of the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses, and several fungi and it occurs due to the pressure existing within the xylem vessels known as root pressure.
5. The cell wall is the freely permeable outermost covering of plant cells.
Hence the correct option is A.
Question 10
1 / -0

Choose the correct answer from the alternatives given.
The _______ produces red blood cells, which transport _______ and some _______.

A
Liver; oxygen; mineral ions

B
Liver; oxygen; carbon dioxide

C
Bone marrow; oxygen; hormones

D
Bone marrow; oxygen; carbon dioxide

Solution

The bone marrow of long bones produce red blood cells (RBCs), which help in the gaseous transport of oxygen and carbon dioxide with the help of haemoglobin pigment.
So, the correct option is 'D'.
