The correct answer I believe is C, but please correct me if I’m wrong!
Answer:
An example that is not mentioned would be when plants give off oxygen because oxygen is vital to keep living things that require it, alive.
Explanation:
Based on the mutation rate of the molecular clock, it will take 22.5 million years for one full base pair mutation to occur.
<h3>What is a molecular clock?</h3>
A molecular clock is a biomolecule which is chosen to serve as a clock due to its periodical changes in a regular pattern.
Mutation in genes can serve as molecular clock.
The mutation in the gene of coding for the venom mutates at a rate of 0.76 base pairs every 17.1 million years.
It will take 17.1/0.76 = 22.5 million years for 1 base pair to mutate.
Therefore, it will take 22.5 million years for one full base pair mutation to occur.
