- Q1The four butterflies in the illustrations represent the offspring in the F1 generation. Which statement is best supported by the phenotypes of these offspring?The F1 generation is composed only of malesTwo of the offspring in the F1 generation will experience a spontaneous mutationThe F1 generation is the result of a dihybrid crossTwo of the offspring in the F1 generation will not be able to reproduce30sB.6.F: Genetic Combinations
- Q2The 1918 influenza epidemic killed between 50 million and 100 million people worldwide. This epidemic happened near the end of World War I. More people died from the influenza epidemic than were killed in the war. Which of the following explains why this virus was so deadly worldwide?Infected soldiers returning from the war spread the virus when they coughedMedical personnel often became ill as a result of exposure to airborne virus particlesAll of the aboveFood was scarce because of the war, so people were undernourished, and their immune systems were weakened30sB.4.C: Viruses
- Q3The amount of energy the producers in this energy pyramid provide the primary consumers is 54,000 joules. From this amount, 540 joules are provided to the tertiary consumers. Based on this model, how much of the energy was provided to secondary consumers?54 J540 J53,460 J5,400 J30sB.12.C: Flow Of Matter & Energy
- Q4The survival of a species depends on its ability to adapt to changes in the environment. A species must be capable of surviving and reproducing despite changes to food sources, climate, or threats from predators. Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment?Mutations are the cause of disease in the speciesMutations are a source of variation in the speciesMutations are not harmful when they occur in somatic cells of the speciesMutations are always passed on to subsequent generations of the species30sB.6.E: Changes In DNA
- Q5The diagram represents one way an enzyme can be inhibited. Which statement explains the effect of an inhibitor on an enzyme?The enzyme will likely be attacked by immune cellsA substrate will be unable to attach to the enzymeThe enzyme will be unable to produce more enzymesA substrate will be able to bond with the enzyme30sB.9.C: Enzymes
- Q6Four different nucleotides are used as building blocks of DNA. Which of the following can be used to distinguish one nucleotide from another?The shape of the deoxyribose sugarThe length of the phosphate groupThe nitrogenous baseThe type of fatty acid30sB.9.A: Biomolecules
- Q7The green frog (Lithobates clamitans clamitans) is found in many parts of the United States. The table contains some information about this frog. Why does the ability to lay 1,000 to 5,000 eggs increase the fitness of the species L. clamitans clamitans?It increases the chance of the recombination of alleles, leading to genetic drift in the populationIt increases the probability that moving water will promote gene flow from one population to anotherIt increases the probability that some offspring will survive long enough to reproduceIt increases opportunities for offspring to compete for limited resources30sB.7.D: Differential Reproductive Success
- Q8Food webs such as the one shown were first used in 1927 by the animal ecologist Charles Elton. The food web below represents the feeding relationships among organisms in an Alaskan ecosystem. An environmental change that removed which of these organisms from the ecosystem would cause the most instability in the ecosystem?AukletsFoxesZooplanktonSalmon30sB.12.F: Environmental Change
- Q9During the final stages of human gestation, receptors for the hormone oxytocin increase on the smooth muscle cells of the uterus. The release of oxytocin during labor stimulates the smooth muscle tissue in the wall of the uterus. The vigorous contraction of the uterine smooth muscle helps push the baby through the birth canal so that delivery can occur. This process involves the interaction of which organ systems?Endocrine and reproductive onlyEndocrine and muscular onlyEndocrine, muscular, and reproductiveEndocrine, reproductive, and excretory30sB.10.A: Animal Systems
- Q10In the early 1900s a scientist hypothesized a link between DNA and the production of proteins in the cytoplasm. However, the fact that DNA could not be found outside the nucleus led scientists to believe that another substance was also involved in the synthesis of protein in the cytoplasm. In the 1940s scientists performed an experiment that ultimately identified the site of protein synthesis. They also identified the molecule responsible for transporting information from the nucleus to the site of protein synthesis. What was this newly identified molecule?A genemRNAATPThymine30sB.4.B: Cellular Processes
- Q11During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material —increases the genetic variationreduces the diploid number to the haploid numberreduces the probability of mutationsincreases the haploid number to the diploid number30sB.6.G: Meiosis
- Q12As a fertilized egg divides, the cells differentiate because they —metabolize sugars rapidlycontain a lipid bilayerhave specific genes activatedcan clump together30sB.5.C: Cell Differentiation
- Q13The photograph shows monarch butterflies landing on plants where there are thousands of other monarch butterflies. These butterflies feed on milkweed plants as they travel south for the winter, covering distances of 5,000 km or more each year. However, the population of these butterflies has been steadily declining over the last 20 years. What is the most likely reason the population of these butterflies has been declining?The butterflies are evolving to tolerate cold weather in the northern United States and southern CanadaThe number of milkweed plants along the butterflies’ migratory route has decreasedThe number of bird species evolving to prey on butterflies has increasedThe increase in yearly temperatures has warmed the northern habitats30sB.12.D: Long-Term Survival
- Q14Bactrian camels, dromedaries, llamas, and alpacas are all members of the same taxonomic family, Camelidae. Members of this family all have two toes, no hooves, true canine teeth, and a split upper lip. The family Camelidae originated in North America. The physical features of animals in this family and the family’s geographical origin provide evidence that all these animals —live in the same type of ecosystemhave a common ancestorexchanged DNA at some point in the pasthave slowly evolved to become herbivores30sB.7.A: Common Ancestry
- Q15Which statement best describes the relationship between the products of photosynthesis and the reactants in cellular respiration?The products of photosynthesis serve as the reactants in cellular respiration to provide chemical energy.The products of photosynthesis combine with the reactants in cellular respiration to remove ATP from cellsThe products of photosynthesis inhibit the reactants in cellular respiration in the presence of lightThe products of photosynthesis change the structure of the reactants in cellular respiration in the presence of light30sB.9.B: Photosynthesis & Cellular Respiration
