Answer:

Oxygen

Explanation:

Oxygen is the by product of photolysis during photosynthesis whereby water molecules are split to form protons (H+ ions), electrons and oxygen (by product).

Oxygen is not needed during any of the reactions in photosynthesis and Calvin cycle and will not affect the rate of photosynthesis or possibility of photosynthesis occurring. However, it will affect the process of aerobic respiration instead.

Carbon dioxide is needed in carbon fixation during the Calvin cycle. Without it, 6 carbon sugars cannot be formed.

Water is needed for photolysis to produce protons (maintain the electrochemical gradient) and electrons (to replenish lost electrons)

Chlorophyll are pigments that harvest light energy to excite electrons produced from photolysis of water to be passed down the electron transport chain.

Light is needed as a source of energy to energise the electrons

Adrenaline is a stress hormone secreted by the adrenal glands and some other neurons when a person is frightened, excited or generally in stress.

It prepares our body for it's 'fight or flight' mechanism and tightens muscles for exertion.

How are scientists able to observe, record, study, and predict changes in the earth
Luba_88 [7]

ANSWER:

Its because mother nature tells us herself!

its just like predicting when rhinos will go instinct:

imagine people killing 2 rhinos a week or every two weeks and theres only 500-1000, you can predict that in prob 3-5 years they'll go instinct

so its just like that and they have much higher technology now that it'll just give them the answer without putting much effort into it.
