What are the domains?A) Bacteria and Eukarya B) Archaea and MoneraC) Bacteria and Protista D) Bacteria and Archaea4) Which of these provides evidence of the common ancestry of all life? A) near universality of the genetic codeB) structure of the nucleus C) structure of ciliaD) structure of chloroplasts5) The phylogenetic tree below ____.A) depicts the three major domains of life B) includes unicellular but not multicellular lifeC) includes unicellular and some forms of multicellular life, but not complex animals and plantsD) includes noncellular lifeforms6) You find yourself standing next to a beautiful rose bush. Which of the following do you and the rose have in common?A) You both are multicellular. B) You both lack a membranebound nucleus.C) You are both prokaryotic. D) You and the rose have nothing in common.The following experiment is used for the corresponding question(s).
A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two distinct times of the year: early in spring when the oak trees are flowering and in midsummer when flowering ispast. Caterpillars from eggs that hatch in spring feed on oak flowers and look like oak flowers. But caterpillars that hatch in summer feed on oak leaves and look like oak twigs.How does the same population of moths produce such differentlooking caterpillars on the same trees? To answer this question, the biologist caught many female moths from the same population and collected their eggs. He put at least one egg from each female into eight identical cups. The eggs hatched, and at least two larvae from each female were maintained in one of the four temperature and light conditions listed below.In each of the four environments, one of the caterpillars was fed oak flowers, the other oak leaves. Thus, there were a total of eight treatment groups (4 environments 2 diets).7) Refer to the accompanying figure. Which oneof the following is NOT a plausible hypothesis to explain the differences in caterpillar appearance observed in this population? A) The longer day lengths of summer trigger the development of twiglike caterpillars.B) The cooler temperatures of spring triggerthe development of flowerlike caterpillars.C) Differences in air pressure, due to differences in elevation, trigger the development of different types of caterpillars.D) Differences in diet trigger the development of different types of caterpillars.8) Refer to the accompanying figure. In every case, caterpillars that feed on oak flowers look like oak flowers. In every case, caterpillars that were raised on oak leaves looked like twigs. These results support which of the following hypotheses?A) The longer day lengths of summer trigger the development of twiglike caterpillars.B) Differences in air pressure, due to elevation, trigger the development of different types of caterpillars.C) Differences in diet trigger the development of different types of caterpillars.D) The differences are genetic. A female will either produce all flowerlike caterpillars or all twiglike caterpillars.
9) Recall the caterpillar experiment in which caterpillars born in the spring looked like flowers, and caterpillars born in the summer looked like twigs. What is the most likely evolutionary advantage for this difference in body shape?A) Looking like their food sources allows the caterpillars to move through their environment more efficiently.B) Development into the adult moth form is faster for caterpillars shaped like twigs than like flowers.C) Looking like their food source lets the caterpillars blend into their surroundings,reducing predation.D) Looking like their food source will increase the caterpillars' feeding efficiency; this would increase their growth rate and survival rate.10) A friend of yours calls to say that his car would not start this morning. He asks for your help. You say that you think the battery must be dead. If so, then jumpstarting the car from a good battery will solve the problem. In doing so, you are ____.A) testing a theory for why the car will not startB) making observations to inspire a theory for why the car will not startC) stating a hypothesis and using that hypothesis to make a testable predictionD) comparing multiple hypotheses for why the car will not start11) Agrobacterium infects plants and causes them to form tumors. You are asked to determine how long a plant must be exposed to these bacteria to become infected. Which of the following experiments will provide the best data to address that question?A) Determine the survival rate of Agrobacterium when exposed to different concentrations of an antibiotic.B) Measure the number of tumors formed on a plant when exposed to various concentrations of Agrobacterium.C) Measure the concentration of Agrobacterium in different soil environments where the plants grow.D) Measure the number of tumors formed on plants, which are exposed to Agrobacterium for different lengths of time.Use the following information when answering the corresponding question(s).In 1668, Francesco Redi performed a series of experiments on spontaneous generation (Living things coming from nonliving things). He began by putting similar pieces ofmeat into eight identical jars. Four jars were left open to the air, and four were sealed. He then did the same experiment with one variation: Instead of sealing four of the jars completely, he covered them with gauze (the gauze excluded the flies while allowing the meat to be exposed to air). In both experiments, he monitored the jars and recorded whether or not maggots (young flies) appeared in the meat.12) Refer to the paragraph on Redi's experiments.In both experiments, flies appeared in all of the open jars and only in the open jars. Which one of the following statements is correct?A) The experiment was inconclusive because Redi used only one kind of meat.B) The experiment was inconclusive because it did not run long enough.C) The experiment supports the hypothesis that spontaneous generation occurs in rotting meat.D) The experiment supports the hypothesis that maggots arise only from eggs laid byadult flies.
13) Which of the following is the best descriptionof a control for an experiment?A) The control group is kept in an unchanging environment.B) The control group is identical to the experimental group except for the independent variable.C) The control group is exposed to only onevariable rather than several.D) Only the experimental group is tested or measured.14) Which level of ecological study focuses the most on abiotic factors?A) speciation ecology B) population ecologyC) community ecology D) ecosystem ecology15)Based on the data in the figure above, which of the following statements are correct?I) Area 1 would be considered a desert because of its high average temperature.II) Area 1 has more average precipitation than Area 2.III) Area 2 would be considered a desert because of its low average precipitation.IV) Area 2 has a larger annual temperature variation.A) only I and III B) only II and IVC) only I, II, and IV D) only II, III, and IV
