What is an example of a cell that has specialized domains of plasma membrane?

Epithelial cell

Explanation:

A typical epithelial cell is characterized by the presence of special domains of the plasma membrane. An epithelial cell has an apical domain and a basolateral domain.

The apical domain of the epithelial cells is present towards the lumen of the organ while its basolateral domain covers the rest part of the cell.

The two domains differ from each other structurally and perform specific functions. Specialized appendages such as cilia are mostly present in the apical domain of the epithelial cells.

The specific distribution of proteins and lipids is maintained by tight junctions that do not allow the passage of substances between the two domains.

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.

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
