According to the research, the correct option is hydrophilic region. Within the plasma membrane, most transmembrane proteins will be comprised of hydrophilic regions.
<h3>What is the
plasma membrane?</h3>
It is the laminar structure that delimits the cell composed of two layers of lipids, which orient their hydrophilic polar heads (that is, they have an affinity for water) towards the inside of the cell, keeping their hydrophobic parts and includes phospholipids, proteins and glycolipids that shape the unit.
Membrane phospholipids spontaneously assemble into a bilayer, whose hydrophilic regions are placed on the surface where transmembrane proteins are located since most of this type of protein is hydrophilic and hydrophobic regions are distributed in the central region.
Therefore, we can conclude that according to the research, the correct option is hydrophilic region. Within the plasma membrane, most transmembrane proteins will be comprised of hydrophilic regions.

Answer:
auditory ossicles
Explanation:
In reptiles, the eardrum is connected to the inner ear via a single bone, the columella, while the upper and lower jaws contain several bones not found in mammals. Over the course of the evolution of mammals, one bone from the lower and one from the upper jaw (the articular and quadrate bones) lost their purpose in the jaw joint and were put to new use in the middle ear, connecting to the existing stapes bone and forming a chain of three bones, the ossicles, which transmit sounds more efficiently
The mechanism that affected the gene pool of the immigrants that entered the United States through Ellis Island from 1892 to 1954 is B. gene flow. Gene flow is the transfer of genes or alleles from one population to another. The migration of millions of individuals from countries across the Atlantic Ocean to the United States is responsible for the changes in the gene pool of the immigrants.
