Answer: Question 1 answer: Skin cells continually replicate

Explanation: The cells in the superficial or upper layers of skin, known as the epidermis, are constantly replacing themselves. This process of renewal is basically exfoliation (shedding) of the epidermis.

Question 4 answer: The ability to reverse terminal differentiation might affect gene expression in a complex organism

Question 5 answer Cytoplasm replicates during mitosis
