Design an experiment that would increase the pH and maintain a homeostasis. You need to remember that photosynthesis is this reaction:

6CO2

6H,0 + Light CH,206 602

Carbon Dioxide Water

Glucose Oxygen

+

We can use solar powered cars or ride bikes instead of cars that burn fossil fuels

Mitochondria produce atp, a high energy compound. atp is used for all sorts of enzyme-mediated reactions, such as making proteins/nucleotides/etc, certain compounds cross the cell membrane, muscles move, etc.  without this source of energy, a cell will die. it will not be able to repair itself, defend against pathogens, etc.

Ithink its because more have died recently than in the past.
