Multiple Choice Questions:
1. You have formulated a hypothesis that water is necessary for seed germination.
To test your hypothesis, one set of lettuce seeds is placed in water with warm
temperatures and adequate lighting. Another set of identical seeds is placed in
the dry under the same set of conditions. The control in the experiment is
(a) seeds in the dry
(b) seeds in the light
(c) warm temperature

2. A group of medical researchers recently tested the effects of a cholesterol-
lowering medication, Drug A on men who had high blood levels of cholesterol. The
researchers did the following experiment and obtained the indicated results. One group of
150 men took a tablet containing 40 mg of Drug A for 90 days; 120 of this group
decreased their blood levels of cholesterol by at least 10 %. Another group of 150 men
was given a tablet with no added Drug A for 90 days; 25 of these men decreased their
blood levels of cholesterol by at least 10%.
Which of the following is the most reasonable and accurate conclusion based on
results obtained in this experiment?
(a) Drug A is good for men
(b) Drug A is found in the blood of men
(c) men taking tablets supplemented with Drug A will show a decrease in
cholesterol levels in the blood
(d) men taking tablets supplemented with Drug A will show an increase in
cholesterol levels in the blood
(e) blood levels of cholesterol are not affected by oral supplementation of Drug A
4. Which statement best describes the relationship between plants and animals on earth?

, (c) Plants produce O2 and sugars and animals produce CO2 and H2O
(d) Animals produce O2 and sugars and plants produce CO2 and H2O
5. Think of the cell as a factory, in which the organelles are specialized sites of production.
All cells have a power plant, the mitochondrion. Plant cells have an additional “reactor”
for the production of usable energy. It is called the _____.
(a) golgi body

(c) central vacuole
(d) vesicle
(e) chloroplast
6. A researcher planted seeds from four types of wheat (Types A, B, C, and D) in a
greenhouse to determine which type of wheat grew fastest. The plants were grown for 10
days and measured. The results are shown below. Choose the data set that demonstrates
that Type C wheat grew the fastest.
1 (a) A = 20 cm, B = 11 cm, C= 5 cm, D= 2 cm.
2 (b) A = 2 cm, B = 5 cm, C= 1 cm, D= 2 cm.
3 (c) A = 22 cm, B = 11 cm, C= 25 cm, D= 4 cm.
4 (d) A = 30 cm, B = 12 cm, C= 28 cm, D= 1 cm.
5 (e) A = 21 cm, B = 12 cm, C= 20 cm, D= 15 cm.
Use the following information to answer questions 7 & 8 below. A group of medical
researchers recently investigated the effects of Drug X on lowering blood pressure in a group of
hypertensive middle-aged women. The researchers did the following experiment and obtained
the indicated results: One group of 150 women took a tablet containing Drug X for 3 weeks – 95
of these women decreased their blood pressure by at least 10% (three women from this group
dropped out of the study). Another group of 150 women was given a tablet with no added Drug
X for 3 weeks – 10 of these women decreased their blood pressure by at least 10% (two women
from this group dropped out of the study).
7. Which of the following was the control group in this experiment?
a. the group of participants that received tablets containing Drug X.
b. the group of participants that received tablets that did not contain Drug X
c. the number of participants in each group at the beginning of the experiment
d. the number of participants in each group at the end of the experiment
e. the amount of Drug X contained in the tablet
8. Which of the following is the most reasonable and accurate conclusion based on the
results obtained in this experiment?
