Answer:
D. cell is the smallest part of an organism.
as cell is basic functional and structure of life.
DNA replication occurs due to an enzyme. The DNA unzips, and the enzyme pieces together new parts to make each half its own full DNA strand.
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:
electrical signals
Explanation:
As the light hits our eyes, it passes through the lens and goes to the retina where it gets converted to electrical signals. It travels to the optic nerves, then to the brain which will produce an image for you to see.
