This question is regarding the weight shift equation. You may use your iPad for this question to reference the POH if you choose to do so. Assume your takeoff weight is: 2266.20 lbs and your takeoff CG is: 88.51. You decide to bring with you an observer that weighs 160 lbs (rear seat). Use the appropriate weight shift equation and recalculate the new takeoff weight and balance. What is the new takeoff weight? [BLANK-1] What is the new CG? [BLANK-2]

Most Swiss starlings (birds) produce four to five eggs in each clutch. Starlings producing fewer or more than this have reduced fitness. Which of the following terms best describes this pattern?

Which of the following is most likely?  An insect that is resistant to a pesticide (a chemical that kills insect pests):

The Hawaiian archipelago (collection of islands) is way out in the Pacific Ocean.  This chain of islands was created by a volcanic “hotspot” that formed each island over many millions of years.  Soon after the newest island of Hawaii (“the big island”) rose above the sea surface (somewhat less than 1 million years ago) and organisms colonized the island, the evolution of life on this new island should have been most strongly influenced by:

Male peacocks have an extravagant (fancy) train of tail feathers, whereas female peahens lack this trait. This difference between the males and females of this species is referred to as ________.

Cotton-topped tamarins are small primates with tufts of long white hair on their heads. While studying these animals, you notice that males with longer hair get more opportunities to mate and father more offspring. To test the hypothesis that having longer hair is adaptive in these males, you should FIRST ________.

In a small population of alpine foxes, you observe increased ear length over a 10-year period. Can you definitively conclude that increase in ear length is advantageous in this population?

Large male horned dung beetles, Onthophagus taurus, use their horns as weapons in fights with rival males over ownership of breeding tunnels containing females. Females excavate (dig) tunnels beneath fresh dung (manure) piles where they mate with the males, and then lay their eggs. The use of the horns by the males in contest for the breeding tunnels is an example of: I:   intersexual selectionII:  intrasexual selectionIII: sexual selection

Darwin and Wallace’s theory of evolution by natural selection was revolutionary because it:

Claytonia virginica is a woodland spring herb with flowers that vary from white to pale pink to bright pink. Slugs prefer to eat pink-flowering plants over white-flowering plants, and plants experiencing this severe herbivory are more likely to die. The bees that pollinate this plant also prefer pink to white flowers, so Claytonia with pink flowers have greater relative fruit set (a measure of fitness) than Claytonia with white flowers. A researcher observes that the percentage of different flower colors remains stable in the study population from year to year. With no other information, if the researcher removes all slugs from the study population, what do you expect to happen to the distribution of flower colors in the population over time?
