Question

Wearing of cartilage in the body
friction
(A) increases
(B) decreases
(C) does not effect
(D) may increase or decrease​

Answer 1

Answer:

Increases

Explanation:

Wearing of cartilage in the body increases friction.

Cartilage is responsible for smooth movement of the body. It is present between the bones so that the bones do not rub with each other. So, the cartilage is responsible for decreasing friction between two bones. In case the cartilage present between two bones wears out, then the smooth movement of two bones will not be possible. The bones will rub against each other and will ultimately break down. Hence, the wearing of cartilage will increase the friction in the body.
