Question 2

A model is a formal description of a scientific hypothesis. Which of the following types of models provides the most precise description of a hypothesis?

Answer 2

Mathematical

Question 3

An experiment enables one to demonstrate that a correlation between two variables results from cause and effect.

Answer 3

True

Question 4

A well designed experiment ___________.

Answer 4

controls for environmental and genetic factors, involves the replication of experimental subjects, randomizes experimental subjects among treatments.

Question 5

Unlike Wallace, Darwin did not believe that natural selection required variation among individuals.

Answer 5

False

Question 6

Wallace used induction to develop a model of evolution by natural selection.

Answer 6

True

Question 7

Unlike Wallace, Darwin’s conceived his theory of evolution without observing species living on islands.

Answer 7

False

Question 8

Both Darwin and Wallace must have assumed that differences among individuals were passed onto their offspring.

Answer 8

True

Question 9

Similar to Wallace, Darwin conceived a theory of evolution by natural selection while voyaging around the world.

Answer 9

False

Question 10

Both Wallace and Darwin adopted a worldview described as either naturalistic evolution or theistic evolution.

Answer 10

True

Question 11

The ability to digest milk likely varies genetically between African populations.

Answer 11

True

Question 12

The ability to digest milk likely conferred a reproductive advantage in populations that relied on cows for nutrition.

Answer 12

True

Question 13

Natural selection likely generated the variation in lactose tolerance among populations of Africans.

Answer 13

True

Question 14

If biologists sampled a population of Asians who never relied on cows for nutrition, the majority of them likely digest lactose without difficulty.

Answer 14

False

Question 15

Lactose tolerance likely depends on genetic variation that one could artificially select.

Answer 15

True

Question 16

Both height and eye color in this family follow a pattern consistent with blending inheritance.

Answer 16

False

Question 17

According to a model of blending inheritance, the children should be as tall as their father.

Answer 17

False

Question 18

According to a Lamarckian model of inheritance, a child would have opaque or cloudy eyes if its mother developed a cataract prior to pregnancy.

Answer 18

True

Question 19

Human height is likely controlled by one gene with two alleles.

Answer 19

False

Question 20

The eye color of the children was likely determined by blending inheritance.

Answer 20

False
