A Biology class wants to investigate what concentration of a salt solution is most
effective in preventing the growth of bacteria. Students prepare five dishes of
agar (a gelatin-like substance used to cultivate living material). They spread
solutions of different salt solutions on four dishes, leaving one dish untouched.
They then introduce bacteria on all the dishes and observe the dishes for the
