3) kingdom, phylum, class, order, family, genus, species
4) genus, species, kingdom, phylum, class, order, family
What is a hypothesis?
1) the same thing as an unproven theory
2) a tentative explanation that can be tested and is falsifiable
3) a verifiable observation sensed directly, or sensed indirectly with the aid of scientific instrumentation
4) a fact based on qualitative data that is testable
9) A controlled experiment is one in which
1) the experiment is repeated many times to ensure that the results are accurate.
2) the experiment proceeds at a slow pace to guarantee that the scientist can carefully observe all reactions and process all experimental data.
3) there are at least two groups, one of which does not receive the experimental treatment.
4) there are at least two groups, one differing from the other by two or more variables.

10) Which of the following statements about ecology is incorrect?
1) Ecologists may study populations and communities of organisms.
2) Ecological studies may involve the use of models and computers.
3) Ecology is a discipline that is independent from natural selection and evolutionary history.
4) Ecology spans increasingly comprehensive levels of organization, from individuals to ecosystems

11) Which of the following levels of organization is arranged in the correct sequence from most to least inclusive?
1) community, ecosystem, individual, population
2) ecosystem, community, population, individual
3) population, ecosystem, individual, community
4) individual, population, community, ecosystem

12) Ecology as a discipline directly deals with all of the following levels of biological organization except
1) population.
2) cellular.
3) organismal.
4) ecosystem.

13) You are working for the Environmental Protection Agency and researching the effect of a potentially toxic chemical in drinking water. There is no documented scientific evidence showing that the chemical is toxic, but many suspect it to be a health hazard. Using the precautionary principle, what would be a reasonable environmental policy?
1) Establish no regulations until there are conclusive scientific studies.
2) Set the acceptable levels of the chemical conservatively low, and keep them there unless future studies show that they can be safely raised.
3) Set the acceptable levels at the highest levels encountered, and keep them there unless future studies demonstrate negative health effects.
4) Caution individuals to use their own judgment in deciding whether to drink water from a potentially contaminated area.

14) Which of the following abiotic factors has the greatest influence on the metabolic rates of plants and animals?
1) water
2) wind
3) temperature
4) rocks and soil

15) All of the following would have a direct effect on the amount of precipitation in an area except
1) air circulation cells.
2) continental drift.
3) ocean currents.
4) mountain ranges.
16) In temperate lakes, the surface water is replenished with nutrients during turnovers that occur in the
1) autumn and spring.
2) autumn and winter.
3) spring and summer.
4) summer and winter

17) Which of the following causes Earth’s seasons?
1) the tilt of Earth’s axis
2) global wind patterns
3) ocean currents
4) changes in Earth’s distance from the sun

18) Polar regions are cooler than the equator because
1) there is more ice at the poles.
2) sunlight strikes the poles at an oblique angle.
3) the poles are farther from the sun.
4) the poles have a thicker atmosphere.

19) If a meteor impact or volcanic eruption injected a lot of dust into the atmosphere and reduced the sunlight reaching Earth’s surface by 70% for one year, all of the following marine communities most likely would be greatly affected except
1) deep-sea vent communities.
2) coral reef communities.
3) benthic communities.
4) pelagic communities.

Use the following information to answer the questions 20 and 21.

When a female cat comes into heat, she urinates more frequently and in a large number of places. Male cats from the neighborhood congregate near urine deposits and fight with each other.

20) Which of the following is a proximate cause of this behavior of increased *********?
1) It announces to the males that she is in heat.
2) Female cats that did this in the past attracted more males.
3) It is a result of hormonal changes associated with her reproductive cycle.
4) The female cat learned the behavior from observing other cats.

21) Which of the following would be an ultimate cause of the male cats’ response to the female’s
