Explanation:
Answer:
macroevolution or microevolution
Answer:
B. MacConkey is both a differential and a selective medium.
Explanation:
Selective media contain the ingredients that allows for the growing of specific microbes while inhibiting the others.
For example MacConkey media facilitate the growth of gram negative bacteria and inhibit the growth of gram positive bacteria. That why E. coli and P. mirabilis grew on the media because these are gram negative and S. saprophyticus does not grew being gram positive.
Differential media allow to differentiate between selected microbes by visual observation.
For Example MacConkey media differentiate between organisms that can ferment lactose to the organisms that can't ferment it. That why E. coli appeared pink on the media because it can ferment lactose while P. mirabilis appears colorless because it usually cannot ferment lactose.
If the coyote population decreases then the pika population will increase due to their main threat decreasing. (basically with no one to eat the little guys they will be able to have ALOT of babies)<span />
Fires in grasslands prevent the growth of shrubs. Plants can survive in these fires because most of them have parts underground, where fire cannot reach. Animals and runners aren't affected by this, because they can leave.
