Proteins that are functionally less important for the survival of an organism generally evolve faster than more important proteins.
Proteins serve as the building blocks for all of life's essential processes. The proteins evolve along with the genes that create them, adding new functionality or features that may potentially result in the development of new species.
The mutation of amino acid-coding nucleotides and the stabilization of novel variations in the population are the two phases required for protein evolution.
The stability of a protein's folded structure, how well it prevents aggregation, and how well it is chaperoned all affect how quickly it evolves. According to the studies, the degree of a protein's expression has a greater influence on its evolutionary rate than does the protein's functional significance.

Answer:
The cells need water to maintain their metabolic functions, the way water enters through cells membranes is by osmosis.
Explanation:
The cell membrane is a lipidic bilayer composed of phospholipids and embedded proteins. Phospholipids have the characteristic of being amphiphilic which means that possess hydrophilic and lipophilic characteristics. The most common way is by osmosis, that is a mechanism that moves water from high concentration to less concentration of water. In the cell membrane, there are is channels of proteins called aquaporins that facilitate the pass of water through the membrane. Also, as water is a very small molecule without charge, this characteristic allows passing a limit amount of water molecules through the hydrophilic characteristic of membranes.

Answer:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.
Explanation:
