Answer:
The solubility of a gas in a liquid occurs faster if the liquid is cooled. Hence the correct answer is option B.
Explanation:
The solubility of a gas in a liquid occurs faster than a solid. Solid solute takes much time to be dissolved in a solvent. This is because of the bonding. The bond of the solid is is much stronger when compared to the gaseous state. This is one of the reasons of gaseous dissolving faster than solid.
A gaseous state is defined as a material whose atoms are not closely attached with one another and is free to move in any direction. And when we have to mix gas in a liquid in a faster rate the liquid temperature should be lowered.

The answer is B, How does gravitropism affect plant growth?
Explanation:
According to Google:
"Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant or fungus in response to gravity pulling on it."
So, since the students put the pots on their sides, and they say that the bean plants bend upwards, then option B is the only logical explanation for the plants' behavior.

B. VESSELS, HEART, CIRCULATING FLUID.
Explanation:
Blood is the circulating fluid. It is the connective tissue of liquid plasma and cells.
Heart is a muscular pump to move the blood and have it circulate throughout the body of living animals.
Blood vessels are arteries, capillaries and veins that deliver blood to all tissues.
The Circulatory System has two types. They are the open circulatory system and the close circulatory system.
An open circulatory system is one where the blood does not circulate inside blood vessels but also flows into cavities that irrigate tissues.
A close circulatory system is one where the blood circulate only inside the blood vessels.
