True, this is exactly what convergent evolution is
According to the research, the primary purpose of membrane channels is to circulate ions, and of membrane pumps is to maintain differences in ionic concentration.
<h3>What are membrane channels and pumps?</h3>
They are pores in the cell membrane through which ions circulate for muscle contraction or membrane potential changes that may depend on a ligand or voltage, depending on whether their opening is determined by the binding of a ligand or by changes of voltage.
In this sense, membrane pumps is the mechanism of active ion transport, consuming energy across a membrane against an electromechanical gradient to maintain differences in ion concentration between the intracellular and extracellular space.
Therefore, we can conclude that according to the research, the primary purpose of membrane channels is to circulate ions, and of membrane pumps is to maintain differences in ionic concentration.

Answer: Increased pressure gradient
Explanation:
The movement of gas takes place by the help of diffusion. The pressure is established in between the two different types of gases.
The movement of gas from higher concentration to lower concentration will take place when a pressure gradient is established in between them.
So, if there is an increased pressure gradient between oxygen and carbon dioxide then gaseous exchange will take place.
Answer:
B
explanation:
because the movement of the carbon from the atmosphere to the lithosphere began with rain
The answer would be C. Thomas Hunt Morgan continued the genetic research of Gregor Mendel, but Morgan used fruit flies.
