Answer: D.) It allows water to resist freezing and thawing cycles.
The ability of the water molecule to absorb and retain heat is called as heat capacity of water, because of this property the temperature of water remains the same for long, irrespective of the external environment. It allows water to resist freezing and thawing cycles because water molecules will resist change in it's temperature. This temperature regulation will prevent instant heating and cooling, hence, will provide suitable environment for the survival of marine organisms.
In biological systems, the chemical reactions concerning glucose and ATP as a product are vital for cellular respiration and photosynthesis. Shortcuts reduce the activation energy, which increases the net "gain" of products. I would go with the last one.
The answer is A. Putting the aquarium in the dark means that
