Explanation:
Radioactive dating works on the principle that a radioactive isotope can decay into the stable daughter nuclei at a constant rate. Geologist generally use the principle for half life. Half life is the time required for half of the radioactive substance to decay. This is constant for a particular element.

Answer:
The environments in which cells grow often change rapidly. For example, cells may consume all of a particular food source and must utilize others. To survive in a changing world, cells evolved mechanisms for adjusting their biochemistry in response to signals indicating environmental change. The adjustments can take many forms, including changes in the activities of preexisting enzyme molecules, changes in the rates of synthesis of new enzyme molecules, and changes in membrane-transport processes.
Initially, the detection of environmental signals occurred inside cells. Chemicals that could pass into cells, either by diffusion through the cell membrane or by the action of transport proteins, and could bind directly to proteins inside the cell and modulate their activities.
