Which of the following does not apply to mutations?a. They occur to cause adaptive changes in response to the environment.b. They are usually either harmful or neutral.c. They are only inherited if they occur in a sperm or egg cell.d. They often occur when DNA is copied.
Much research has been done in the cloning of animals; a tadpole in 1954, Dolly the
sheep in 1997, and the endangered gaur are just a few of the "famous" cloned
animals. However, cloning of animals has met with limited success. Which
statement is a scientific argument against the cloning of animals?
Animals on the endangered species list could be cloned, and their populations
A
would increase.
Most cloned animals have a compromised immune system and have a low
survival rate.
Cloning of animals can be beneficial in the treatment and prevention of many
diseases.
New technologies and scientific equipment have made cloning of animals safe.
The mutation rate is
a. the likelihood that a new mutation will occur in a given gene.
b. too low to substantially change allele frequencies in a population.
c. lower for mutations that create beneficial alleles.
d. All of the above are true of the mutation rate.

All of the above are true of the mutation rate.arrow_forwardConsider that you are a civilian resident living on the Chatham Island in New Zealand where a long-finned pilot whale stranding event with 100 beached whales is happening and maybe have even been participating in the response to the strandings. Raise specific questions that you may have for the local government or researchers about the stranding. Argue for an alternate hypothesis as to why the event occurred. Use and fully cite in-text peer-reviewed journals and government organizations, to support all data. Then, provide a full reference section at the end to list all the sources usedarrow_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_forward
- The best argument for how an unprotected species can evolve to mimic a second protected species (distasteful or noxious) and thus obtain protection is by A. Random changes in the appearance of the unprotected species that lead to increased fitness due to greater similarity with the protected species B. Individuals deciding that they need protection and mutating to look like the protected species C. Individuals changing their diet to increase pigment production to look like the protected species D. Natural selection for more advanced traits that are better to the inferior traits of organisms that do not look like the protected species E. Behavioral modification of the unprotected species to act like the protected speciesarrow_forwardIn a hybrid zone, reinforcement often prevents which of the following? a. Fusion b. Incipient species c. Secondary contact d. Hybrid infertilityarrow_forwardScenario C: Your Uncle raises beef cattle and is considering adding low amounts of antibiotics to their feed because he heard it makes them grow larger. Explain to him: The concept of using antibiotics for "essential use only." The process of natural selection. How low levels of antibiotics select for resistant bacteria. How these antibiotic resistant bacteria can then be harmful to not only cows, but also humans.arrow_forward
- Two parents, who are thought to be different species, mate and produce viable hybrid offspring. When two of these hybrids mate, their offspring are not viable. What is the BEST interpretation of this data? A. The original parents are the same species because they can breed together. B. The original parents are the same species because they can breed together and produce viable offspring. C. The original parents are not the same species because they produce hybrids that impair the species’ development or survival in its environment. D. The original parents are not the same species because they produce hybrids that can have reduced viability and fertility when they mate.arrow_forwardMorphological differences are abundant among many species. We make assumptions about why adaptations exist, but to understand whether a specific trait is a adaptive and why, researchers must create experiments that have all the following, EXCEPT: a. replication of each treatment to ensure reliability of results. b. experimental design that enables all full interpretation of differences. c. include control groups. d. hypotheses that are testable and falsifiable. e. exceedingly small sample sizes in each treatment group.arrow_forwardWhich of the following traits does not describe a r-selected species? A. rapid development B. low parental investment C. high reproductive rates D. short life spans E. late maturationarrow_forward
