Answer:
Cell division
Replication
Explanation:
Traditional chemotherapy drugs target cell metabolic processes which enabled it to thrive under certain conditions and then halts such processes such as cell division or results in cell death.
Thus, these drugs are cell poisons, causing multiple side effects. Some of the other cell processes that these cells target also include replication and motility.
Answer:
This structure has not been highly beneficial for the organism
Explanation:
Vestigial structures are cells, tissues, and/or organs that have no apparent function. Vestigial structures are retained during the course of the evolution, but often they are degenerate and/or atrophied (due to disuse). In general, these structures are homologous to anatomical structures that play a specific role in evolutionarily related species. Some examples of vestigial structures include, among others, the presence of the appendix in humans and wings in flightless birds.
