DNA replication is the process of copying a double-stranded DNA molecule. Both strands serve as templates for the reproduction of the opposite strand. The process is sometimes called "semi-conservative replication" because the daughter DNA from the original parent strand contains half of the original and half of the newly synthesized DNA.

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.
The answer is A. Ethical Behavior

The Himalayan rabbit's environment entirely determines the color of its coat.
<h3>How does the environment affect the coat color on the fur of a Himalayan rabbit? </h3>
The color of newborn Himalayan rabbits is either white or light grey. Beginning at the age of four weeks and ending at six months, coloring the coat is a process. The temperature of the environment affects the color of the coat, which grows darker in colder climates and lighter in warmer ones. The Himalayan rabbit's hair turns black when it is subjected to subfreezing conditions. That area's fur finally turned black. The rabbit's newly grown fur will be black in color if the white fur is removed and the animal is kept at a low temperature. Considering this, it is clear that temperature affects the expression of genes that control this organism's fur color.
