3.0 Points |
Feedback: Great job. Question 16 of 33 How did Darwin define evolution? |
3.0 Points |
Feedback: Darwin described an evolutionary process that occurs when change happens in populations over generations. Read more in Chapter 11.
Question 17 of 33
A population of pocket mice has two coat colors: black and brown. There are more black mice on lava 3.0 Points rocks where there are hawk predators. This is an example of:
Feedback: Mice that are the same color as the rock (black) are able to survive predator attacks better because they are more camouflaged. This is an example of natural selection. Read more in Chapter 11.

3.0 Points |

3.0 Points |
Feedback: Great job. Question 22 of 33 Which of the following is accurate about mutation? |
3.0 Points |
Feedback: Although there are many processes that can change allele frequencies in a population, only mutation can result in new variation. Read more in Chapter 11.
Question 23 of 33
What are the four evolutionary forces that would disrupt population Hardy-Weinberg equilibrium? 3.0 Points
Feedback: Great job.
Question 24 of 33
A classic scientific study showed that crayfish on one side of the isthmus of Panama were more closely 3.0 Points related to other species on the other side of the isthmus than to each other. The most likely explanation for this result is:
Feedback: The most likely explanation is that a several separation crayfish species were separated by the formation of the isthmus and the then separated populations diverged. Read more in Chapter 11.
Part 3 of 5 - Part 2: Lecture Question 25 of 33 It is important to understand issues of the modern world but separating what in current literature? |
12.0 Points 3.0 Points |
Feedback: Knowing the different between quality research and false information is important to distinguish. See
Unifying Theme in Lesson Lecture

A plant physiologist notices a group of trees growing all in one direction, contrary to what she thinks 3.0 Points should happen. This is an example of what part of the scientific method?
Feedback: Great job.
Question 27 of 33
A molecular biologist notices something different in the genetic profile of an individual, performs careful 3.0 Points research, and thinks he discovers a new gene responsible for high blood pressure in humans. The last step is an example of what part of the scientific method?
Feedback: Great job.
Question 28 of 33
Biology is the study of life, as such it is focused on the things that are living or called what? 3.0 Points
Feedback: Great job!
Part 4 of 5 - Part 3: Lab 12.0 Points
Question 29 of 33
According to this week’s Lesson, which of the following topics did the Pew Research Center report 3.0 Points discrepancies in opinion between the general public and scientists?
