Which of the following best describes natural selection? O It is a guess made by scientists about how life develops, but it has no hard evidence to support it. It is the idea that the strong survive and the weak die off. It is the idea that organisms with genetic traits that improve their ability to reproduce are more likely to pass those traits on to future generations. It is the idea that organisms naturally increase in complexity and intelligence with time.

Which of the following is true about natural selection? Group of answer choices it acts on individuals it typically does not involve changes in genotype frequencies in a population it involves individuals willfully changing their genotype and/or phenotype in order to become better matched to their environment and leave more offspring it is a random process it involves humans increasing the frequency of desirable traits in a species by selecting which individuals breed
1) What does the term Natural Selection mean? Select one: a.The number and relative frequency of alleles present in a particular population. b.The process through which individuals with certain traits tend to produce more surviving offspring that individuals without those traits. c. Any change in the hereditary material of an organism.
Evolution has two core principles: Natural selection and A Survival of the Fittest Descent with Modification Mutations D Genetics
Identifying genes like HMGA2 is important, because it is evidence of natural selection. How does it demonstrate that natural selection occurred in Darwin’s finches? Scientists mutate and modify the gene in the lab to see how changes might occur to the organism. Scientists identify different forms of the gene in individuals from the same species and observe how it shows up as a trait. Scientists study similar genes that also impact the same traits to see how they work together and influence one another. Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment. Need some help on this one.
Which is the true statement about natural selection? O natural selection can cause some traits to become less frequent in a population over generations O natural selection causes random changes in trait frequencies in a population O natural selection can cause new versions of a trait to appear all the statements are correct
Which of the following is NOT one of Darwin's postulates? Individuals in a population will have different versions of phenotypic traits Individuals in a population will vary in how successful they are with respect to survival and reproduction Some phenotypic traits can be passed from parent to offspring Individuals change in response to the environment, and pass those changes on to the next generation
A farmer wants to make a better corn plant that produces more and bigger kernels. In the chart, information is provided on two ways organisms can change over time. Natural Selection Selective Breeding Humans are not involved in the evolution process Human intervention is involved More generations are involved in natural selection, so it is a slower process Selective breeding is a faster process Survival of the fittest increases species' chance for survival Adaptations may not necessarily improve survival Mutations that result in natural selection occur randomly The desirable charactenstics are artificially chosen What is the best way for the farmer to improve his crop and why? Use evidence from the table to support your reasoning. Please write in complete sentences.
Which of the following is the hypothesis that individuals who possess favorable traits are more likely to survive and reproduce than those who possess less favorable traits? genetic drift gene flow mutation natural selection
Which of the following are accurate descriptions of natural selection? Select all that apply. •It selects for traits that increased the complexity of the organism . ��It creates genetic variation. •It creates physical variation. •It selects for traits that helps organisms reproduce most successfully.
Natural selection usually acts on : Genes Individuals The species All of the above
