Does health insurance system in the US affect the work of health scientists? Why or why not?
notka56 [123]

Answer:

pretty sure that health scientists, assuming they understand pharmaceutical actions and reactions, get paid either way & possibly get cheaper h insurance for their expertise.

Explanation:

No, does not affect their work because they get paid to test new drugs on lab rats, chimps, dogs, etc. to see if there is an effect on subjects they give a medical condition to. As unfair as it seems, once lab subjects are tested for years, and they witness if they're theories are justified or not; then they determine a trial run on human test subjects. this process can take up 2 10 years or longer.

What is present on all skin surfaces except on the palms, soles, lips, and parts of the external genitalia
KIM [24]

Sebaceous glands are present on all skin surfaces except on the palms, soles, lips, and parts of the external genitalia.

Sebaceous glands are part of the pilosebaceous unit. There are generally numerous sebaceous glands per each hair follicle. Sebaceous glands are true exocrine glands made up of lobules and ducts.

The lobules are made up of sebaceous cells which produce sebum, a fatty substance that lubricates hair and has bactericidal and fungicidal properties.

These sebaceous or oil glands are also classified as holocrine exocrine glands. It means that the entire sebaceous cell loses its cytoplasm and dies in the process of discharging its contents during the excretory process toward the middle of the gland into its lumen.
