Aresearcher is trying to produce a new cancer drug to be tested on small tumors. the tumor has to be localized in a small area of the body and cannot have metastasized (spread to other areas of the body). furthermore, this drug must prohibit the signaling from one tumor cell to another tumor cell. given the above information, this new drug will prohibit

The options are

A. autocrine signaling between tumor cells.

B. endocrine signalizing between tumor cells.

C. direct physical contact between tumor cells.

D. paracrine signaling between tumor cells.

The RIGHT ANSWER IS D.

D. paracrine signaling between tumor cells.

Explanation:

Paracrine signaling is a type of cell-cell communication through which a cell gives a signal to cause changes in neighbouring cells, changing the behavior or differentiation of it's neighbouring cells.

Since, the tumor has to be localized in a small area of the body and cannot have metastasized (spread to other areas of the body). The new cancer drug would have to inhibit paracrine signaling between tumor cells.

one would be wind another would be water density
