Weekly Quiz Competition

Question 1
1 / -0

Frogs differ from humans in possessing

A
Paired cerebral hemispheres

B
Hepatic portal system

C
Nucleated red blood cells

D
Thyroid as well as parathyroid

Solution

Mammals have red blood cells lacking a nucleus. Other vertebrates, such as fish, reptiles and birds, have red blood cells that contain an inactive nucleus. Since carrying oxygen is the primary function of red blood cells, losing the nucleus means that these cells can pack more hemoglobin molecules per unit body weight. Frogs have a nucleus because they don't need much oxygen. Humans don't have a nucleus in their red blood cells because they need more oxygen than frogs, so our red blood cells eliminated the nucleus to fit more oxygen in. Frogs can breathe underwater and in air, so they don't need much oxygen, so their red blood cells didn't eliminate the nucleus.
Hence the correct option is C.
Question 2
1 / -0

Choose the correctly matched pair.

A
Tendon - Specialized connective tissue

B
Adipose tissue - Dense connective tissue

C
Areolar tissue - Loose connective tissue

D
Cartilage - Loose connective tissue
Solution
- Loose connective tissue is a category of connective tissue, which includes areolar tissue, reticular tissue, and adipose tissue.
- A tendon is a fibrous connective tissue, which attaches muscle to bone.
- Cartilage is a skeletal connective tissue in animals and is found in the joints between bones, the rib cage, the ear, the nose, the bronchial tubes.
  So, the correct answer is option C.
Question 3
1 / -0

Which one of the following is correct?

A
Lymph = Plasma + RBC + WBC

B
Blood = Plasma + RBC + WBC + Platelets

C
Plasma = Blood - Lymphocytes

D
Serum = Blood + Fibrinogen
Solution
- Lymph has a similar composition to blood plasma and when initially formed, lymph is relatively colourless. Depending on where the lymph travels, the lymph will contain different concentrations of lymphocytes, proteins and fats. Lymph contains a variety of substances, including proteins, salts, glucose, fats, water, and white blood cells. Unlike blood, lymph does not normally contain any red blood cells.
- Blood plasma is composed of plasma, RBC, WBC and platelets.
- In blood, the serum is the component that is neither a blood cell (serum does not contain white or red blood cells) nor a clotting factor; it is the blood plasma with the fibrinogens removed.
Hence the correct option is B.
Question 4
1 / -0

Match the following columns and select the correct option.

Column - I Column - II
(a) Eosinophils (i) Immune response
(b) Basophils (ii) Phagocytosis
(c) Neutrophils (iii) Release histaminase, destructive
enzymes
(d) Lymphocytes (iv) Release granules containing histamine

A
$$(a)- (iv), \ (b)- (i), \ (c)- (ii), \ (d)- (iii)$$

B
$$(a)- (i), \ (b)- (ii), \ (c)- (iv), \ (d)- (iii)$$

C
$$(a)- (ii), \ (b)- (i), \ (c)- (iii), \ (d)- (iv)$$

D
$$(a)- (iii), \ (b)- (iv), \ (c)- (ii), \ (d)- (i)$$
Solution
- Eosinophils - Releases histamine, destructive enzymes.
- Basophils - are the cells with granules containing histamine.
- Neutrophils - are the phagocytic cells. They kill the microbes.
- Lymphocytes - are the cells that are part of the acquired immune system. They generate immune responses.
Thus, the correct answer is (D) - (a)−(iii), (b)−(iv), (c)−(ii), (d)−(i).
Question 5
1 / -0

Smooth muscles are

A
Involuntary, cylindrical, striated

B
Voluntary, spindle-shaped, uninucleate

C
Involuntary, fusiform, non-striated

D
Voluntary, multinucleate, cylindrical
Solution
Correct option: C
Explanation:
Smooth muscles are located in the walls of hollow internal organs and exhibit involuntary contraction.
Smooth muscle fibres are spindle-shaped cells, uninucleated and are arranged in parallel lines to form sheets.
The absence of light and dark bands make these muscles non-striated.
Question 6
1 / -0

The cells lining the blood vessels belong to the category of:

A
Smooth muscle tissue.

B
Squamous epithelium.

C
Columnar epithelium.

D
Connective tissue.

Solution

Correct option - B
Explanation for correct option -
Cells lining our blood vessels belong to squamous epithelial tissue. These cells look like skinny, flat plates and have elliptical nuclei.
Question 7
1 / -0

Select the correct match.
A Smooth muscle 1 Present in the wall of the intestine
B Areolar tissue 2 Stores fats
C Bone 3 Tip of nose
D Cuboidal epithelium 4 Present in skin

A
A - 1

B
B - 2

C
C - 3

D
D - 4

Solution

Smooth muscle is a non-striated muscle that is mainly involved in involuntary actions. It is present in the walls of the small intestine.
Adipose tissue stores fats, not areolar tissue.
Cartilage is present at the tip of the nose.
Stratified squamous epithelium is present in the skin. Cuboidal epithelium forms the lining of ducts of salivary glands and lining of kidney tubules.
So, the correct answer is option A.
Question 8
1 / -0

Given is the diagrammatic sketch of a certain type of connective tissue. Identify the parts labeled A, B, C and D and select the right option about them

A
Part-A: Mase cell; Part-B: Marcophage; Part-C: Fibroblase; Part-D: Collagen fibres

B
Part-A: Macrophage; Part-B: Collegen fibres; Part-C: Fibroblast; Part-D: Macrophage

C
Part-A: Macrophage; Part-B: Collagen fibres; Part-C: Fibroblast; Part-D: Macrophage

D
Part-A: Macrophage; Part-B: Fibroblast; Part-C: Collagen fibres; Part-D: Mast cell

Solution

A macrophage is a type of white blood cell derived from monocytes and is responsible for detecting, engulfing and destroying pathogens and apoptotic cells. They do this by the process called phagocytosis. Fibroblasts are large, flat cells with many branching processes. They secrete collagen fibers. Collagen fibers are unbranched, wavy and arranged in bundles. They contain a proteinous substance called collagen. Mast cells contain heparin and histamine granules in their cytoplasm. Heparin prevents clotting of blood and histamine carry out vasodilation.
Thus, the correct answer is option D.
Question 9
1 / -0

Clotting of blood at injured parts is carried out by

A
Red blood corpuscles.

B
Lymph.

C
White blood corpuscles.

D
Blood platelets.

Solution

Platelets help in blood clotting. They are smaller than red or white blood cells. Blood clotting is the process by which blood changes from liquid to gel and stop bleeding. When the blood vessels get injured, platelets in blood produces prothrombin in the presence of vitamin K. The prothrombin then converts into the thrombin (active form) in the presence of thrombokinase and calcium ions. This thrombin then converts fibrinogen (inactive) into the fibrin (active). Fibrin thread then plugs the damaged part and appear like a clot.
Thus, the correct answer is option D.
Question 10
1 / -0

Given are the figures of three kinds of muscle fibres. Which one would you find in the grasshopper's legs?

A
A only

B
B only

C
A and C

D
B and C

Solution

The muscles which are present in the legs of a grasshopper are the skeletal muscles. The flexor and extensor muscles which are connected to the tibia bone are the forms of skeletal muscles. These are cylindrical muscle fibres with striations. The myosin and actin filaments make up the muscle fibre.
Thus, the correct answer is option B.
