Which type of junction prevents transmembrane proteins in the apical part of the plasma membrane from diffusing into the basolateral part of the plasma membrane?

The correct answer will be- Tight junction

Explanation:

The cell membrane contains faces two sides: the faces the lumen of the cell is called the apical membrane while the side which faces the basal side and lateral side is known as a basolateral membrane.

The junctions are present in the layer of cells which allows the physical binding of the cell and also allows the communication between the cells.

Tight junctions are one of the types of junction which helps maintain the polarity of the cell by preventing the diffusion of the integral membrane proteins between the apical side to the basolateral side. This maintains the specialised function of the membrane-like endocytosis in apical membrane while exocytosis at the basal membrane.

Thus, Tight junction is the correct answer.

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
