21. Geranium plants were grown in normal light. Half of the leaves on each plant were covered with aluminum foil to prevent light from reaching them. Leaves that were kept in total darkness were tested for the presence of starch. Leaves receiving normal ambient light were also tested for the presence of starch. Which of the following are variables that should be standardized (kept the same in both the experimental group and control group) for this experiment?
a. amount of water
b. species of geranium plant
c. type of soil
d. temperature
e. all of these
22. A farmer wanted to know if ABC fertilizer would be good for his crop plants. He fertilized his 1,000 tomato plants with ABC. For a control group, he did not put any fertilizer on his 1,000 green bean plants. His tomato plants did not grow well at all, but he got a great crop of green beans. He concluded that ABC fertilizer was a waste of money.
