c) Gives a cell its distinctive characteristics

Explanation:

Carbohydrates perform two main functions in the cell's membrane: <em>they participate in cell recognition and adhesion</em> (cell-cell signaling or cell-pathogen interactions), they also have a structural role as a physical barrier.

Most of the carbohydrates linked to the membrane are in the form of <em>glycoproteins oy glycolipids</em>, these are the molecules that share information and recognize host cells. <em>Glycocalyx </em>is another way we find carbohydrates in the cell membrane, this layer has cell-adhesion molecules that enable cells to adhere to each other.

Which phase of mitosis is the last phase that chromatids are together
Vladimir [108]

Answer:

Metaphase

Explanation:

The M phase of the cell cycle is the phase during which the nuclear content and cellular content is distributed. The distribution of the nuclear content takes place in four phases: prophase, metaphase, anaphase and telophase.

The homologous chromosomes are aligned at the equatorial plate during the metaphase after which the chromosomes separate. The phase during which the separation of the chromosomes takes place is known as anaphase so the phase before the anaphase is the phase during which the chromatids are not separated that is the metaphase.

Thus, metaphase is the correct answer.
