All the statements provided are true regarding frog skin. The dermis indeed contains chromatophores, which are responsible for the skin coloration in frogs. The dermis also contains large serous glands that produce skin poison, which is a defense mechanism against predators. The epidermis of frog skin contains keratin, although it is not as thick or as prominent as in the skin of terrestrial animals. Lastly, the epidermis has mucous glands that secrete mucus, which helps to keep the skin moist and aids in the process of cutaneous respiration, which is vital for frogs as they breathe through their skin as well as their lungs.
