D. is the heterotrophism hypothesis, but it is questionable that it is the "strongest" hypothesis. The alternately proposed option is autotrophism, which is the ability of an organism to obtain its own nutrients without relying on other organic materials. The potential advantage of autotrophism is its relatively simpler structure, making a simpler organism viable because it is potentially less complex and "easier to create."

Sergio039 [100]

Answer:

The correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.

Explanation:

For the majority of the solids dissolved in water, the solubility increases with temperature increments. Higher temperatures accompany the increase in kinetic energy permits the solvent particles to more adequately break apart the solute atoms that shows intermolecular attractions.

So if glass one dissolves the salt faster than glass two then it is clear that glass one has more temperature than glass two that takes more time to dissolve the rock salt.

Thus, the correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.
