Answer:

Only some species may survive the event

Explanation:

Evolution is most likely to occur when catastrophic events alter community composition. Catastrophic global event can influence that only the hardiest, generalist species may survive. Specialists may be left without food and starve.

Answer: The options are not given, here are the options.

A. One species is much better competitor than the other.

B. Periodic disturbances allow for coexistence.

C. Two species tended to use different resources.

D. The two species experienced interference competition and not exploitative competition.

The correct option C.

Two species tended to use different resources.

Explanation:

From Gause experiments on competing paramecium pairs, He found out that most times both species persisted and sometimes only one did because the two species uses different resources.

Organisms normally compete for limited resources in order to survive and one intend to compete well while other suffer. Both in the case of competing paramecium pairs, the pair use different resources which make the to persist and survive well. Once the resource of one finishes, the other one will persist because it is still surviving on its available resources.

Since both glycolysis and gluconeogenesis are irreversible processes, there is no thermodynamic barrier to their simultaneous op
luda_lava [24]

Answer:

It is not important for the cell not to run glycolysis and gluconeogenesis at high rate simultaneously because body carry out various metabolic pathaways with respect to body"s  requirement for metabolites .

Explanation:

Human bodyphysiology helps to maintain homeostasis of various metabolic intermediates within our body.

                It is not that the glycolytic intermediates and end product such as pyruvate always enter the gluconeogenesis process because pyruvate have different metabolic fates beside acting as a precursor for glucose biosynthesis.

            Cell does not require glycolytic intermediates and gluconeogenesis intermediates at the same time.

           That"s why it is important for the cell not to run glycolysis and gluconeogenesis simultaneously.

stepan [7]
