Answer:
The correct answer is - tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.
Explanation:
In freshwater fishes, the body of fishes has a higher salt concentration inside their body than the surrounding water, water enters through the osmosis process. Without any active regulation of this process, fishes would swell and get bigger and bigger. They have specialized cells called chloride cells in gills to take ions from water as they do not have kidneys.
In contrast, the marine fishes have a lower salt concentration in their body than surrounding water of sea or ocean and they lose water continuously and to compensate for this they need to drink water regularly.
The answer is D . Pressure causes water and dissolved substances to filter though capillary walls of the glomerulus .
Phosphoryl-transfer potential is the ability of an organic molecule to transfer its terminal phosphoryl group to water which is an acceptor molecule. It is the “standard free energy of hydrolysis”.
Explanation:
This potential plays a key role during cellular energy transformation by energy coupling during ATP hydrolysis.
A compound with a high phosphoryl-transfer potential has the increased ability to couple the carbon oxidation with ATP synthesis and can accelerate cellular energy transformation.
A compound with a high phosphoryl-transfer potential can readily donate its terminal phosphate group; whereas, a compound with a low has a lesser ability to donate its phosphate group.
ATP molecules have a high phosphoryl transfer potential due to its structure, resonance stabilization, high entropy, electrostatic repulsion and stabilization by hydration. Compounds like creatine phosphate, phosphoenolpyruvate also have high phosphoryl-transfer potential.
