Biology Midterm Review

Mr. Compton wants to know the effect of different types of fertilizer on the number of blooms on rose bushes.He believes that rose bushes will bloom more when given Type A fertilizer.He buys 40 rose bushes of the same species, which are all approximately the same age and height but have not bloomed.He gives ten roses Type A fertilizer, ten roses Type B fertilizer, ten roses Type C fertilizer, and ten roses no fertilizer. All of the rose bushes are planted in the same soil and given 300 mL of water once a day for 3 weeks.After the three weeks, Mr. Compton counts the number of blooms on each rose and averages them together.

Which of the following is the independent variable in the experiment?

• Type of fertilizer

• Amount of water

• Type of rose

• Soil
