Answer:
It has no atmosphere.
Its surface is covered with circular craters.
It has huge, round basins.
It has lunar highlands.
Explanation:
Mercury is similar to the moon because both have no atmosphere, surface is covered with circular craters and having large, round basins. Both have lunar highlands. Craters are the circular, excavated holes made by impact events that has a rough surface while on the other hands, most of the crust of the Moon is made of silicate rocks is known as anorthosites, these regions are called the lunar highlands.
Provides evidence of evolution and can classify species and find common relatives
Homeostasis involves maintaining balance of several factors that make a cell healthy. The job of the cell membrane is to regulate the passage of materials into and out of the cell. In order for any materials to go in or out of the cell, they must cross through the cell's membrane.

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.
