Researchers at the university of georgia have evaluated trends in streamside forests in areas within roughly 400 feet of the state’s streams and rivers. a decline in streamed forests is evident across much of the state. between 1974 and 2005, 41 of the state’s 52 large watersheds showed declines in riparian forests. the greatest losses were in the upper chattahoochee, middle savannah, upper ocmulgee, and middle chattahoochee. stream-side or riparian land lies directly along rivers, streams, and other bodies of water and provide benefit to aquatic ecosystems. most specifically, stream-side forests affect the trout populations in north georgia. how?         a) trees and shrubs provide both food and shelter for the trout. tree roots provide a bedding place, while the plant life in general, is a source of nutrition.                                  b) riparian vegetation to reduce the impact of invasive species which may compete with local fish, especially trout, for the resources needed for survival.  c) trees and shrubs provide shade, which keeps the water temperature cooler. lower temperatures allow the water to hold more oxygen, which in turn creates a healthier habitat for the trout.   d) riparian vegetation traps and removes pollutants from the water. trout are particularly susceptible to water pollutants. there is a direct correlation between pollutants and trout death.

The collared lizard is a species found in the desert southwest. male collared lizards show considerable color variation, ranging from brightly colored to a very dull pattern. your goal is to determine the function, if any, of male color patterns in collared lizards, using the scientific method. your tentative explanation is that male color plays a role in attracting females for mating purposes. you predict that females will preferentially choose brightly colored males over dull-colored ones. to test this prediction, you observed the interactions of female collared lizards with their male counterparts. you selected males that were the same age and size, and that differed only in their coloration pattern. you placed equal numbers of the two types of male lizards, bright and dull, in aquariums, along with one female lizard per aquarium. out of 350 aquariums observed, the female chose to mate with the brightly colored male 277 times, and the dull-colored male 70 times. in 3 instances, the females did not mate with either type. create a bar graph of your data, plotting the type of male (dull or brightly colored) on the x-axis. on the y-axis, plot the frequency with which each type of male was chosen by females. using this graph, answer the following question(s). is it reasonable to conclude (i.e., is it supported by the data) that female collared lizards prefer more brightly colored male lizards over dull-colored males?
