1 Answer

(D) is the right answer.

A frog's color comes from layers of chromotophores, or pigment-containing and light-reflecting cells between the dermis and epidermis. They are controlled by hormones. he primary hormones involved in regulating translocation appear to be the melanocortins, melatonin, and melanin-concentrating hormone (MCH), that are produced mainly in the pituitary, pineal gland, and hypothalamus, respectively.Numerous melanocortin, MCH and melatonin receptors have been identified in frogs.
