Answer:
Option (2) and (3).
Explanation:
Cancer is the uncontrolled division of the cell that might results in the loss of apoptosis in the cells. The cancer cell shows the property like angiogenesis and loss of contact inhibition.
Both the hereditary factors like mutations in some gene and environmental factors like any mutagen may inhibit the process of the cell division. Both these factors mainly inhibits the gene that are responsible for the regulation of the cell cycle like p53, Rb.
Thus, the correct answer is option (2) and (3).

Answer:
Biological
Explanation:
The biological species concept differentiates one species from the others on the basis of reproductive isolation. It assumes that the two organisms that belong to different species can not interbreed to produce a viable and fertile progeny. On the other hand, the members of the same species can reproduce with each other to produce progeny. In the given example, the populations of damselflies are observed for their reproductive behavior. Since the flies of all the populations are able to breed with each other, they belong to the same biological species.
