Leaves of a healthy potted plant were coated with Vaseline to block the stomata will this plant remain healthy for long.

No. when stomata is blocked, photosynthesis will stop because the CO₂ level will decline within the leaf, stopping the reactions that are light-independent.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
