Cells undergoing chemotaxis rely on the process of accommodation to keep moving towards higher concentrations of attractants. what protein is directly responsible for modifying the mcp and causing accommodation?

CheR is the protein responsible of  for modifying the MCP and causing accommodation. When cells undergo chemotaxis.

Explanation:

Chemotaxis is the movement effect a certain organism suffers after being exposed to chemical stimuli. The organisms that react like this are somatic cells, bacteria, single-cell, or multicellular organisms. Now, when these organisms are in the regulation phase they accept CheR to modify the Mcp or methyl-accepting chemotaxis proteins. The McP is modified because it is needed to regulate the number of proteins required to move and maintaining the number of proteins high but not over administered. Thus, to be capable o performing chemotaxis at its most optimate level at any time.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

air enters through the nose, moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi andbronchioles till the alveoli.
