Answer 1

The two basic tissues of which skin is composed are dense connective tissue, which makes up the dermis, and stratified squamous epithelium, which forms the epidermis are keratinocytes, the protein keratin makes the dermis tough and leather like. the specialized cells that produce the pigments that contribute to skin color are called melanocytes.

Four protective functions of the skin are-1) prevention of dehydration, 2)prevention of bacterial invasion 3) protection against thermal damage 4)protection against UV radiation
