Question 5
pantera1 [17]

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.

lord [1]
<h2>Competitive exclusion principle.</h2>

Explanation:

The fundamental and realized niches of B. balanoides are identical, but the fundamental and realized niches of C. stellatus are different.

All the possible combination of resources and condition under which a species can grow, survive and reproduce is called its fundamental niche. Whereas, the more limited set of resources and condition under which a species can grow, survive and reproduce in the presence of competitors and predators is termed as its realized niche.

Competitive exclusion principle states that if two competing species coexist in a stable, homogeneous environment, then they do so as a result of differentiation in their realized niche.

<em>B. balanoides</em> can use a wider range of resources than<em> C. stellatus </em>because its fundamental and realized niches are identical . Hence thrives to exclude C.stellatus.
