All advertising

Evolutionary biology

Statistics

Anecdotal evidence

Pseudoscience

Correct! (See section 1·17 Pseudoscience and misleading anecdotal evidence can obscure the truth.)

Incorrect. (See section 1·17 Pseudoscience and misleading anecdotal evidence can obscure the truth.)

2. What is meant by the phrase “hierarchical organization of life”?

The “hierarchical organization of life” means that the chemical, cellular, and energetic aspects of life are most important.

The “hierarchical organization of life” refers to the fact that life is organized on many levels within individual organisms, including atoms, cells, tissues, and organs.

The “hierarchical organization of life” means that in the larger world, organisms themselves are organized into many levels: populations, communities, and the ecosystems within the biosphere.

The “hierarchical organization of life” means the same thing as “the scientific method.”

Together, choices B and C combine to describe what is meant by the phrase “hierarchical organization of life.”

Correct! (See section 1·19 Important unifying themes tie together the diverse topics in biology.)

Incorrect. (See section 1·19 Important unifying themes tie together the diverse topics in biology.)

3. From the graph shown here, the STRONGEST statement we can reasonably make is:

if we give textbooks to all the students who did not have textbooks, they all would score between 95% and 100% on the next exam.

there is a statistically significant negative correlation between having access to a textbook and scoring well on the exam.

there is a statistically significant positive correlation between having access to a textbook and scoring well on the exam.

having access to a textbook caused students to score better on the exam.

there is a positive correlation between having access to a textbook and scoring well on the exam.

Correct! (See section 1·16 Statistics can help us in making decisions.)

Incorrect. (See section 1·16 Statistics can help us in making decisions.)

4. Science as a way of seeking principles of order differs from art, religion, and philosophy in that:

all scientific knowledge is gained by experimentation.

science deals exclusively with known facts.

science denies the existence of the supernatural.

science limits its search to the natural world of the physical universe.

All of above ways can be used to help science.

Correct. (See section 1·18 There are limits to what science can do.)

Incorrect. (See section 1·18 There are limits to what science can do.)

5.

5. Statistics are used by scientists mainly to determine:

whether differences in results between control and treatment groups is theoretical.

whether a study needs to be repeated.

whether or not there was a bias in the study.

whether two numbers are the same or not.

whether differences in results between control and treatment groups is significant and important.

Correct! (See section 1·16 Statistics can help us in making decisions.)

Incorrect. (See section 1·16 Statistics can help us in making decisions.)
