3. Including the final exam, this course has ______ exams.: 4
4. True or False? An individual passes all lab assignments with scores over 90%,
but after calculating their grade for all lecture assignments (exams, quizzes,
clicker points, etc.) finds that they have a 58% in the lecture alone.
This individual will pass BIOL 117.: False
5. Quizzes are due...: Monday nights
6. A student with that passes both lecture and lab and gets an overall grade of
89.44% in this class will receive what letter grade?: B
7. Natural selection creates new traits / alleles: False
8. What term is used to describe all the alleles at every locus for all individuals
within a population?: gene pool
9. Evolution is a change in the [x] of a [y] over time: Evolution is a change in the
gene pool of a population over time
10. Small populations are especially susceptible to _______: genetic drift
,11. What variable in the Hardy-Weinberg equation describes the proportion of
heterozygotes?: 2pq
12. A few individuals move between populations. This is an example of: gene flow

and release it more readily to your tissues
27. The countercurrent exchange in fish gills ensures that ______: The partial
pressure of oxygen is always greater in the surrounding water than in the adjacent
fish gill
oxygen always moves from the water into the fish's tissues as it passes over the gills
28. The lymphatic system derives its fluid from the______: capillaries
29. Which chamber of the human heart is surrounded by the most muscle?: left
