Explanation:

Question 52

Healthy skin's surface has a slightly acidic pH (around 4.5 - 5.5) due to the acid mantle, which helps protect against pathogens. Option a (alkaline) is incorrect as skin isn't alkaline. Option b (yellow) is incorrect as healthy skin isn't typically yellow (unless with conditions like jaundice, which is abnormal). Option d (rough) is incorrect as healthy skin is smooth. So the correct answer is c.

Pediculosis capitis is the medical term for a head lice infestation on the hair and scalp. Option a (Pediculosis furuncle) is incorrect (furuncle is a boil). Option b (Alopecia areata) is hair loss, not lice. Option d (Vesicles parasites) is not a standard term for head lice. So the correct answer is c.

The three growth cycles of human hair are anagen (growth phase), catagen (transition phase), and telogen (resting phase). Option a has a redundant "growth phase" (anagen is the growth phase). Option b's "mature" is incorrect. Option c's "return" and "transition" are incorrect. So the correct answer is d.

Answer:

c. acidic
