Which of the following best explains the connection between increased competition and the evolution of a species by natural selection?

A) Individuals migrate to another area in order to avoid competition for limited resources in the current
ecosystem

B) Individuals that must compete for limited resources are more likely to have diseases that cause mutations

C) Individuals must become stronger to compete for resources, and this increased strength is passed on to the next generation.

D) Individuals that have traits that allow them to outcompete others survive better and produce more offspring

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.

i dont know it at allnow im just getting points at this pint

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
