The way bacteria and cancer cells find food is similar and involves one of life's oldest forms response to chemical signaling. A bacterium swims by using their flagella. If one were to place a spot of acid on one side of a Petri dish containing bacterial growth media and a spot of sugar on the opposite side with the bacteria in the middle, they swim towards the sugar responding by chemical signaling and creates the appearance of 'purpose' (which begs the question about the nature of purpose vs function).

This type of chemical signaling is called: A. positive reinforcement B. fermentation C. sexual orientation D. gravipercpetion E. chemotaxis or "movement induced by chemicals"
