Let's do this by process of elimination: A cannot be the answer because glucose is broken down, not built up or synthesized. B is ruled out for the same reason. D is incorrect because transpiration results in water loss, not energy gain. The only correct answer choice is C respiration, specifically by the process of substrate-level phosphorylation during glycolysis in order to break down glucose into two pyruvate molecules and two net ATP
The answer I believe would be talking to plants may or may not helps plants grow faster because the amount of water given was likely different for each group. I say this because there are more than one manipulated variables. (Each experiment should only have one manipulated variable to really be able to come to a conclusion) The student wants to see if talking to the plant will help. But the student also used different watering methods. So there was more than one manipulated variable. This can not give a good enough result because we do not know which affected the plant- the talking or the watering method/amount.
Hope this helps!
Can u plz mark me as brainliest?
it allows for nutrients to come into the cell using passive tranport aka moving anything on a gradient without the use of energy (ATP).
Answer:
Independent is hormone and dependent is the weight
