I would say A) Coevolution because the two species would evolve in response to one another. Flowers and their pollinators must evolve together. For example, if the flower has a mutation that no longer attracts the bumblebees, it will not reproduce. Then the hummingbird would have to find a new food source.
Answer:
Substitution
Explanation:
Mutations can simply be defined as change in the structure of a gene. Mutation can be of different types. These include, but not limited to:
- Insertion: This involves the insertion of extra base pairs into a DNA
- Deletion: Loss of DNA section
- Substitution: When a nucleotide base gets substituted with another base.
<em>Substitution of a base can lead to coding of different amino acid and hence, protein. It can also lead to coding of the same amino acid, otherwise known as silent mutation. Base substitution can also lead to the amino-acid-coding codon becoming a stop codon, leading to an incomplete protein.</em>
The correct answer is substitution.
