Answer:
Why is healthy skin important? Healthy skin is important because it is your first line of defense against bacteria and other pollutants in the environment. Healthy skin is more resilient when faced with external stresses, serves as an important sensory organ and helps to regulate our body temperature.
The outermost layer of skin, called the epidermis, produces a thin barrier layer called the stratum corneum. This layer varies throughout the body in its structure, thickness, composition and functional properties. For example, the skin on your palms and soles is thicker than on your face.
Skin changes such as wrinkling are one of the physical alterations most readily associated with aging. It may surprise you that the outer layer of the skin, the stratum corneum, changes very little as we age. The main changes occur at a deeper level. Collagen, a basic chemical building block of skin and connective tissue, decreases with age.

The ABO blood group classification is based on antigens on red blood cells and antibodies found in blood plasma.</span>Blood type A has antigen A on the red blood cells and anti - B antibodies in the blood.Blood type B has antigen B on the red blood cells and anti - A antibodies in the blood.Blood type AB has both antigen A and B on the red blood cells but has no anti-A nor anti - B antibodies in the blood<span>Blood type O has no antigen on the red blood cells and has both anti -A and anti B antibodies in the blood.</span>
I thinking the answer was for some genes, both alleles express together. Others combine to give an average phenotype....
I’m assuming you mean if the sun dies out. If so, then most things on earth would die within a few days due to lack of photosynthesis and to freezing temperatures (which is what would cause humans to die).
Because these non native species can cause competition for the same food source as the native species thus making it harder for the native species to survive. Also the non native species could see the native species as food causing them to die out. As well as introducing new diseases that these native species don’t know how to defend themselves from
