I think the correct answer is ions.
An action potential occurs when a neuron sends information down an axon, away from the cell body. A neuron that emits an action potential, or nerve impulse is said to fire. These action potentials are generated by special types of voltage hated ion channels that are embedded in the plasma membrane of the cell.
In a particular context, “epoch” can refer to a particular point of time characterized by a particular event/series of events.
While “era” refers to a period of time characterized by events in a chronological order.
Thus, an “era” can encompass more than one “epoch”.
“Period” can refer to a short interval of time or a very long interval of time.
For example:
<span>“My period of happiness….”“The period of Four Horsemen…”</span>
<span>“Eon” </span>refers to an indefinitely long time. <span>Eon is presumed to consist of at least 2 eras.</span>
Phylogenetic tree is the evolutionary tree that shows the inferred evolutionary relationships among various biological species and organisms. <span>Phylogenetic relationship” refers to the relative times in the past that species shared common ancestors.</span>
According to the phylogenetic tree diagram, modern birds are most closely related to an advanced dinosaur.
The altered protein affected the function of the cell membrane. The cell membrane which contain a bilayer control the movement of substance in and out of the cell and organelles. Due to this it is selective permeable to ion and organic molecules.
Yeah it haves to be C if not then it could be b I think but I probably more positive with c
