1. Students planted 100 seeds in two different plots of land on the same day. Both plots of land measured 10 square meters. They recorded data for one year.

3. Based on the data in the table, the taller height of the population of plant number two is most likely the result of which of the following factors?

• Success rate of the sprouts

• The average local rainfall

• pH of soil in the area

• Genetic factors of the plants

Students treated a population of bean plants with fertilizer. They observed that these plants, on average, were taller than another population of the same kind of bean plants that were not treated with fertilizer. These observations lend support to which of the following conclusions?

• Not all plants respond to fertilizer the same way.

• Fertilizer can affect the growth of bean plants.

• Survival of bean plants is dependent on fertilizer.

• Only fertilizer can make bean plants larger.

Students planted several radish plants (Raphanus sativus) in their school garden. Students were allowed to take some of the plants home. One student observed that the plants grown at home were taller and had more leaves. She proposed the idea that genetic differences were responsible for the differences between the plants grown at school and the plants grown at home. Which of the following is the best argument against this idea?

• Genetic factors cannot influence plant height or leaf growth.

• Environmental factors are usually stronger than genetic factors.

• The genetic material of all the plants would be the same.

• Changing environments can alter a plant's genetic material.

Which of the following procedures would provide the best data to test the effect of daylight hours on the number of blooms on rose bushes?

• Count the number of blooms on rose bushes in different areas of the world that have different amounts of daylight.

• Research the kinds of rose bushes that have the highest number of blooms to see how much daylight they need.

• Collect data on the number of blooms on rose bushes all grown under identical conditions, except hours of daylight.

• Study a single rose bush during different seasons and under different amounts of daylight to see when it has the most blooms.
