Proud flesh is composed of?
a.) collagen fibers and capillaries
b.) collagen fibers and macrophages
c.) epithelial tissue and collagen fibers
d.) epithelial tissue and capillaries

i think the answer is a but would like confirmation

b is dominant over the allele for the white fur.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
