Given the Darrow-Yannet Diagram below, which answer would correctly describe what occurs between the ICF and ECF when a HYPOtonic distilled-water solution is administered to a patient intravenously? (HINT: Remember that osmolarity/concentration is on the Y-axis and volume is on the x-axis in these diagrams)

When rodent populations become large and dense, a lot of fighting occurs.  (A) Some people have claimed that this is because in dense populations, individuals encounter many non-relatives.  Aggression is favored in these encounters with “strangers” as opposed to encountering kin and offspring in which cooperative behavior would be favored.  (B) Others have criticized this argument on the grounds that aggression in dense populations stems from the fact that individuals lack familiarity with those animals that they meet, not from any supposed reproductive advantage of being aggressive to non-relatives.  Define each of these explanations as either ultimate or proximate (make sure to explain your choice).  Is one explanation more correct than the other one?  In other words, should the two groups be arguing with each other?  Why or why not?

The best solution to the iterated prisoner’s dilemma problem proposed by Robert Axelrod was:

(A) Given the figure below, is predator confusion or prey dilution effect being measured for percent of ping pong balls captures as singles, pairs, in trios or as quadruplets?  Explain your reasoning for your choice. (2 pts) (B) Does the relationship shown in the figure indicate that a predator confusion or prey dilution effect is actually occurring?  Explain your answer.  (2 pts)

What is the probability that you and your maternal great-grandfather (through maternal grandmother) share the same allele by common descent?  In other words, what is the rb between you and maternal great-grandfather?

Identify a factor of the following polynomial 6×2+7x-3

The chart below shows the percent change in mass of eggs in various salt solutions over a 1 hr period. By looking at the trajectory of the lines, you can tell if there was more or less salt in the egg in comparison to the solution based on whether water move out (it decreased in mass), or if water moved in (it gained mass). Based on the diagram, does the egg have more or less salt than 30%, given that the egg in the 30% solution decreased in mass?

In the redback spider, the male inserts his copulatory organs, then does a back flip that places its body next to the female’s mouthparts.  She may then feed on the male during mating.  What evidence below would support the hypothesis that a male’s sexual suicide was maladaptive?

In the image below, the top portion shows the onions cells under normal conditions, the bottom portion of the image shows the cells when placed into a high 15% salt solution. Is the solution hyper, hypo, or isotonic to the onion cells?

Correctly correlate the condition name with its pH conditions.
