A single base substitution mutation will be the least likely to cause a deleterious effect when the base change produces the same amino acid as the original.
<h3>What is a silent mutation?</h3>
- This scenario is what we call a silent mutation.
- What this means is that the mutation is almost undetectable due to its not affecting the protein that it will help to form.
- This is possible thanks to how the genetic code operates, <u>different codons are able to code for the same amino acid.</u>
- Therefore, there are mutations that do not affect the amino acid or the protein.
Therefore, we can confirm that a mutation will have no negative effects if it is a silent mutation, meaning that the substitution of a base pair happens to code for the same amino acid as the original.

Answer: Option C) increased rate at which carbon dioxide is extracted out of the atmosphere
Explanation:
Deforestation refers to the falling of trees. Now, since plants including trees rely on the atmosphere for their supply of carbon dioxide (CO2) to make food, their absence would rather make more carbon dioxide present in the atmosphere.
Thus, increased rate of carbon dioxide extraction from the atmosphere is not an effect of deforestation.
Answer:
Mesophyll cells.
Explanation:
Transpiration is the evaporation of water at the surfaces of the spongy mesophyll cells in leaves, followed by loss of water vapour through the stomata . Transpiration produces a tension or 'pull' on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled up through the plant.
