Question 1
1 / -0

The red worms grind food with the help of ?

A
Gizzard

B
Gills

C
Teeth

D
Pharynx
Question 2
1 / -0

The various kinds of teeth present in human beings are:

A
Premolars and canines

B
Molars and incisors

C
Muscular pharynx and molars

D
Incisors, canines, premolars and molars

Solution

There are several types of teeth and each performs its own special function in the chewing process, depending on its size, shape, location within the jaws. Starting from the midline, the permanent dentition (arrangement of teeth) is comprised of incisors, canines, premolars, and molars.
Therefore, the correct answer is option D.
Question 3
1 / -0

Which of the following is the stomach part in which herbivores secretes the grass which is swallowed quickly?

A
Lumen

B
Pyloric

C
Rumen

D
Ileum
Question 4
1 / -0

Blood vessels and nerves of a tooth are present in

A
Pulp cavity

B
Dentine

C
Crown of a tooth

D
Enamel
Question 5
1 / -0

Which of the following is a soft material in the tooth?

A
Root

B
Dentine

C
Pulp

D
Crown
Question 6
1 / -0

Name the tissues found in tooth.

A
Enamel

B
Cementum

C
Dentin

D
All of the above

Solution

A tooth consists of enamel, dentin, cementum and pulp tissue. The portion of a tooth exposed to the oral cavity is known as the dental crown, and the portion below the dental crown is known as the tooth root. Thus, the correct answer is option D.
Question 7
1 / -0

Which of the following enzymes would be most affected by the overdose of antacid?

A
Maltase

B
Lactase

C
Lipase

D
Pepsin

E
Sucrase

Solution

In the stomach, the enzyme pepsin breaks protein into smaller pieces called polypeptides. For proper functioning of pepsin, acidic pH is necessary. A pH of 2 is optimum for pepsin function. Antacids neutralize the normal stomach acid pH and bring it up to 6 to 7. As pH rises above 4, pepsin activity decreases or stops. That is why when a person takes too much antacid the pH of the stomach may rise to 11, which affects pepsin production severely. Maltase, Lactase, Lipase, and Sucrase are produced in the small intestine and they are active in a pH range from 2 to 6.
So, option D is the correct answer.
Question 8
1 / -0

Dentine is

A
Hard, protective covering on the tooth.

B
The cavity which contains nerves and blood vessels in a tooth.

C
Covering beneath the enamel.

D
The nerve that connects tooth and the brain.

Solution

Dentine is the calcified tissue of the body, is one of the components of the teeth along with enamel, cementum, and pulp. It generally surrounds the entire pulp is a covering beneath the enamel.
Thus, the correct answer is option C.
Question 9
1 / -0

An enzyme that converts starch to simple sugars is known as ________.

A
Amylase

B
Bile juice

C
HCl

D
Pepsin

E
All of the above

Solution

Amylase is an enzyme that breaks down complex starch molecules into simple sugars. Amylase is found in the saliva, present in the mouth. it is also released by the pancreas. Due to the presence of amylase in the saliva, it is said that the digestion process starts from the mouth itself.
Bile juice acts on fats. HCl is not an enzyme, it is an acid. Pepsin digests proteins.
So, the correct answer is option A.
Question 10
1 / -0

All of the following is true about the digestive system, except

A
Digestive enzymes from the pancreas are released via a duct into the duodenum.

B
Peristalsis is a wave of smooth-muscle contraction that proceeds along the digestive tract.

C
In the small intestine, villi absorb nutrients into both the lymphatic and circulatory systems.

D
The low pH of the stomach is essential in order for carbohydrate digestive enzymes to function.

E
The release of bile from the gallbladder is triggered by the hormone cholecystokinin.

Solution

The saliva contains an enzyme called salivary amylase which initiates breaking down of starch into maltose. The complete digestion of carbohydrate occurs in small intestine by pancreatic amylase. The activity of both of these enzymes is affected by pH. Salivary amylase requires pH of 6.5 to 7 to function while the enzymes in small intestines require pH around 7.5 for functioning well.
So, option D is the correct answer.
