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

<h3> How do whitehead and blackhead form?</h3>

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:

<h2>Option A is the correct answer. </h2>

Explanation:

<h2>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.</h2>

5. Calculating
Irina18 [472]

Answer:

The convergent boundary moves 0.00901° or 32.4" in terms of latitude change for a 1 km northward distance change.

Explanation:

With the question 4 and the answer to question 4 missing from this question, the solution will be provided with just the information provided in this question.

A change in latitude of 1 degree corresponds to an approximate 111 km distance along a north-south line.

1° latitude change = 111 km distance along north-south line

The convergent boundary moves 1 km northward. We can calculate how much of a change that is on the latitude.

111 km = 1°

1 km = (1×1/111) = 0.00901°

Converting to seconds, the convergent boundary moves (0.00901 × 3600)" = 32.4" in terms of latitude change.

Hope this Helps!!!
