Which is true of the population shown in this graph? a. the population is not changing much over time. b. there are many factors at work to control the population. c. the population is growing unchecked. d. the population has increased until it reached its carrying capacity.

Ok so let's eliminte some options

A populatin is not changing
this is untrue since the graph is growng (going up)

B. many factors to controll
we don't see a bumb or nick in the curve so I don't think that there is controll (exponential function)

C. population is growing unchecked.
I would agree with this option since it is just a curve without any bumps or nicks or going downs or wiggles

D. increased till it reached its carring capacity
if this was true, the graph would flatline at a certain point. this is not the case

the answer is C

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.
