Answer 1

There are different reasons for formation off things. The blackheads are formed when sebaceous glands become clogged.

How do whitehead and blackhead form?

When sebaceous gland's duct is known to be blocked by sebum, a whitehead is therefore seen or show forth on the skin surface.

When the built up material oxidizes and dries, it therefore darkens, and then create a blackhead.

Answer 2

Answer:

Option A is the correct answer.

Explanation:

Blackheads form when a hair follicle in the skin becomes clogged or plugged. Dead skin cells and excess oil collect in the follicle's opening, which produces a bump. If the skin over the bump opens, the air exposure causes the plug to look black, thus forming a blackhead.
