- Q2Bacteria cells can be used to produce insulin for the treatment of diabetes in humans. Which best explains how the bacteria cells are able to produce insulin for humans?The bacteria have been grown on a petri dish containing sugar; the bacteria produce insulin in response to the sugar.The bacteria have been grown on a petri dish containing insulin.The bacteria have been exposed to radioactivity to create mutant strains capable of producing insulin.The bacteria have been genetically engineered to contain the DNA needed to produce insulin.60s
- Q3____ are produced when DNA from another species is inserted into the genome of an organism, which then begins to produce the protein encoded on the recombinant DNA.plasmidstransgenic organismsvectorsgene guns60s
- Q4Which two bear species are most closely related?Bear 1 and Bear 3Bear 2 and Bear 3Bear 1 and Bear 2There’s no way to tell60s
- Q5Mr. Jones was killed in a car accident. Afterwards, a former girlfriend filed a paternity suit claiming that Mr. Jones was the father of her child, and thus she was entitled to the man’s estate. Which sample of DNA would have to be from Mr. Jones if he were the child’s father?452360s
- Q6Which of the following statements best explains why some mosquitoes survived after the first spraying?All mosquitoes had a genetic mutation that made them resistant to the insecticideNone of the mosquitoes had a genetic mutation that made them resistant to the pesticideMosquitoes flew in from different areas to help outSome mosquitoes had a genetic mutation that made them resistant to the insecticide60s
- Q7Genetic engineering is the artificial manipulation, modification, and recombination of what class of naturally occurring chemical compound?PhosphatesAmino acidsLipidsNucleic acids60s
- Q8Lamarck’s ideas about evolution include the concept that differences among the traits of organisms arise as a result ofhe natural variations already present within the population of organisms.an unchanging local environment.continual increases in population size.the actions of organisms as they use or fail to use body structures.60s
- Q9Sickle-cell anemia is associated with a mutation in the red blood cells that changes the shape. Scientists think this is an evolutionary response to exposure to malaria. People who are heterozygous for this allele are less likely to get malaria if they are bitten by a mosquito carrying the disease. This change in variation is called a..ResponseMutationPhenotypeMigration60s
- Q10Antibiotic resistant strains of bacteria are on the increase, according to data from the Center for Disease Control (CDC) in Atlanta. Which of the following best provides a description for antibiotic resistance?Drug failureSexual reproductionNatural selectionChanges in the whole DNA60s
- Q11A study published by a team led by the U.S. Geological Survey (USGS) revealed the movement of polar bears toward areas with more persistent sea ice. The researchers defined four general polar bear population clusters: Eastern Polar Basin, Western Polar Basin, Canadian Archipelago, and Southern Canada. By looking at the genes of the polar bears, they found that the polar bears have recently begun to move in a northward direction, from Southern Canada and Eastern Polar Basin into the Canadian Archipelago. The team of researchers hypothesized that the Canadian Archipelago will be a future refuge for polar bears if climate change continues to trend toward a warmer climate.variationmutationgene flowgenetic modification60s
- Q12It has been observed that organisms on islands are different from, but closely related to, similar forms found on the nearest continent. This is taken as evidence that ...island forms and mainland forms have identical gene pools.island forms are descended from a common ancestor from the mainland.common environments are inhabited by the same organisms.the island forms and mainland forms are converging.60s
- Q13Which of the following evolutionary forces can introduce new genetic variation into a population?natural selection and non-random matingnatural selection and genetic driftmutation and gene flowmutation and genetic drift60s
- Q14Which statement correctly explains how resistance to penicillin appeared after a few years of its widespread use to fight bacterial infection?some bacteria were resistant to penicillin and their population spread rapidly, without competition from bacteria that were killed by penicillinpenicillin never really successfully wiped out populations of bacteria, scientist did not use proper controls in their studiesin order to survive exposure to penicillin, bacteria developed a resistance to the druga few bacteria became resistant to penicillin, and through sexual reproduction , most bacteria acquired the resistance60s
- Q15Which of the following statements about gametes are true? I. In sexual reproduction, each parent provides genetic material for the formation of either an egg or a sperm cell. II. Gametes are produced by mitosis. III. If a sexually reproducing organism is diploid, the gametes are haploid.I and IIII and IIII, II, and IIII and III60s
