Abnormal cellular growth is caused by DNA mutations that divide in a much higher rate than normal
They train our immune system so it's ready when our bodies are attacked, and they aid in digestion and supply us with vitamins. ... Scientists and doctors can even utilize prokaryotes to help the human body.
False.
Pain receptors are free nerve endings- nociceptors- that are stimulated by the chemical released from damaged tissue.
These receptors alert us for possible danger but they don't display sensory adaptation. Sensory adaptation it's when the response to stimulus decreases even though the stimulus is the same, we just become unaware of it.
In pain sensations, that doesn't happen.
