Answer:
To understand the tanning process one first needs to realize that the skin is comprised of several different types of cells. Each type of cell has a specific function. The cells involved primarily in the tanning process are called melanocytes. Melanocytes are located at the base of the epidermis between the epidermis and the dermis below. Melanocytes use the amino acid tyrosine to produce melanin. This melanin leaves the melanocytes and travels up through the epidermis where it reacts with the UVA and UVB radiation through a chemical reaction darkening the pigmentation of the skin. As we already know the skin consists of three layers of tissue: The epidermis or outer layer, the dermis or inner layer and the subcutaneous layer

Answer:
C. Allantois
Explanation:
The allantois is one of the four extraembryonic membranes that develop as an out-pocket of the yolk sac. The main function of allantois is to store the toxic waste, the nitrogenous waste and protects the embryo from the harmful effects of these waste products.
The allantois is a vascularized structure and its blood vessels become the blood vessels of the umbilical cord. Later, it becomes part of the urinary bladder.
Physical change. For sure none of the others. Recently learned about it.
