Explanation:

Question 42

Hematopoiesis (blood cell formation) occurs in red bone marrow, while yellow bone marrow is mainly for fat storage. So the statement is false.

The stratum corneum is the outermost layer of the epidermis, composed of dead, keratinized cells. Melanin is produced in the stratum basale and protects the deeper layers. The stratum corneum has no living cells and is least protected by melanin compared to the other layers (stratum basale, stratum granulosum, stratum spinosum which have living cells or are closer to the melanin - producing layer).

Answer:

False
