Cells<span> need a source of </span>energy<span>, they </span>get<span> this </span>energy<span> by breaking down food molecules to release, the stored chemical </span>energy.This process is called 'cellular<span>respiration'. The process is happens in all the </span>cells<span> in our body. Oxygen is used to oxidize food, main oxidized food is sugar(glucose).</span>
The main reason for this activity is the activation energy needs to be overcome in the reaction.
<h3>What do you mean by Dehydration?</h3>
Dehydration may be defined as a process where there is a removal or loss of water takes place from something.
When the reaction between sucrose and and sulfuric acid is carried, it may leads to dehydration of sucrose. As a result of this, activation energy requires to come up in the reaction.
Therefore, the main reason for this activity is the activation energy needs to be overcome in the reaction.

Answer:
The correct option is A) will make no difference in the survival of life if there were major changes in the environment.
Explanation:
Due to genetic diversity, variations in species are caused which makes some organisms of a species to be better adapted than other members of the species. These variations cause organisms to survive when differences in the environment occur. Although the allele frequencies might change due to the changes in the environment but the phenomenon of genetic diversity allows life to sustain on earth even when conditions will become unfavourable.
I’m not sure but I think DNA
