What is the difference between evolution, natural selection, and artificial selection?
A.
Evolution is a genetic change in a population over time which can occur through natural selection.
Artificial selection is the differential reproduction of individuals in a population to promote the characteristics chosen by the breeder.
B.
Natural selection is the change of allele frequencies in a population over time.
Evolution leads to differential survival and reproduction of individuals.
Artificial selection has produced domesticated animals and plants.
C.
Evolution is a mechanism of artificial selection.
Natural selection is a form of artificial selection in which nature selects the characteristics that are most beneficial to a species.
D.
Artificial selection is a mechanism of evolution and is the main process of domesticating animals and plants for human use.
Natural selection is the same as evolution.
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 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?

- Environments all over the world are changing as a result of global warming. Will this cause natural selection to occur? A. No.The environment is always changing. Global warming is nothing new. B. Yes, warmer temperatures will induce mutations that are favorable to survial in the new teperature regime C. No. The only change will be that species from hot environments will expand their ranges. D. Yes. Traits that help individuals produce more offspring in warmer environments will increase in frequency. E. Yes. Warmer temperatures will increase the rate of chemical reactions in poikilothemic species and thus natural selection will be enhanced.arrow_forwardDarwin’s Theory of Natural Selection occurs in 4 steps.Which of the following is NOT one of these four steps?a.
