Answer:
target cell
Explanation:
Cell communication includes one or more signaling cells and the target cell. Signaling cells produce signals. In the case of chemical signaling, the signaling cells produce chemical signals such as hormones or neurotransmitters or ligands. Target cells are the cells that respond to a specific signal produced by the signaling cell.
To receive and respond towards the signal, the target cells produce receptors where the signaling molecules bind to produce the desired effects in the target cells. For instance, liver and muscle cells are one of the primary target cells for the pancreatic hormone insulin.
The properties of gamma which paved its way to the area of medicine are having high energy of all the waves in the spectrum. With this they can penetrate into almost all surfaces. One application would be its use in killing cancer cells and to examine the internals of the body.
