The venus flytrap is a carnivorous plant that lives in swampy habitats where there is little
nitrogen. As a result, the flytrap has evolved to receive nitrogen and other nutrients from insects.
The plant has two leaves that resemble jaws, and when the insects land on the plant, the leaves
close on the insect. The plant then digests it.
A researcher grows three venus flytraps in a greenhouse containing swampy soil. Plants 1 and 2
are given equal amounts of fertilizers X and Y. Plant 3 is not given any fertilizer. Fertilizers X
and Y differ in the amount of nitrogen they contain.
17. What is the control group for this experiment?
a. Plant 1
c. Plant 3
b. Plant 2
d. Plants 1 and 2
18. What is the dependent variable?
a. Fertilizer
b. Venus flytrap
c. Amount of Nitrogen
d. Plant Growth
19. What is the independent variable?
a. Fertilizer
b. Venus flytrap
c. Amount of Nitrogen
d. Plant Growth
The two graduated cylinders pictured can hold the same amount of water and use the same scale.
A student measures the masses of metal balls. One ball is made of aluminum and the other ball
is made of lead. The student adds 50 mL of water to each graduated cylinder and then drops one
metal ball into each graduated cylinder.
20. Which tool did the student use to measure the mass of each metal ball?
a. Ruler
c. Balance
b. Timer
d. Graduated Cylinder
