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

identified molecule responsible for transporting information from the nucleus to the site
of protein synthesis? - Answers -mRNA

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. - Answers -The teacher provides stations around
the lab area with different types of laboratory equipment, followed by questions that can

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. - Answers -Allowing students to act out the roles played by
the key molecules during the energy-coupling reactions of the ETC.

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. - Answers -Facilitating a class discussion where
students share their knowledge through charts and illustrations summarizing the
excretory systems of different types of animals.

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. - Answers -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.

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. - Answers -
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.
The teacher should encourage them by saying that most students are willing to perform
the dissection, so they must do so as well or they will be marked down on the exercise.
The teacher should provide an alternative way for the students to perform the
dissection, such as with physical models or a web-based interactive simulation.
