Answer:
A) Divergent evolution because all of the species have similar structures during the first stage of development.
Explanation:
Natural selection<span> is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.</span>
<span> When a cell membrane becomes energized due to electron transport reactions by the electron carriers embedded in it then this results in proton motive force (PMF). This way the cell becomes a tiny battery. </span><span>
The proton motive force (PMF) is driven by </span>the difference in charge across the plasma membrane with protons outside the membrane.
