What are 3 examples of signals that cells may receive? what is the most common type of signal?

3 examples would be touch, light and chemical.

and the most common signal would be chemical.

Hope this helps! (:

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.

i hope this
