All medical research is carefully planned, and this includes medical
research with animals. Experts who review a scientist’s proposed
experiment involving animals weigh several considerations before
approving each study.
The most important thing is that the research must be relevant
to human or animal health. Studies need to protect the animals’
welfare. That means that only the fewest number of the most
appropriate species may be used. Under federal law, all animals

Answer:
There is no short answer.
Explanation:
The chlorophyll is the pigment that gives the plants' leaves their green colors and it is also responsible for the photosynthesis process which takes place in the mitochondria. In the fall as the leaves change color, the amount of chlorophyll decreases and this impacts the mitochondria as it also decreases the amount of work the mitochondria does.
