Living things differ from nonliving things in that they:

can grow, reproduce, and respond to their environment

are always visible to the naked eye

do not require energy to survive

are made only of non-organic materials

Crosscutting concepts help unite the study of biology by:

providing a framework to connect different areas of biology

limiting the study to cellular biology

ignoring patterns and relationships in nature

Biology can be studied at different scales, or levels, such as:

molecules, cells, organisms, populations, and ecosystems

only ecosystems and populations

Scientists use a common system of measurement because it allows them to communicate results clearly and consistently.

Because it allows them to communicate results clearly and consistently.

Because it is easier to use than other systems.

Because it is required by law in all countries.

Because it is the oldest system of measurement.

it means that a new idea will only be accepted if it is backed by evidence

it prevents scientists from accepting new ideas

it encourages scientists to readily accept new ideas

Which of these best describes why scientists and engineers would make different models of the same object?

scientists and engineers sometimes need to look at the same thing in different ways

scientists and engineers do not share their models with other researchers

scientists and engineers never use the same model that is used by other researchers

scientists and engineers need to make a new model to test work from other researchers

Why do scientists all over the world use the metric system?

so that scientists can understand data from other scientists

meter sticks are found in labs and science classrooms

the metric system is a secret system used only by scientists

the units are easy to translate into any language

A scientist wants to determine whether something is living or nonliving. Which of the following is a characteristic that a scientist could use to tell that something is living?

the object is made up of two or more cells

the object can hear, smell, and taste its environment

Valerie designed and conducted an experiment on pothos plants, which are common houseplants. Her hypothesis is that the direction of light will affect the growth pattern of a pothos plant. To test the hypothesis, she sets up two test groups of pothos plants and observes them three weeks later. The table summarizes the test groups and observations. What are the roles of the two test groups in this investigation?

One is the experimental group and one is the control group, and together they show the effect of the direction of light

Both are experimental groups, and each individually shows the effect of the direction of light.

Both are control groups, but only Test Group 1 shows the effect of the direction of light.

Both are experimental groups, but only Test Group 1 shows the effect of the direction of light.

After analyzing the results of the experiment, Valerie asks if her hypothesis should be classified as a theory. Which is the best response to Valerie’s question?

No, because a theory is a highly reliable explanation that incorporates many well-tested hypotheses

Yes, because her data support the hypothesis

Yes, but only if additional experiments show similar results

No, because the experiment did not provide enough data to support the hypothesis

Evolutionary theory has become the central organizing principle of biological science. Could this scientific theory ever become a scientific law?

No, because a theory is a complex explanation that does not become a law

Yes, if scientists decide that enough evidence supports the theory

Yes, if the theory is shown to predict future events

No, because a theory can be proven correct while a law cannot be proven

A griffin is a mythical creature that appears in many stories. It has the head of an eagle and the body of a lion. What role, if any, could the griffin have in the science of biology?

The griffin has no role in biology, because it is not real

The griffin could be the subject of an investigation of animals

The griffin could be cited as evidence to evaluate a hypothesis or theory

The griffin could be used to test new ideas about animal structures or behaviors

After a team of scientists completes an investigation, they submit an article about the investigation to a scientific journal. Before the journal publishes the article, they send it to other scientists for an anonymous, independent review. What is the purpose of this review?

to evaluate the methods and test the results of the investigation

to guarantee that the conclusions of the investigation are correct

to make sure the investigation has practical, economic benefits

to improve the appeal of the article to the general public

When news of a scientific discovery is reported, readers must assess the credibility of the claim. For scientific discoveries in general, which statement indicates a valid and credible claim?

The scientist followed strict standards of investigation and scientific methodology throughout the research

The scientist aimed for precision and accuracy by using a small sample size

The scientist assured that the experiment was broad in scope by testing many variables in each trial

No other scientists replicated the experiment to avoid the legal issues of patent infringement

In 1999, teams in Colorado and California were working together to put NASA’s Mars Climate Orbiter in orbit around Mars. The mission of the orbiter was to look for evidence of water. One team used English units of measurement. The other team used metric measurement. As a result, the spacecraft was lost. What would be the simplest and most cost-effective way to avoid mistakes like this in the future?

All personnel and missions should use the metric system

Missions should be run by only one facility

Another office should oversee every aspect of missions

NASA should coordinate all missions with the European Space Agency

Which of the following scientific reports is MOST likely to be affected by the bias of the scientist?

A scientist who developed a new strain of cotton reports on the benefits of cotton

A scientist who studies viruses reports ways to prevent viral infections

A scientist who studies wildlife in Australia reports on the native species of Australia

A physician who works for a hospital reports on the effectiveness of a new medicine

Which statement BEST explains why viruses are typically classified as nonliving?

Viruses fail to satisfy many of the properties of living things, including obtaining and using energy, and responding to the environment

Viruses satisfy all of the properties of living things, but are too small to be alive

Viruses satisfy all of the properties of nonliving things, such as not moving and not using energy

Viruses fail to satisfy each of the properties of living things, including the use of DNA and universal genetic code

Which of the following is an example of a scientific investigation?

Testing how different amounts of sunlight affect plant growth

Writing a poem about the beauty of the stars

Debating the meaning of life in a philosophy class

Creating a painting of a forest

What is the main purpose of using a control group in a scientific experiment?

To compare results and determine the effect of the variable being tested

To ensure all data is qualitative

To guarantee the experiment will succeed

To make the experiment more complicated

Why is it important for scientific results to be repeatable by other scientists?

It helps confirm the reliability and accuracy of the findings

It allows scientists to keep their methods secret

It makes the experiment more expensive

It ensures only one person can perform the experiment

a logical interpretation based on prior knowledge and experience

a group in an experiment that is exposed to the same conditions as the experimental group except for one independent variable

experiment in which only one variable is changed

factor in a controlled experiment that is deliberately changed

variable that is observed and that changes in response to the independent variable

a combination of chemical reactions through which an organism builds up or breaks down materials

signal to which an organism responds

well tested explanation that unifies a broad range of observations and hypothesis, enabling scientists to make accurate predictions about new situations

relatively constant internal physical and chemical conditions that organisms maintain

particular preference or point of view that is personal rather scientific
