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 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 conclusions are MOST likely to be supported by genetic evidence? A. Some modern-day organisms did not exist in the past. B. Some organisms found in the fossil record do not currently exist. C. Environmental change affected the fitness of individuals differently based on their traits. D. Some disease-causing traits may remain in a population because their alleles provide an advantage to heterozygotes.
