A cell membrane, often referred to as a plasma membrane, is present in every cell and serves as a barrier between the interior of the cell and the outside world. The cell membrane is a lipid bilayer that is semipermeable. The cell membrane regulates the flow of substances into and out of the cell.
The cell membrane, commonly referred to as the plasma membrane, serves as the body of a cell. It also keeps the environment inside the cell constant, and that membrane has many functions. One is to introduce nutrients into the cell while removing toxic chemicals from it. Another is that the cell's plasma membrane, which is its outer membrane, will have proteins that interact with other cells. These proteins may be glycoproteins, which also contain a sugar moiety, or lipid proteins, which contain both a protein and a fatty acid. Proteins that stick outside of the plasma membrane also allow for cell-to-cell communication. The cell membrane also provides some structural support.

Answer: The person is heterozygous for the trait. The person is a carrier of the recessive allele of the trait.
Explanation: Take for instance the height trait. If H is a dominant allele for tall height and h is recessive allele for short height, a person who has one recessive allele and one dominant allele will have a genotype of Hh, this means that the person is heterozygous for the trait. In this example, the genotype Hh will manifest outwardly as tall height because H is dominant over h.
