Question 1
1 / -0

Which of the following is known as the building block of proteins?

A
Amino acids

B
Enzymes

C
Fatty acids

D
Glycogen

Solution

Amino acids are directly absorbed into blood stream. Blood carries these amino acids to the tissues where they become part of the metabolic pool, from which body proteins are synthesized. Hence, it is known as the building block of proteins.
Question 2
1 / -0

.................. means supply of the essential organic and inorganic chemical compounds to the body.

A
Food

B
Nutrition

C
Meal

D
Appetile

Solution

Nutrition means supply of the essential organic and inorganic chemical compounds (proteins, vitamins, salts, carbohydrates, etc) to the body. All such chemical compounds are called nutrients.
Question 3
1 / -0

Goblet cells are abundant in

A
Large intestine

B
Small intestine

C
Ileum

D
Stomach

Solution

The wall of the large intestine is lined with simple columnar epithelium. Instead of having the evaginations of the small intestine (villi), the large intestine has invaginations (the intestinal glands). While both the small intestine and the large intestine have goblet cells, they are abundant in the large intestine.
Question 4
1 / -0

Diarrhea can be caused by

A
Bacteria

B
Virus

C
Both A and B

D
None of the above

Solution

Diarrhea is a condition that’s characterized by the appearance of loose, watery stools or a frequent need to have a bowel movement. Diarrhea can be related to a viral or bacterial infection, or it can be the result of food poisoning. Rotavirus, norovirus and adenovirus are the common viruses which causes diarrhea. Campylobacter, Shigella are the common bacterias which causes diarrhea. Hence option C is correct.
Question 5
1 / -0

The condition in which feces are discharged from the bowels frequently and in a liquid form is

A
Diarrhoea

B
Typhoid

C
Tetanus

D
Malaria
Solution
Diarrhoea is a condition in which faeces are discharged from the bowels frequently and in a liquid form.
Diarrhoea is one of the most common health complaints. It can range from a mild, temporary condition, to a potentially life-threatening one.
Most cases of diarrhoea are caused by an infection in the gastrointestinal tract. The microbes responsible for this infection include:
Bacteria
Viruses
Parasitic organisms
So, the correct answer is 'Diarrhoea'.
Question 6
1 / -0

Finger like projections present in large intestine are called _____

A
Jejunum

B
Colon

C
Villi

D
Rectum

Solution

Digestion ends in small intestine. Waste products are excreted from our body through large intestine. Excess water and salts are absorbed from intestine through muscular finger like projections called Villi.
Question 7
1 / -0

The salivary amylase shows maximum digestive action at pH ______________.

A
$$3.6$$

B
$$6.8$$

C
$$7.5$$

D
$$8.5$$

Solution

The optimum pH for the enzymatic activity of salivary amylase ranges from 6 to 7. Above and below this range, the reaction rate reduces as enzymes get denaturated. The enzyme salivary amylase is most active at pH 6.8. It is the optimum pH of salivary amylase. Our stomach has high level of acidity which causes the salivary amylase to denature and change its shape. So, the salivary amylase does not function once it enters the stomach.
So, the correct answer is '6.8'6.8
Question 8
1 / -0

I.- Large intestine absorbs salts and water.
II.- Villi are present in large intestine.

A
I and II both are true

B
I and II both are false

C
I is false, II is true

D
I is true, II is false
Solution
- By the time food reaches the large intestine, most digestion and absorption have already taken place.
- The purpose of the large intestine is to absorb remaining water and salts from the material that has not been digested as food
- In the large intestine, villi, microvilli, and crypts are not present, only small intestine contains tiny projections called villi and microvilli, to increase the total area for absorption.
So, the correct option is D.
Question 9
1 / -0

Find the odd one:

A
Colon

B
Cecum

C
Rectum

D
Duodenum

Solution

Residue of digested food passes into large intestine. Large intestine has three regions i.e C shaped colon, cecum and thick tubular rectum.
Question 10
1 / -0

Find the odd one out.

A
Saw fish

B
Sardine

C
Bombay duck

D
Myxine

Solution

Correct Answer: D
Explanation:
• Sawfish, sardine, and Bombay duck are all members of the Pisces superclass and division Gnathostomata.
• Myxine belongs to the Division: Agnatha and has a circular sucking mouth.
Hence, myxine is the odd one out.
