Weekly Quiz Competition

Question 1
1 / -0

Read the following $$(A-D)$$:-
A. RBCs are the most abundant of all the cells in the blood.
B. A healthy adult man has an average of $$5$$ Billions to $$5.5$$ Billions of RBCs $$ /mm^{-3}$$ of blood.
C.RBCs are formed in the liver in adults.
D.RBCs are devoid of the nucleus in most mammals and are biconcave in shape.
How many of the above statements are incorrect?

A
$$4$$

B
$$3$$

C
$$2$$

D
$$1$$

Solution

A. RBCs are the most abundant of all the cells in blood because of their function to transport oxygen to the tissues.
B. A healthy adult man has on an average 4.5 to 5.9 million mm$$^{-3}$$ of RBCs in the blood.
C. In adults, the RBCs are formed in the red bone marrow.
D. In most mammals, the RBCs are devoid of the nucleus and are biconcave in shape.
Hence, the correct answer is '2.'
Question 2
1 / -0

Neurilemma is name for:

A
Plasmamembrane of axon

B
Coating formed by myelin sheath

C
Covering of schwann cells

D
Connective tissue covering of nerve fasciculus

Solution

Neurilemma is the outermost covering of Schwann cells that surrounds the axon of a neuron. It is also known as neurolemma.
Thus, the correct answer is 'Covering formed by Schwann cells.'
Question 3
1 / -0

Bone possesses a solid matrix composed of

A
Suberin, lignin

B
Calcium, phosphorus

C
Osteocytes

D
All of the above

Solution

Suberin is present as a covering on the bark which makes it impervious to water and gases.
Lignin is present in the cells such as chlorenchyma which makes the cell wall thick.
Calcium and phosphorus are two very important components of the bones that make the solid matrix. These two elements are very essential to the bones functionally as well as structurally.
Osteocytes are just the cells which make up the bones.
Thus, the correct answer is 'Calcium, phosphorus.'

Question 4

1 / -0

Two articulating bones are connected by

Tendon

Cartilage

Ligament

Fibres

Solution

Tendon	It connects muscle to the bone
Cartilage	It is a connective tissue, which is present between the articulated region of bones. it provides support as well as flexibility to the bone.
Ligament	It is fibrous connective tissue, which connects one bone to another bone.
Fibres	Muscle is made up of fibres (type I, type II, type III). It helps in the muscle contraction.

So, the correct answer is 'Ligament'.

Question 5
1 / -0

Match the columns and find out the correct combination.

Name of muscle fibres Arrangement Power of regeneration
A. Skeletal In bundles Limited
B. Unstriated In sheets Absent
C. Cardiac As network High
D. Smooth skeletal In sheets Greater than cardiac muscle

A
B and C

B
A and D

C
C and D

D
B and D

Solution

1. Skeletal muscles occur in the form of bundles and have a limited power of regeneration.
2. Smooth or unstriated muscles are arranged in the form of sheets and possess power of regeneration.
3. Cardiac muscles are striated and form network and have almost no power of regeneration.
4. Smooth skeletal muscles are also found in the form of sheets and have more regeneration capacity than cardiac muscles.
So, the correct option is 'A and D'.
Question 6
1 / -0

Which one is smallest?

A
Eosinophil

B
Basophil

C
Neutrophil

D
Monocyte

Solution

A.Eosinophil - These cells are 10 - 15 µm in diameter

B.Basophils - They are 14-16 µm in diameter,

C.Neutrophil – The cells are 12 to 17 µm in diameter

D.Monocyte – The cells are 15 to 30 µm in diameter.
So, the correct option is ‘Eosinophils’.
Question 7
1 / -0

The short lived meristem present between two permanent tissue

A
Apical meristems

B
Interfascicular cambium

C
Intercalary meristem

D
Lateral meristems

Solution

Intercalary meristem is present at internodes or stem locales between the spots at which leaves connect and leaf bases, particularly of specific monocotyledons, e.g. grasses.
So, the correct option is 'C'.
Question 8
1 / -0

Which of these tissues is responsible for contractions that allow the movement of substances?

A
Muscular

B
Nervous

C
Epithelial

D
Connective

Solution

The contractions produced by the muscular tissue helps in the movement of various substances in the body. For example, peristaltic movements involve the contractions of smooth muscles of the oesophagus in order to facilitate the movement of the food particles.
So, the correct option is option A.
Question 9
1 / -0

According to you, which muscle cell will have the highest number of mitochondria?

A
Muscle cell of thigh

B
Cardiac muscle cell

C
Muscle cell of arm

D
All of the above

Solution

Mitochondria are the organelles of cells that produce energy in the form of ATP. These organelles synthesize ATP from food that we eat, and are hence, called the powerhouses of cells.
The highest number of mitochondria is found in cardiac muscle cells because the muscles of the heart work continuously and require lots of energy.
So, the correct answer is 'Cardiac muscle cell'.
Question 10
1 / -0

Choose the incorrect feature of epidermis.

A
Living

B
Parenchymatous

C
Always single layered

D
May have cutin deposition

Solution

The epidermis usually consists of a single layer of cells and is the outermost layer present on leaves, stems and roots of plants. The epidermis consists of living parenchyma cells. In most plant stems and leaves, cutin, a fatty substance, is often deposited on the outer surface of the epidermal cell wall to form a cuticle over which wax may also be deposited. Generally, epidermis is single-layered, but in xerophytes it is multilayered.
So, the correct option is C.
