C Correct answer
Explanation

Chewing of food is the process of mastication of food. It is important to break down the food mechanically by teeth so that it gets easily mixed with saliva and swallowed. The food should be chewed 20 times before swallow it to increase its surface area.

So the correct answer is '20'.

Chewing is required for

  1. Solubilisation of food

  2. Enjoying the taste of food

  3. Decreasing surface area of food

  4. Increasing surface area of food

D Correct answer
Explanation

Chewing (mastication) breaks large food particles into smaller pieces. This mechanical process significantly increases the surface area of the food, allowing digestive enzymes to act more efficiently.

The major utility of breaking up of food into small bits during chewing is

  1. To reduce surface area of the food eaten up

  2. To increase surface area of the food eaten up

  3. To make the food soluble

  4. To enjoy taste of food
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Chewing breaks the large food particles into the small. The mechanical digestion of food in the mouth involves converting bite-sized pieces of food into smaller particles. This has the effect of increasing the surface area of the food particles and allowing saliva to be thoroughly mixed with them.

So, the correct answer is 'To increase the surface area of the food eaten up'.

The fore arm has two bones.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The forearm is the region of the upper limb between the elbow and the wrist. The forearm contains two long bones, the radius and the ulna, forming the radioulnar joint. The ulna is the longer and larger of the two bones, residing on the medial side of the forearm. Compared to the ulna, the radius is slightly shorter, thinner, and extends from the lateral side of the elbow. 
So, the answer is true.

The finger bones do not have joints.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The hand and wrist are made up of many different bones, muscles and ligaments that enable a wide range of movements. Rather than a single joint, each of the fingers has three joints: Metacarpophalangeal joint (MCP)- joint at the base of the finger, Proximal interphalangeal joint (PIP)- joint in the middle of the finger and Distal interphalangeal joint (DIP)- joint closest to the fingertip. Each thumb has two joints.
So, the answer is false.

Read the following statements and find out the incorrect statement.
A. About $45-50\%$ of the body weight of a human adult is contributed by muscles.
B. Muscles have special properties like excitability, contractility, extensibility and elasticity.
C. Based on their location, three types of muscles are identified: skeletal, smooth and cardiac.
D. Based on appearance, cardiac muscles are striated. They are involuntary in nature as the nervous system does not control their activity directly.

  1. B & C

  2. A & C

  3. Only A

  4. A & D
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  1. A major bulk of body weight; 45−50% is contributed by muscles.
    2. All muscle cells share four primary properties that distinguish them from other cells : excitability, contractility, extensibility and elasticity.
    3. Based on their location, three types of muscles are identified: skeletal, smooth and cardiac.
    4. Cardiac muscles are striated in appearance and myogenic in nature.
    So, none of the given options are incorrect.

The longest bone in our body is

  1. Thigh bone

  2. Fore arm bone

  3. Sternum

  4. Girdle bone
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Femur or thighbone is the longest bone in the body. The head of the femur fits into the hip socket and the bottom end connects to your knee. The two bones beneath the knee that make up your shin are tibia and fibula. The upper and lower leg are connected by a hinge joint.

So, the correct answer is 'Thigh bone'.

The only movable part of the skull is

  1. Upper jaw

  2. Lower jaw

  3. Both A & B

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The mandible or lower jaw, is the only movable part of the skull, forming the temporomandibular joint with the temporal bone.
  • The mandible is the largest, strongest and lowest bone in the human face. It forms the lower jaw and holds the lower teeth in place.
  • So, the correct answer is 'Lower jaw'.
