The right answer is the catalyst.
In chemistry, a catalyst is a substance that increases the rate of a chemical reaction; it participates in the reaction but it is neither part of the products nor reagents and therefore does not appear in the equation-balance of this reaction.
The catalyst accelerates, sometimes in considerable proportions, the chemical reaction, but it is not consumed: either it does not participate in the reaction but its presence facilitates the breakage of the bonds, or it participates but is regenerated at the end.
Catalysts are widely used in industry and laboratory.
In nature and in biochemistry, some proteins have catalytic activity. They are enzymes.
Answer:
Resting potential is when there are more positively charged ions outside the cell than there are inside the cell, and this is the regular state.
Threshold potential is when there is a triggering event that depolarizes the cell body, where positively charged ions enter the cell body at a rapid rate.
Depolarization is when the membrane potential gets smaller, and the cell begins to equalize itself on the inside and out. Positively charged ions enter the negatively charged axon, resulting in the cell being positively charged.
Repolarization brings the cell back to its resting potential - the ion gates of the cell close, keeping the positively charged ions out, while the potassium gates remain open.
B. bacteria and plants.
C. animals performing respiration.
D. plants performing photosynthesis.

B. Bacteria and Plants
Explanation:
Answer:
If a foreign mountain lion species is introduced into the ecosystem then it can affect the ecosystem in any way. Lion is a top carnivore which eats the small animals present in the environment.
There are chances that the lion might substitute the other predators present in that region.
There are chances that the ecosystem may maintain the equilibrium.
