Suppose a farmer puts antibiotics in meat that he leaves out for lion cubs. The antibiotics in the meat increase resistance to infections, helping the cubs survive to adulthood. Is this an example of natural selection and why? O Yes, because the variation in characteristics helps the cubs survive. O No, because there is no difference in fitness for these lion cubs. No, because this increased resistance to infections cannot be inherited. Yes, because the cubs leave more offspring than cubs that do not have antibiotics.

Mosquitoes can carry and transmit many diseases to humans. In the past, the insecticide DDT was heavily used to reduce mosquito populations in order to reduce instances of disease transmission. However, after some time, mosquito populations developed a resistance to DDT, which made the DDT less effective in reducing mosquito populations. Based on what you’ve learned about natural selection, in 3–5 sentences, describe how mosquitoes may have come to develop this resistance.

Consider Lamarck’s idea in a hypothetical situation. For example, you decided that when you have children, you want them to be big ang strong. You decided to go to the gym every day for a year. You did all your exercise routines diligently and you were able to develop really bulky and toned muscles because you believed that your kids would inherit your big impressive muscles. Do you think this would work? Justify your answer using the concepts you have learned from Genetics, as well as Darwin’s concept of evolution.
One of the lines of evidence that led Darwin to the theory of natural selection was his study of artificial selection. Plant breeders and pigeon breeders select offspring with specific traits in mind beforehand. a) However, since humans are an integral part of the natural world, do you think that artificial selection might be more appropriately termed “natural selection”? Why?
What is meant by the following statement? "When mutation is random, natural selection is not." Mark all correct answers Group of answer choices A. A mutation is caused by changes in the environment. B. Natural selection can favor some mutations and not others. C.Mutations for advantageous traits are more likely to be passed on to the next generation. D.Selection can change depending on the environment.
Which aspect(s) of natural selection is(are) illustrated by the figure below? Check ALL answers that apply. A. Variation among individuals must be genetically transmissible to the next generation. B. Variation must exist in a population. C. Variation among individuals leads to differences in lifetime reproductive success. D. More individuals are produced each generation than the environment can support, resulting in competition for survival.
Which of the following is not true of natural selection?(a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traitsacquired during an individual’s lifetime (d) natural selection Test Your Understanding acts on a population’s genetic variability, which arisesthrough mutation (e) natural selection may result in changes in allele frequencies in a population
According to Darwin’s model of evolution, evolution can only occur if there is some variation present among the individual members of a population. Which statement best describes the source of this variation among members of a species? A) variation exists because different individuals will have different access to food and other resources B) individuals will vary depending on geography and climate C) variation exists because not all genes will be affected D) variation among individuals may arise as a result of mutations in the genetic code
Which statement about natural selection is true? Natural selection only happens to animals. Natural selection produces animals fit for their environment. Evolution causes natural selection. Natural selection produces animals that are faster and stronger.
Which of the following best explains the role mutations play in natural selection?A. Most mutations are negative and result in the extinction of the entire speciesB. Mutations may appear for one or two generations, but they usually disappear quickly.C. If the environment changes, an existing organism develops a mutation that will help them to survive.D. Some mutations give individuals an advantage in their environment, allowing them to survive and reproduce.D is my answer is it correct?
Which of the following is NOT a characteristic of natural selection? a) Variation exists among individuals in a population b) Some individuals are better adapted to their environment than others c) Organisms evolve to fit a predetermined goal or plan d) The better-adapted individuals are more likely to survive and reproduce
Natural selection allows certain species to survive. The organisms that survive are those best adapted to their environment. Does natural selection make organisms more complex and perfect?
