Answer:
yeast can use oxygen to release the energy from sugar (like you can) in the process called respiration
two main stages are: mitosis, cytokinesis.
As the saying goes, the mitochondria are the power house of the cell. They will be supplying the energy to the cell, which they get from food.
Hopefully, this helps! =)
I think it's false. For example, when tectonic plates shift/meet, it causes an earthquake. Earthquakes can cause serious damage, (like trees falling, water ending up where it shouldn't be, animals' habitats being disturbed, etc.), so I would say that it's false that the climate is not directly effected by the movement of tectonic plates because it effects it greatly. Hope I helped! :)
