Which of the following statements apply to the variation in human skin color? select all that apply. select all that apply. human skin color variation evolved recently in hominid evolution, once some populations of our human ancestors migrated out of africa. variability in human skin color can be explained by the activity of a single gene. the color of human skin and the skin of our closest primate relative exhibits a similar range in variability. human skin color variation is primarily determined by the type and amount of melanin pigment in the skin. human skin color variation likely evolved in response to differences in the intensity of sunlight around the world.

The correct answers are:

Human skin color variation evolved recently in hominid evolution, once some populations of our human ancestors migrated out of Africa.

Human skin color variation is primarily determined by the type and amount of melanin pigment in the skin

Human skin color variation likely evolved in response to differences in the intensity of sunlight around the world.

A skin pigmentation of an individual is under the influence of both:

•Genetics-individual's parents' genetic makeup,  

•Environment-exposure to sun.

Human skin color evolved by a process of natural selection in order to regulate the amount of ultraviolet radiation that penetrates the skin.

Pigment responsible for skin color is melanin, produced by skin cell-melanocytes through the process of melanogenesis. Melanogenesis is initiated by exposure to UV radiation, which causes the skin to become darker.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

it creates acid rain
