Mutations are like genetic mutations. Say a bird species may usually have a orange beak but one bird was born with blue, that’s a mutation.
Adaptations are things you adapt to like plant species have adapted over the year to receive less and less water to live.
Natural selection is basically ‘killing off’ the weaker ones. Say a bird species has broad wings but mutations happened over time leading them to have small wings that do not allow flight, they may eventually all die off due to that. Extinction is if al those birds were to die off from that mutation.
I think the answer is scientific research sorry if I’m wrong
You are familiar with the electron transport system in photosynthesis
that takes light energy and converts it to chemical bond energy in the
form of ATP and NADPH. This electron transport chain in cellular
respiration will take the energy stored in NADH and FADH2
during the Krebs cycle and convert it to chemical bond energy in the
form of ATP. In eukaryotes, this reaction takes place on the inner
mitochondrial membrane, as is shown in Figure 4.26. Prokaryotes that
undergo aerobic respiration also have an electron transport chain
located within their plasma membrane, which may be highly folded similar
to the inner membrane of the mitochondrion. Thats the answer my friend hope it helps
