Answer:
The only way for gases to diffuse in and out of the leaf is though small openings on the underside of the leaf, the stomata. The stomata can open and close
Explanation:
Answer: D
They can only change one variable at a time, either water or light, not both. They could test the response to water first and follow that with an experiment for the plant's response to light. They cannot test for both at the same time.
Enzimes reduce the energy activation of a reaction
The answer is the option b, Both move molecules from higher
concentration to lower concentration.The process of diffusion is the
movement of molecules due to the difference on concentrations, which
only can occurs in one direction: from high concentration to lower
concentration. Facilitate diffusion is a specific diffusion that
happens in the cells and requires the pass through membrane cell via
transmembrane specific proteins, but that does not change the fact that
it has to be from higher concentrations to lower concentrations regions.
