The correct options are as follows:
1. Human skin color variation is primarily determined by the type and amount of melanin pigment in the skin.
2. Human skin color variation likely evolved in response to differences in the intensity of sunlight around the world.
3. Human skin color evolve recently in hominid evolution, once some population of human ancestor migrated out of Africa.
The color of human skin is primarily determine by melanin. The intensity of the sun in the climate where one is living also affect the type of skin color that will dominate in a geographical area.
Answer:
dioxide and water.

The carbon comes from carbon dioxide which is used during photosynthesis.
During the process of photosynthesis, most plants get the sun's energy into chemical energy which is also captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.
The false answer is B because to be exact, the two copies of a gene carried by an organism (such as a Y and a y allele) are located at the same spot on the two chromosomes of a homologous pair. Homologous chromosomes are similar but non-identical, and an organism gets one member of the pair from each of its two parents.
