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.

a classmate states that mitochondria and chloroplasts descended from the same type of bacteria. Does the evidence support this?

tia_tia [17]

The endosymbiotic theory explains that mitochondria and chloroplasts descended from the same type of bacteria. Symbiosis is an interaction between two organisms of different species, and <u>endo</u>symbiosis is a type of symbiosis in which one organism lives <u>inside </u>the other one. According to the endosymbiotic theory, a host cell ingested symbiotic bacteria, which specialized into mitochondria or chloroplasts. The evidence for this theory is that mitochondria and chloroplasts, like bacteria, have their own circular DNA. They also have their own transcriptional and translational machinery.
