Questions and Answers
During the early 1900s, scientists performed an experiment which identified the existence of a
substance other than DNA was involved in protein synthesis. Since they knew DNA could not be found
outside the nucleus, their experimentation identified the site of protein synthesis in the cytoplasm.
Which of the following was the newly identified molecule responsible for transporting information
from the nucleus to the site of protein synthesis?
mRNA
The diagram below shows a static depiction of cellular activity occurring across a cellular membrane.
Which of the Following pair of processes does this diagram most directly model
Homeostasis and transport of molecules.
Cells can generate as many as 36 to 38 molecules of adenosine triphosphate (ATP) from the
metabolism of one molecule of glucose. Which cellular process results in this amount of ATP
production?
Aerobic cellular respiration
Which of the following is an aspect of inquiry-based science instruction?
a)A teacher-facilitated discussion after a lab investigation.
b)A student forming a hypothesis prior to a lab activity.
c)A student writing a formal research report.
d)A video presentation of science principles to be included in a unit of study.
A video presentation of science principles to be included in a unit of study.
Which of the following practices describes the best summative assessment for determining whether
students understand the correct use of laboratory equipment?
a)The teacher provides stations around the lab area with different types of laboratory equipment,
followed by questions that can only be correctly answered if students correctly use the equipment at
the station.
b)The teacher provides the class with a description of a hypothetical laboratory exercise, asking each
student to list the pieces of equipment they would use to perform the exercise.
c)The teacher gives a multiple-choice test about laboratory techniques in which students must match
function with the laboratory equipment.
d)The teacher has students write individual lab reports that include hypothesis, materials and
methods, results, and discussion sections for each laboratory exercise they perform throughout the
semester.

Which of the following activities is most likely to engage and inform all students, including English-
language learners, about the energy-coupling reactions of the electron transport chain, ETC, in certain
organelles?
a)Assigning students into small groups to write a short paper describing the major energy-coupling
reactions of the ETC.
b)Allowing students to watch a cartoon that demonstrates the roles of each molecule in the ETC and
the movements of protons and electrons by the molecules.
c)Allowing students to act out the roles played by the key molecules during the energy-coupling
reactions of the ETC.
d)Inviting a college biology professor to give the class a lecture, including slide illustrations, about the
ETC.
Allowing students to act out the roles played by the key molecules during the energy-coupling
reactions of the ETC.
Which of the following is the best way to assess student's prior knowledge about the various
mechanisms involved in how animals process and excrete wastes?
Facilitating a class discussion where students share their knowledge through charts and illustrations
summarizing the excretory systems of different types of animals.
Assigning reading from a textbook chapter on mechanisms of excretion as the evaluation questions at
the end of the chapter.
Having students individually complete a worksheet in which they match animals with the types of
nitrogenous waste the animals excrete.
Asking each student to select an animal and then write a short paper describing the excretory system
of the animal.
Facilitating a class discussion where students share their knowledge through charts and illustrations
summarizing the excretory systems of different types of animals.
Which of the following is a type of summative assessment?
A test review game
A practice problem during a group assignment
An end of course exam
An warm-up question
An end of course exam

A teacher wishes to introduce the topic of climate change to a class. The teacher knows this is a
controversial topic as some of the students in the class do not believe that climate change is occurring
or that human activity contributes to the phenomenon. Which of the following actions describes a
method for students to evaluate the scientific evidence relating to climate change?
Facilitate a discussion asking students to outline their prior knowledge about climate change and the
contributing factors.
Allow students to watch a fictional disaster movie in which the plot revolves around the negative
effects of climate change, then facilitate a discussion about how climate change caused the disasters
in the movie.
Lead a lecture on the effects of climate change, the human activities that scientists claim are
contributing factors and the ways by which people can modify their behavior to try to slow climate
change.
Assign students into groups that will research climate change from reliable sources that both support
and refute the evidence, then divide the class into teams to debate the evidence on both sides of the
argument.
A teacher wishes to assign a research project about organelles in eukaryotic cell in a class. Which of
the following action should the teacher do to clarify project evaluation criteria?
Provide the students with numerical grades that represent excellent, good, or poor projects.
Provide the students with a detailed rubric for the project.
Provide the students a list of reliable websites that have examples of similar projects.
Provide the students with clearly written, detailed directions for the project.
Provide the students with a detailed rubric for the project.
A biology laboratory exercise requires that pairs of students dissect frogs and that each student
independently complete a worksheet relating observations made during the dissection to basic
knowledge of anatomy and physiology. A couple of students in the class are reluctant to view or
perform the dissection. Which of the following is the best way for the teacher to respond to the
reluctant students?
The teacher should excuse them from the exercise but tell them to complete the worksheet, using
their textbook as a reference.
