Weekly Quiz Competition

Question 1
1 / -0

Type of muscle present in our ____________________.

A
Heart are involuntary and unstriated smooth muscles

B
Intestine are striated and involuntary muscles

C
Thigh are striated and voluntary muscles

D
Upper arm are spindle shaped and involuntary muscles

Solution

Heart muscles are striated, involuntary, cylindrical and branched.
Intestine is made of spindle shaped, involuntary and smooth muscles.
The muscles of the upper arm are striated, cylindrical and voluntary.
Thigh muscles are a type of skeletal muscles that are striated and voluntary in nature. These muscle tissues are closely attached to the skeletal bones.
So, the correct answer is C.
Question 2
1 / -0

Which salt predominates in bone matrix?

A
Sodium chloride

B
Sodium carbonate

C
Calcium phosphate

D
Magnesium phosphate

Solution

Bone has 60% inorganic component -mostly salts of calcium phosphate.
So the correct answer is 'Calcium phosphate'.
Question 3
1 / -0

Which is the loose connective tissue?

A
Nervous system

B
Blood

C
Bone

D
Areolar tissue

Solution

Areolar tissue is an example of loose connective tissue that fills space inside organs and helps in tissue repair.
So, the correct answer is 'Areolar tissue'.
Question 4
1 / -0

Increase in number of leukocytes beyond normal indicates

A
Anaemia

B
Infection

C
Increased defence against pathogen

D
Non-formation of RBC.

Solution

A high white blood cell(leukocyte) count isn't indicative of a specific disease, but it can indicate general problems, such as infection, stress, inflammation, trauma, allergy, or certain diseases. That's why a high white blood cell count usually requires further investigation.

So, the correct answer is 'Infection'.
Question 5
1 / -0

Mesothelium is present in.

A
Body cavity

B
Wall of gut

C
Uterus

D
Wall of blodd vessels

Solution

A. Body cavity
EXPLANATION: Mesothelium is a membrane, which is made up of simple squamous epithelium. It forms the lining of several body cavities, like pleura (thoracic cavity), peritoneum (abdominal cavity), pericardium (heart sac).
Question 6
1 / -0

What is true about RBCs in human?

A
They transport $$99.5\%$$ of $$O_2$$

B
They transport $$80\%$$ oxygen, the rest $$20\%$$ being transported by plasma

C
They do not carry $$CO_2$$ at all

D
They carry $$20-25\%$$ of $$CO_2$$

Solution

The correct answer is D
Nearly 20 to 25% Carbon dioxide is transported by RBC in the form of carbaminohemoglobin ;70% is carried as bicarbonates and 7% in the dissolved form in the plasma.
Question 7
1 / -0

Smooth muscles are

A
Voluntary, spindle-shaped, uninucleated

B
Involuntary, spindle-shaped, non-striated

C
Voluntary, multinucleate, cylindrical

D
Involuntary, cylindrical, straited
Solution
Correct Answer: B
Explanation:
Smooth muscles fibers are tapered at both ends and they do not show striation.
They are fusiform fibers.
Cell junction holds the fibers together and therefore they are bundled together in a connective tissue sheath.
The smooth muscles form walls of internal organs such as blood vessels, stomach, and intestine.
Smooth muscles are involuntary as their functioning can not be directly controlled.
Hence, the correct option is Involuntary, spindle-shaped, non-striated.
Question 8
1 / -0

Largest erythrocytes occur in

A
Llama

B
Whale

C
Amphiuma

D
Musk Deer

Solution

The blood cells are of three major types they are erythrocytes(RBC), leucocytes(WBC) and platelets. Erythrocytes are also called red blood cells due to the presence of the iron-containing protein called Haemoglobin. In llamas, the erythrocytes have a unique shape with high hemoglobin content. Largest erythrocytes occur in Llama.
So, the correct answer is 'Llama'.
Question 9
1 / -0

The cells which do not respire.

A
Epidermal cells

B
Sieve cells

C
Cortical cells

D
Erythrocytes

Solution

Since erythrocytes are devoid of nucleus and organelles including mitochondria, they cannot carry out the process of respiration. Thus, they do not consume any oxygen during transportation.
So, the correct option is 'Erythrocytes'.
Question 10
1 / -0

Which of these produces antibodies?

A
Macrophages

B
Plasma cells/Lymphocytes

C
Mast cells

D
Fibroblasts.

Solution

Antibodies are produced by the plasma cells. Plasma cells are the activated B lymphocytes which are formed when antigen binds with these lymphocytes. Hence the correct option is B.
