• Organs, cells
• Cells, tissues (Answer)
A botanist hasrecorded careful data examining the relationship
between temperature and root growth. As you consider her
graph, how might you suggest she improve the experiment?
Correct Answer • Use a different species of plant that is better
suited for cold temperatures.
• Increase the range of temperatures • Increase the sample size of
seeds for each temperature (Answer)
• Study the root growth at higher temperatures
A botanist wants to determine if environmental temperature
affects root growth. In her
experiment, she creates 4 rooms at temperatures that vary by 5
degrees F. Each room gets 20
seedlings of the same species, which she grows on agar plates
for 60 days.
Once a day, she measures the length of each seedling's root. At
the end of 60 days, she
compares the length of the roots with the room temperature. She
finds the the room with the
lowest temperature produced the longest roots.
,Which of the following is best identified as a hypothesis?
Correct Answer •The environmental temperature can affect the
growth of a plant's root. (Answer)
•Plants need light to grow.
•A colder environment produces longer roots.
•Plants need 60 days in order to grow their roots.

A particular atom is uncharged, and it has an electron
configuration of 1s2 2s2 2p⁶ 3s2 and a mass number of 14. How
many protons does it have? Correct Answer • 14
, •6
•8
• 12 (Answer)
A researcher is conducting an experiment on root growth and
light exposure. The researcher suspects that, since plants go
underground, roots will grow better if they have less exposure to
light. The researcher divides seeds into 4 groups. Group 1 has 20
seeds and is planted in dirt. Group 2 has 20 seeds and is placed
in an agar dish exposed to light 2 hours a day. Group 3 has 5
seeds and is placed in an agar dish exposed to light 4 hours a
day. Group 4 has 5 seeds is placed in an agar dish exposed to
light 20 hours a day.
What problem has the researcher created in this experimental
design? Correct Answer • The researcher does not have a
control group.
• The researcher has not kept the sample size equal across all
groups. (Answer)
• The researcher has designed an experiment that does not test
her hypothesis.
• The researcher cannot replicate this experiment
A researcher wants to examine the effectiveness of a new
medication for blood pressure. The medication is taken daily
with recommended dosage of 10 mg. The researcher recruits 100
adults for a study. Sixty of these adults will take the new
medication, and 40 of the adults will serve as a control group.
All adults will participate in the study for 6 months.
