Answer: chemical reactions
Explanation: The function of an enzyme is to speed up chemical reactions. They do this by lowering the activation energy, which is the minimum energy that must be available for a chemical reaction to occur. If the energy required is lowered, the reaction can go faster.

A way in which models cannot be useful is: B). being a perfect representation of a situation.
<h3>What is a model?</h3>
A model can be defined as the creation of a physical object either from kits, components or other applicable materials that are acquired by the builder, so as to simulate a phenomenon or process.
This ultimately implies that, a model should be probabilistic in nature rather than being perfect, so as to effectively illustrate or describe the relationship that is existing between an independent variable and the dependent variable.
Generally, some of the ways in which models cannot be useful include the following:
- Building intuition for situations.
- Making predictions that can be verified.
In conclusion, we can infer and logically deduce that way in which models cannot be useful is being a perfect representation of a situation.

Answer:
D
Explanation:
Water and air circulate around the world in water currents and wind systems (like prevailing winds) respectively, hence distribute energy and whatever else they are carrying across the globe. This is why polluting the oceans in the equatorial region will have indirect consequences for marine life in the poles.
Pollution of air through emission of greenhouse gases in one part of the globe will contribute to global warming across the world because these emissions will be carried around by prevailing winds and diffuse across the atmosphere.
Global warming also causes climate change that subsequently causes the displacement or migration of organisms when this change in climate is unfavorable
