Biomedical scientists study species as different as worms, fruit flies, mice, zebrafish, or rhesus monkeys to understand human genes and how they lead to diseases. Why? undefined Because they make up an interconnected food web when bacteria are added.Because these species have many inherited features that are very similar to our own.Because rhesus monkeys gave us the Rh+ factor when they bit our ancestors.Because these species are all prokaryotes, and therefore their genes are 99.9% identical to one another. undefined undefined17. Why are most food chains limited to 3 to 5 trophic levels?undefined The higher the trophic level, the larger the organism; the larger the organism, the less likely it will be prey.The nutritional quality of existing biomass decreases with increasing trophic level.Most ecosystems have insufficient space to support the increased number of organisms that more trophic levels would require.There is insufficient energy to support more trophic levels. undefinedundefined18.

What is one way in which energy flow differs from chemical cycling?undefined Energy flow is unidirectional; chemical elements can be recycled.Energy can enter but cannot leave an ecosystem; chemical elements can leave but cannot enter an ecosystem.Energy flows from lower to higher trophic levels; chemicals cycle from higher to lower trophic levels.Energy can both enter and leave an ecosystem; chemical elements always remain within a single ecosystem. undefined undefined21. Why do some scientists argue that viruses are non-living?undefined Viruses are able to reproduceViruses evolveViruses are not made of cellsViruses have an organized and complex structure undefined22. Which of the following activities decreases greenhouse gases in the atmosphere?undefined Cutting down trees.Driving gasoline-powered vehicles.Using electricity from coal power plants.Planting trees.Heating your home with an oil furnace. undefined23. How does high heat impact most enzymes? undefined Enzyme activity is decreased due to hydrolysisEnzymes are inactivated due to denaturationEnzyme activity is increased due to saturationSince enzymes are temperature independent activity will remain the same. undefinedundefined24. Which of the following situations has the greatest potential for observer bias in an experimental study?undefined Ms McCormack is an outside consultant who is conducting a health and wellness survey for a pharmaceutical company. She neither knows the name of the company, nor the name of the drug being tested during the surveyGraduate student Jonas Brown is conducting a survey of weight loss for his professor. He asks each student in the study the same questions.Dr. Smith is analyzing biopsy examples from rats who have been given either a placebo or an experimental drug believed to reduce inflammation. Each sample is identified by a code number; therefore, Dr. Smith cannot tell which treatment each rat received.Ms Williamson is a research technician who surveys the responses to a new cold remedy by a study group. She only knows the e-mail address of each participant and asks them identical questions by computer.Dr. Jones is evaluating cancer patients for their responses to a new therapeutic drug. She knows which patients are receiving the drug and which patients are receiving the placebo. undefined25.
