Based on the data shown in the graph, select the statements that describe what happens whenever one sex becomes rare or common. When one sex becomes rare, parents producing that sex have higher fitness due to a higher probability of mating success in their offspring. The rare sex becomes more common. When one sex becomes common, parents producing that sex have reduced fitness due to a lower probability of mating success in their offspring. The common sex becomes rarer. When one sex becomes rare, the other sex becomes common due to random fluctuations in the production of male and female offspring. The fitness of the parents is not affected. When one sex becomes either more rare or more common, parents produce an equal number of sons and daughters. The sex ratio returns to an equal number of males and females.

Which row below best describes why the population of adult mosquitoes would drop so dramatically during this time period Feb. 5, 2007 Something is wiping out honey bees across North America and a team of researchers is rushing to find out what it is. What’s being called Colony Collapse Disorder (CCD) has now been seen in Pennsylvania, North Carolina, Florida, Georgia and way out in California. Some bee keepers have lost up to 80 percent of their colonies to the mysterious disorder. Whatever kills the bees targets adult workers, which die outside the colony — with few adults left inside, either alive or dead. The disorder decimates the worker bee population in a matter of weeks. Aside from making honey, honey bees are essential for the pollination of tens of million of dollars worth of cash crops all over the United States. That’s why almond growers of California, for instance, are taking notice and pledging funds to help identify and fight the honey bee disorder. Among the…

Two human populations have the same net reproductive rates (R0), but different generationtimes. In what ways are these two populations similar and different?
Which type of survivorship curve is generally exhibited by honeybees given their life history strategy? Type I Type II Type III
Hoverflies use Batesian mimics (they exhibit a characteristics of a dangerous species although they are harmless species to avoid predators) of a group of stinging, yellow & black-striped bees and wasps, which are Mullerian mimics (they exhibit similar characteristics of similar species to themselves to avoid predators) of each other. Assuming predators learn to avoid yellow and black insects only through experience, draw the expected relationship between the ratio of Batesian mimics to Mullerian mimics in the community (x-axis) and the probably that mimicry will successfully protect against predation (y-axis).
A population is solely comprised of 56 A2A2 individuals. 9 A1A1 individuals migrate in and contribute to the mating pool. What is the frequency of A1A2 individuals in the offspring? Answer to 2 decimal places.
true/false 1. Pitfall traps are designed to collect ground dwelling insect as well as flying arthropods. 2. Bark beetles construct characteristic galleries, which are useful for species identification. 3. Asian longhorn beetles attack many healthy coniferous trees.
I need help identifying which assumption of Hardy-Weinberg equilibrium is most affected, then indicating whether what is being described will act to establish or violate equilibrium, and lastly, whether the statement will increase or decrease that population’s genetic variation. Corals synchronize spawning to occur on a single night during a particular tidal event, such as a spring tide. On that night individuals release sperm and eggs into the water, which then form zygotes. Larvae are carried off by currents and settle elsewhere. What assumption is this breeding style affecting and what will it do to VG of that coral species?
