Since you are trying to investigate the possible variables that contribute to reef threats, it is advisable that you do an environmental study between two reefs that have characteristics that are similar or are closely similar. With this, you will be able to identify which is the primary cause of reef threats. Thus the correct answer is B.
Answer:
The correct answer is c) They are used to form ATP by chemiosmosis
Explanation:
In cellular respiration, glucose is oxidized into carbon dioxide and water and converts into NADH a FADH₂ during glycolysis and Kreb cycle. Then these reduced molecules are used to provide the source of electrons during chemiosmosis.
This transfer of electron to electron transport chain brings the conformation change in proteins that helps in transport of H⁺ions across the inner membrane of mitochondria. This transport of ions increase the proton gradient in the membrane.
So to equalize the proton gradient H⁺ moves towards the matrix through ATPase which allows the formation of ATP from ADP. Therefore the right answer is c) They are used to form ATP by chemiosmosis.
The answer is D. Sedimentary rock takes millions of years to form since sedimentary rock is formed by sand cementing together over long periods of time.
