Page 2 GO ON 1 Within a population of field mice, some individuals have brown fur and some have white fur. How would the population be affected if a change in the environment causes natural selection to favor the white-furred mice? A The brown-furred mice would begin to grow white fur. B The white-furred mice would kill off the brown-furred mice. C The brown- and white-furred mice would begin to produce more offspring with white fur. D The brown-furred mice would be less likely to survive to produce offspring with brown fur. 2 The study of the fossil record provides evidence of evolution and common ancestry. A very large fraction of all fossils discovered have been found in sedimentary rock. This rock is deposited in layers, one on top of the other. The fossils are embedded within the different layers. In sedimentary rocks, fossils in the lower layers represent fossils that are _______________ fossils in the upper rock layers. F the same age as G more closely related H younger than J older than Page 3 GO ON 3 Look at the diagram provided below. Thick arrows indicate the order of the cell(s) in the diagram. Which statement is false of what is being depicted as occurring? A The phase labeled as A illustrates the final stage of mitosis called Telophase. B The diagram illustrates phases of cell division. C The phase labeled as B illustrates the final stage of cell division, cytokinesis. D The items labeled as C are centrioles and the items labeled as D are chromosomes. Page 4 GO ON 4 A certain species of rabbit has either white (F) or brown fur (f) and either a round (T) or square tail (t). White fur is dominant to black fur and a round tail is dominant to a square tail. A cross is performed with one rabbit that is homozygous dominant for both traits and a second rabbit that is homozygous recessive for both traits. If one offspring is picked at random, what is the most likely genotype that it will have? F The rabbit will be homozygous dominant for both traits. G The rabbit will be homozygous dominant for fur color, but heterozygous for tail shape. H The rabbit will be heterozygous for both traits. J The rabbit will be heterozygous for fur color, but homozygous dominant for tail shape. Page 5 GO ON 5 Look at the food chain on the right. Which of the following statements about the movements of energy in the food chain is TRUE? Assume that there are no other organisms in this ecosystem. A Most of the energy the deer obtains from the shrubs is passed onto the wolves later. B Energy must pass to the shrubs before it can be obtained by the deer. C When they die, the energy in the deer return to the shrubs. D The only relationships between the wolf and the sun is that the wolf can obtain energy directly by sunning itself. Page 6 GO ON 6 To the right is a picture of two organisms that have an ecological relationship. Use this picture and the information below to answer the question that follows. Ants collect food on the forest floor. Sometimes, an ant will pick up fungus cells while scavenging. The fungus grows inside the ants, releases chemical signals, and eventually takes over the ant's behavior. The ant climbs onto the underside of a leaf and latches on. As the ant dies, the fungus produces a spore-bearing stalk. The spores are released and fall below to be picked up by new ants. What relationship exists between the ants and the fungus? F commensalism G parasitism H mutualism J predation Page 7 GO ON 7 An illustration of a eukaryotic cell is shown below. Which of the following letters designates a component that should also be included in an illustration of a prokaryotic cell? A E B D C C D A 8 Which of the following is NOT a true statement about the process of DNA replication? F DNA replication is needed so that a new cell receives a copy of the DNA. G DNA replication occurs within the nucleus of the cell. H Each new double helix of DNA contains one strand from the original molecule and one newly created stand. J In the last step DNA replication, the two strands of DNA "unzip." Page 8 GO ON 9 The basic structure of a DNA molecule is shown in the diagram below. What DNA component is represented by the gray pentagons in the diagrams? A ribose sugar B nitrogenous base C deoxyribose sugar D phosphate group Page 9 GO ON 10 The scenario below is best described by the interaction of what three body systems? F X- respiratory system Y- circulatory system Z- reproductive system G X- circulatory system Y- nervous system Z- immune system H X- circulatory system Y- immune system Z- muscular system J X- muscular system Y- digestive system Z- circulatory system 11 What body function is identified in the process described below? A regulation of body temperature B absorption of nutrients C defense D reproduction Page 10 GO ON 12 The diagram below represents an example of how the body regulates itself. This diagram describes what relationship in body systems? F The circulatory systems and nervous system interact to absorb nutrients. G The circulatory system and digestive system interact to defend the body from diseases. H The circulatory system and nervous system interact to maintain homeostasis. J 13 The nervous system and immune system interact for reproduction. When one side of a plant is not getting enough light, a hormone is produced in the shoot system causing growth on the darker side of the plant. This growth on the darker side causes the plant causes the plant to bend. This is an example of: A a plants' ability to reproduce B uptake of water through the plant's root system C defense from possible predators D a plants' ability to respond to its environmental conditions Page 11 GO ON 14 Which of the following words describes a form of a gene that controls a characteristic? F chromosome G trait H allele J 15 phenotype The cell cycle, including mitosis and cell division, is important to all organisms. What life function occurs as the result of mitosis in unicellular organisms? A production of gametes B reproduction C growth, maintenance, and repair D nutrient and waste exchange Page 12 GO ON 16 Describe how the transport system of a plant is critical to its reproductive function. F I and II only G II and III only H I and III only J 17 I, II, and III A deer hears a predator approaching and begins to run for safety. The deer has primarily engaged what body systems to escape? A immune, muscular, and endocrine systems B muscular, digestive, and immune systems C respiratory, endocrine, and excretory systems D nervous, respiratory, and muscular systems Page 13 GO ON 18 The sequence of events below best describes what biological concept? F primary ecological succession G nitrogen cycle H secondary ecological succession J homeostasis Page 14 GO ON 19 A bacteriophage is a virus that utilizes bacteria as host cell. The diagram below shows the lysogenic cycle, part of the reproductive process of bacteriophages. What occurs in step 2 in the diagram? A The host cell divides and new daughter cells contain viral genome. B Viral DNA is injected into the host cell. C Viral DNA is replicated and used to synthesize viral proteins. D The host cell releases a virus into the environment. Page 15 GO ON 20 The food web for a pond ecosystem is shown below.

Due to independent assortment, the possible allele combinations that could be found in gametes produced by meiosis are — A Bb, Dd, BB, and DD B BbDd and BDbd C Bd and bD D Bd, BD, bD, and bd Page 18 GO ON 24 According to the diagram, the lemur is most closely related to the — F ape G new world monkeys H lorises J tarsiers Page 19 GO ON 25 The arctic hare on the left and the jack rabbit on the right are adapted to live in very different types of environments.
