Answer:B is the right answer I am sure.
Explanation:
Answer:
In the electron transport chain, when the protons move down their concentration gradient, the electrons are transferred from one molecule to the other and energy is released.
Explanation:
During the rear stage of cell respiration or oxidative phosphorylation two processes are involved. Among which one is the electron transport proton gradient chain, in which protons are transferred from one to the other molecule.
In this process electron also releases energy to make an electrochemical gradient. In this chain oxygen accepts protons and chooses electron to produce water.

A fish. Fossilisation requires very specific set of conditions - the creature in question has to have hard parts to be preserved, then it must die and end up somewhere where it won't be eaten or disturbed, it must be Anoxic so it won't decompose normally, it must be buried.
The fish has a bony skeleton, lives in the ocean. So, it may die, sink to the anoxic bottom part of an ocean/lake, be covered by sediment and maybe become a fossil, if nothing disturbs it.
Happy Studying!
