- . You are discussing the choice of the "oil-eating" bacteria that you will use to clean the affected area from the oil spill and your team wants to know whether the Kalba sea constitutes a natural habitat for these bacteria. Formulate a hypothesis stating why or why not the Kalba sea area can be considered a natural habitat for such bacteria. Support your answer by discussing the role of evolution in contributing to the survival and thriving of “oil-eating" bacteria. Explain how and why these bacteria acquired these characteristics.arrow_forwardPlace the following elements in the strategy to control mosquito populations in the correct order from earliest to latest by numbering them from 1 to 5. a. Scientists genetically modify male mosquitoes in the lab. b. Mosquito offspring produced by the matings do not survive to adulthood. c. GM male mosquitoes mate with normal wild females. d. The mosquito population decreases dramatically. e. Scientists release GM male mosquitoes into the wild.arrow_forwardMutations cause variations among individuals. If these variations provide an advantage to individuals, then the resulting traits are known as adaptations. Which of the following statements about adaptations is incorrect? A. They are structural or physiological in nature. B. They modify the behaviour of organisms. C. They provide a selective advantage in any environment. D .They increase reproductive success of organisms.arrow_forward
- Which of these statements about the virulence of rabbit myxoma virus is TRUE?A. Rabbit myxoma virus needed to become less virulent so it could coexist with its rabbit hosts.B. Directional selection favored a coevolutionary escalation where resistance evolved in rabbits and less virulence evolved in the virus.C. Rabbit myxoma virus became less virulent over time because natural selection favored strains that did not immediately kill the rabbit hosts, enhancing the likelihood of spreading and infecting other rabbits.D. None of the above is a true statement.arrow_forwardA bacterial species that becomes resistant to certain antibiotics mayhave acquired the resistance genes from another bacterial species. Thephenomenon of acquiring genes from another organism without beingthe offspring of that organism is known asa. hybridization.b. integration.c. horizontal gene transfer.d. vertical gene transfer.e. competence.arrow_forwardThe spread of antibiotic resistance genes is an example of evolution. Explain how this is evolution using the framework of natural selection. Make sure you include what genes are evolving and what is the selective agent or selective pressure.arrow_forward

They are only inherited if they occur in a sperm or egg cell.d. They often occur when DNA is copied.arrow_forwardHow is an anatomical adaptation defined? A. a system present within the organism that allows it to perform a biochemical reaction B. a feature of the organism's body that helps it survive and reproduce C. a response from the organism that changes it's behavior to help it survive and reproduce ©2003-2022 International Academy of Science.

Which statement describes a mechanism behind this trend? (A.) People’s bodies become more resistant to antibiotics after exposure to them (B.)
