Answer:
some of it I believe is the correct answer for that question
I am pretty sure the answer is A but i'm not sure
The stomata and their guard cells allows this happen.
Stomata is like a hole or gap on a leaf, most of them are present in a bottom side of the leaf, since waxy cuticle is not present over there. And 2 guard cells make up a stomata.
Guard cells are able to control the size of the stomata, depending on the situation. For example, the guard cells close up during day time because a lot of sunlight may cause more water loss.
In conclusion, guard cells and the stomata are the main structures that allow carbon dioxide and oxygen (water too) diffuse in and out of leaves.
Answer:
Anaerobic respiration or fermentation
Explanation:
The metabolic pathway shown in the question is the summary of anaerobic respiration (fermentation) during which pyruvate is converted to acetaldehyde, followed by the formation of alcohol (ethanol), along with the release of NADH and NAD molecules. This mechanism occurs in the absence of oxygen and is thus used by organisms to generate energy (ATP) molecules.
