Do people perform better on exams when they wear their favorite color ?

A. The question is not specific.

B. The question reflects an opinion.  

C. The question can be tested by a systematic procedure.

D. The question asks about phenomena that cannot be measured.

Correct answer choice is:

A scientific question is a problem that may point to a hypothesis and support us in solving the cause for any research. A good scientific question has several aspects. It should have any true results, should be testable.

A systematic process is usually intimately connected with the decisive study. In common, the purpose of a systematic process is viewed as a mechanism of control directed at decreasing the number and austerity of errors, omissions, and failures due to both human or technological functions associated.

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.
