Test Bank for Campbell Essential Biology, 7th Edition - Page 11 preview image101.3Scenario QuestionsPlease use this information to answer the following question(s).The collared lizard is a species found in the Desert Southwest. Male collared lizards showconsiderable color variation, ranging from brightly colored to a very dull pattern. Your goal is todetermine the function, if any, of male color patterns in collared lizards, using the scientificmethod. Your tentative explanation is that male color plays a role in attracting females formating purposes. You predict that females will preferentially choose brightly colored males overdull-colored ones. To test your prediction, you observed the interactions of female collaredlizards with their male counterparts. You selected males that were the same age and size, and thatdiffered only in their coloration pattern. You placed equal numbers of the two types of malelizards, bright and dull, in aquariums, along with one female lizard per aquarium. Out of 350aquariums observed, the female chose to mate with the brightly colored male 277 times, and thedull-colored male 70 times. In three 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 thex-axis.On they-axis, plot the frequency with which each type of male was chosen by females. Usingthis graph, answer the following questions.1) Do the data support the conclusion that female collared lizards prefer more brightly coloredmale lizards over dull-colored males?A) Yes, this conclusion is supported by the data.B) No, this conclusion is not supported by the data.C) The data does not clearly indicate a preference one way or the other.Answer: ATopic: 1.1 The Scientific Study of LifeSkill: Evaluate/CreateLearning Outcome: 1.3Global LO: 2, 3, 4, 92) Dull-colored males were used in this experiment to ________.A) serve as a comparison (control) group to the brightly colored males.B) be sure that females could recognize the gender of the other lizards.C) give the experiment more trials so that the data would be more persuasive.D) be sure all females had a male with which they could mate.Answer: ATopic: 1.1 The Scientific Studyof LifeSkill: Evaluate/CreateLearning Outcome: 1.2Global LO: 1, 2, 9

Test Bank for Campbell Essential Biology, 7th Edition - Page 13 preview image12Scenario:Kenneth and Catherine Lohmann of the University of North Carolina explored the orientation ordirection-finding abilities of loggerhead sea turtlehatchlings under varying magnetic conditions.Hatchlings were placed in a tank of water in a laboratory either in the natural magnetic field ofthe earth OR in a reversed magnetic field in which north and south were flipped. The researchersthen measured the direction that the hatchlings swam. The experiments were carried out in thedark and at night since that is when most newly hatched turtles migrate from their sandy nestsinto the ocean.7) What is the variable being tested in this experiment?A) timeof dayB) amount of lightC) magnetic fieldD) time of hatchingAnswer: CTopic: 1.1 The Scientific Study of LifeSkill: Apply/AnalyzeLearning Outcome: 1.3Global LO: 1, 28) What can be tested with this experimental design?A) Turtles only hatch atnight.B) Hatchlings prefer sandy beaches to rocky beaches.C) Hatchlings have the ability to orient using magnetic fields while swimming.D) While crawling across the beach, hatchlings use the earth's magnetic field to find the sea.Answer: CTopic: 1.1 The Scientific Study of LifeSkill: Evaluate/CreateLearning Outcome: 1.3Global LO: 1, 2, 3, 99) In the experiment, hatchlings swam in one direction when exposed to the natural magneticfield of the earth, but in a different direction when exposedto the reversed magnetic field? Whatconclusion can be drawn from this?A) The orientation of turtle migration is unrelated to the magnetic field.B) It is now proven that all turtles use an inborn magnetic compass to orient their migration.C) Turtle hatchlings can detect magnetic fields.D) Hatchlings orient differently according to the direction of a light source.Answer: CTopic: 1.1 The Scientific Study of LifeSkill: Evaluate/CreateLearning Outcome: 1.4Global LO: 1, 2
