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.

DON'T EXPLAIN, JUST GIVE THE ANSWER According to Charles Darwin, organic evolution is "descent with modification," which simply means Select one: A. inherited variations decline as reproductive potential is modified. B. characteristics acquired during the lifetime of an individual are passed on to all descendants of the individual. C. the fittest always impose change on the less fit. D. populations change over time.
In Darwin's theory of natural selection, which of the following is a source of evolution: a. Individuals with random mutations who die without reproducing. b. Individuals with random mutations who are able to reproduce. c. Individuals who do not vary from their progenitors. d. Intelligent and purposeful design.
The process by which evolution occurs is calleda. natural selection. b. development. c. reproduction. d. taxonomy.
Which of the following is not a fundamental characteristic of all of life on earth? a. all life includes a common chemical composition of biological molecules b. life has the ability to extract energy from the environment c. all life requires oxygen for metabolism d. life has a universal genetic code to build proteins e. all of these are fundamental characteristics of life on
A major source of evidence for evolution is to be found in the comparative anatomy of organisms. Features that look different but have similar structural origin are calleda. homologous structures.b. analogous structures.c. vestigial structures.d. convergent structures
Which of the following most likely demonstrates that classification is the basis of evolutionary relatedness? A. Organisms that share similar characteristics are impliedly understood to have common ancestors, thus having an evolutionary relationship. B. Classification is to organize organisms into groups based on their differences and similarities and evolutionary history, so as evolution changes, classification will also change C. Classification based on evolutionary relatedness always infer that all organisms that evolved similarly shares the same history. D. Homologous structures among organisms depicts the same evolutionary history or paths.
Discuss the process of evolution through natural selection. What could happen to the ecosystem and animals in ten, one hundred, or one thousand years? Is it feasible for them to continue evolving or do they eventually become extinct? Explain your answer concisely.
