QUESTION 20 Most copepods have an r selected life history, characterized by ______ predation of adults and a(n) ______ mating strategy high, semelparous high, iteroparous low, semelparous low, iteroparous QUESTION 21 David Lack hypothesized that the clutch sizes which yield the most surviving young would be the most common. Field data regularly shows that bird clutch sizes are usually smaller than Lack's hypothesis. Which of the following is not a reason for this discrepancy? By investing fewer resources into her current clutch, the mother will be better able to reproduce the next season. Having fewer offspring allows the mother to invest more into each of them. Some eggs are eaten by predators. Individual birds differ in their reproductive capacity.

Step 1
This is because r-selected species, like copepods, are characterized by high reproductive rates and a single, often fatal, reproduction event (semelparity). Show more…

When Lake Mendota was completely covered with algae, biologists used the concept of trophic cascades to solve the problem by introducing predatory fish. When they did this, the predatory fish caused a decrease in plankton feeding fish, which resulted in an increase in herbivorous plankton with consequent decrease in algae.

Based on the patterns observed, what potential reasons would explain why the population would be out of HWE? Please select all that apply: - Directional selection - Stabilizing selection - Disruptive selection Hartnup disease is an autosomal-recessive disorder of intestinal and renal transport of amino acids. The frequency of affected newborns is about one in every 14,000. Assuming random mating, a heterozygote would be born around once every.

2. You are a conservation biologist working on brown-striped snipes. Snipes are rare aquatic insects, and populations tend to be isolated from one another, because individuals migrate only infrequently from the pools where they hatch. As a result there is little gene flow, and populations tend to be small in size. a. How is genetic variation likely to be partitioned within vs. between populations? (3 pts) b. Is drift likely to play an important role in altering population allele frequencies? (3 pts) c. If migration increased among populations how would this affect genetic variation within populations and between populations? (3 pts) d. Due to a rare but large migration event, the size of one population increases 4-fold. Will the potential for genetic drift increase, decrease or remain unchanged in the population? (3 pts)
