The top 5 are easy loooooookkkkkk on the map D is de pere
If the body loses a substantial amount of fluids and salts and they are not quickly replaced; for example: by drinking, the body starts to "dry up" or get dehydrated. Severe dehydration can cause death. The usual causes of dehydration are a lot of diarrhoea and vomiting
B. New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.
Explanation:
The correct statement from the given choices is that new compounds with lower-energy bonds must be formed when the high- energy bonds in the food molecules are broken down.
Cellular respiration is classified as an catabolic process in which an energy rich substance is broken down into a lesser one.
- Metabolic processes are usually divided into catabolic and anabolic processes.
- In catabolic step, energy is broken down.
- Cellular respiration is catabolic whereas photosynthesis is anabolic.
- The new compounds formed have lower energy bonds after respiration.

Explanation:
What preventative measures can I take against the coronavirus disease?
The photosystems are sets of chlorophyll molecules and other pigments and transmembrane proteins packed in the thylakoids, the transfer of electrons from the primary electron acceptor of photosystem II to the P700 chlorophyll a molecules of photosystem I is called photophosphorylation.
<h3>What is photophosphorylation?</h3>
It is the global process of transformation of the energy stored in the electron of the reactive center excited by light, in a pyrophosphate bond of an ADP molecule.
When a photon is absorbed by one of the pigments of photosystem II, it quickly bounces off the other molecules until it reaches chlorophyll a in the reaction center.
The electron, after leaving photosystem II, reaches the reaction center of photosystem I, where chlorophyll P700 is, the pigments absorb light and the electron reacquires a high level of energy.
Therefore, we can conclude that when this molecule absorbs light energy, an electron is thrown up to a higher energy level and transferred to another molecule, a primary electron acceptor.
