Answer: 1.  Human skin color variations are primarily being determined by the type and amount of melanin pigment which is the skin.

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

3.Human skin color variation evolved recently in hominid evolution.

Explanation:

1. Human skin color variations are primarily being determined by the type and amount of melanin pigment which is the skin.

Melanin is the basic determinant of skin color. The actual skin color of different humans is affected by the pigment melanin. It is produced within the skin in cells called melanocytes. The concentration of the melanin produced in the skin may vary among the ethnic groups or from individual to individual. Hence, the color of the skin may vary from light to dark.

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

The intensity of sunlight may vary all over the world. The sunlight energy is absorbed by the melanin pigment present in the melanocytes of the humans. Therefore, intensity of sunlight as well as the concentration of the melanin both are responsible for imparting color variation in humans.

3.Human skin color variation evolved recently in hominid evolution.

Human skin color variation was evolved in response to differences in intensity of sunlight around the world. The early human species is expected to be evolved from Africa which exhibit high intensity sunlight.

<span>Human skin color variations are primarily being determined by the type and amount of melanin pigment which is the skin.

The reason is the amount of melanin present, pigment present which determines the color of skin the more the melanin the more dark color they are.

Human skin color variation is likely evolved in response to differences in intensity of sunlight around the world. Reason being it has been developed because of different exposure of humans to the varied environment during migration. Human skin color variation evolved recently in hominid evolution.</span>

Hint:think about the direction of movement caused by stress
Shkiper50 [21]

Answer:

Compression is a reverse fault, tension is normal fault and shear is strike slip fault.

Explanation:

Compression is a reverse fault, tension is normal fault and shear is strike slip fault. Reverse fault is opposite of normal fault which occurs due to the stress of compression on an object in which both object come close together. Due to tension stress, rocks pulling apart from each other, produces a normal fault. Shear is strike slip fault because in strike-slip fault, the two blocks slide over one another
