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 20seedlings 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?
The environmental temperature can affect the growth of a plant's root
Plants need light to grow
A colder environment produces longer roots
Plants need 60 days in order to grow their roots - CORRECT ANSWER-The environmental temperature can affect the growth
of a plant's root
A botanist would like measure the root length of various seedlings. Which tool would be best?
A ruler with precision to the half inch
A microscope and a ruler
A microscope with magnification to the 10th power
A microscope and a ruler with precision to the millimeter - CORRECT ANSWER-A microscope and a ruler with precision to the
millimeter
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 h as
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 t o
light 20 hours a day.
What problem has the researcher created in this experimental design?
The researcher does not have a control group.
The researcher has not kept the sample size equal across all groups.
The researcher has designed an experiment that does not test her hypothesis.
The researcher cannot replicate this experiment - CORRECT ANSWER-The researcher has not kept the sample size equal
across all groups
A student has been assigned an experiment into the life cycle of a frog. First, she needs to count the daily number of tadpol es
at her assigned pond. Which of the following would give her the most accurate and reliable data?
Going to the pond in every morning, collecting a 1 L sample of water, and counting the tadpoles
Going to the pond every morning at 10 a.m., collecting a 1 L sample of water, and counting the tadpoles
, Going to the pond every morning at 10 a.m., collecting a 1 L sample of water at 3 set locations at the pond, and counting the
tadpoles
Going to the pond once a week at 10 a.m., collecting a 1 L sample of water at 3 set locations at the pond, and counting the
tadpoles - CORRECT ANSWER-Going to the pond every morning at 10 a.m., collecting a 1 L sample of water at 3 set locations
at the pond, and counting the tadpoles
