Which would be the most appropriate way to determine the color of the leaves quantitatively?

• Survey 100 people and ask what color they observe after two days.

• Repeat the experiment ten times and take the average of the data.

• Use an instrument to find the percent of red, green and blue in the leaves.

• Use a ruler to measure the height of the leaves in centimeters or inches.

A biologist is testing a new treatment on corn plants infected with a disease. It is important to have a control group to show that–

• The application of the treatment is easy and cost-effective.

• The treatment is safe for animals in the environment.

• The results of the experiment can be duplicated with other plants.

• Results are caused by the treatment and do not happen naturally.

Students place one seed-producing plant on a screened-in patio and another of the same species on an open patio. The students observed that the plant on the open patio produced seeds, while the other on the screened-in patio did not. The students may conclude that–

• The plant on the open patio was pollinated by insects.

• The plant on the screened-in patio received less carbon dioxide.

• The plant on the open patio received more moisture from the morning dew.

• The plant on the screened-in porch produced spores instead of seeds.
