Answer:

Cells that respond to peptide hormones usually do so through a sequence of biochemical reactions involving receptor and kinase activation. In order for cells to respond, it is necessary for first and second messengers to communicate. This is possible because <u>C) G protein acts as the link between first and second messengers </u>.

Explanation:

When the first messengers join the receptor, in the external membrane of the cell, it produces a change in the shape of the receptor that causes the join of the G protein to this structure. The G protein joined to the receptor and the first messenger modulates the activity of the second messengers inside the cell.

Cancer cells are anaplastic in that they "form backward" to an earlier de-differentiated state. the cells have nuclei that vary
soldier1979 [14.2K]

The cells have nuclei that vary in size and shape, termed pleomorphism.

Pleomorphism is usually defined in biology as the occurrence of multiple structural forms during the life cycle of an organism. In anaplasia, it represents multiple structural forms of nuclei. Pleomorphism is a characteristic feature found in malignant neoplasms, and dysplasia, but it can also be found in certain benign cell types.

Compare and contrast polysaccharides and nucleic acids in terms of monomer diversity and how they monomers are joined together
harkovskaia [24]

The monomer units of the carbohydrates vary in their total numbers extensively. Moreover, positions of the carbonyl groups along with the orientation of the hydroxyl groups also vary in the carbohydrates' monomers. The presence of any modification is also variable.

On the other hand, the nucleic acids have only 4 monomeric units. The linkages between the nucleic acid residues have less geometry than the glycosidic linkages.
