Aplasia: a = without; plasia = growth/formation8. Abscission: ab = away from; cission = cutting9. Excise: ex = out; cise = cut10. Debridement: de = away; ment = action
Answer: A gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. A chromosome is a long DNA molecule with part or all of the genetic material of an organism. A allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

I want to say that the answer is A
The question is incomplete. The complete quesetion is:
The outer layers of human skin are composed of dead cells impregnated with keratin and oil, which make the epidermis relatively impermeable to water, yet humans sweat freely in hot temperatures. This occurs because:
a) the salt in sweat allows it to diffuse through the skin.
b) sweat glands have special channels through the skin.
c) an osmotic gradient in sweat moves it through the skin.
d) sweating occurs in only those areas of the body where the skin is water permeable.
Answer:
b) sweat glands have special channels through the skin.
Explanation:
Sweat glands are present in the reticular region of the dermis. This part of the dermis contains bundles of thick collagen fibers, fibroblasts, and various cells. Sweat glands are present between these fibers. The ducts of sweat glands open on the tops of the epidermal ridges as sweat pores to release the secretions of the gland outside. This is how irrespective of the presence of the keratin layer on the outer surface of the skin, it releases sweat in hot summer days.
It is a<span> semi-permeab</span>le / selectively permeable membrane that can be attributed to the cell's ability to controls the traffic the flow of molecules into and out of the cell, to prevent the entry of toxic materials into the cell and to permit selective uptake of nutrients.
