Answer:
Letter C
Explanation:
Salmon have a physiological adaptation that allows osmoregulation to occur in two different environments (seawater and freshwater). There are specific molecules in the salmon gills that "pump" and "remove" Na and Cl ions. When at sea these molecules pump the ions out of the salmon's body and into freshwater, the same molecules remove Na and Cl from the water bringing it into the animal's blood.
A testable question is something you need data for, ex: if i bounce a bouncy ball from larger heights, how high will it fly? it can't be just a regular yes or no question

Answer:
Fasting can definitely raise blood glucose. This is due to the effect of insulin falling and the rising counter-regulatory hormones including increased sympathetic tone, noradrenaline, cortisol and growth hormone, in addition to glucagon. These all have the effect of pushing glucose from liver storage into the blood. This is normal. If you are not eating, you want to use some stored glucose. The question is this – if you are not eating, and your blood glucose went up, where did that glucose come from? It can only have come from your own body (liver). So, it’s a natural phenomenon, and the fasting now allows your body to use some of the glucose for energy.
