please help with these two questions: 1. Mutation, as a genetic evolutionary force is: a. A strong evolutionary force b. A weak evolutionary force c. Not considered an evolutionary force d. The most important evolutionary force in humans e. A neutral evolutionary force 2. In population genetics, we use specific terms to depict particular evolutionary processes. How does genetic drift differ from gene flow? a. Statement 3. Genetic drift is the diﬀerential transmission of alleles into the next generation due to the consequences of functional diﬀerences on an individual’s survival and reproductive success. b. Statements 1 and 2 are correct descriptions of genetic drift and gene flow. c. Statement 4. Gene flow is due to copying errors during DNA replication and transcription, which introduces new alleles into the population. d. Statement 2. Gene ﬂow spreads alleles from one population into another via migration, making them more…

EVOLUTION LINK Write short paragraphs explaining each of the following statements: (a) Natural selection chooses from among the individuals in a population those most suited to current environmental conditions. It does not guarantee survival under future conditions. (b) Individuals do not evolve, but populations do. (c) The organisms that exist today do so because their ancestors had traits that allowed them and their offspring to thrive. (d) At the molecular level, evolution can take place by the replacement of one nucleotide by another. (e) Evolution is said to have occurred within a population when measurable genetic changes are detected.
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 traits acquired during an individuals lifetime (d) natural selection acts on a populations genetic variability, which arises through mutation (e) natural selection may result in changes in allele frequencies in a population
Which statement is true? Explain your answer. A. Natural selection acts on populations, not on individuals. B. Mutations care the raw material for natural selection. C. Evolutionary change occurs at the level of the individual. D. Developmental change is a population-level process. E. Species are simply those organisms that share similar phenotypes.
The theory of evolution is most accurately described as Group of answer choices A. Nn opinion that some scientists hold about how life originated on Earth. B. An overarching explanation, supported by much evidence, for how populations change over time and new species arise from ancestral species. C. One possible explanation, among several scientific alternatives, about how species have come into existence. D. An educated guess about how species originate. E. An idea about how acquired characteristics are passed on to subsequent generations.
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?
Evolution is a theory, so it is still only tentative. Once it is really a meaningful scientific discipline, it will become a law. Select one: O True O False Darwin was meticulous in making several key observations that formed the foundation of his argument for his theory of evolution. Which of the following did Darwin NOT use in the formulation of his theory? Select one: O a. Variation exists in populations. b. There is a culling among offspring. c. Keystone species are infrequently found in disturbed communities. d. Traits are inherited across generations. e. Individuals reproduce in excess. A bison walks through a prairie, foraging on grass. As it walks, it kicks up insects which are then eaten by brown-headed cowbirds. Match the relationships below with their appropriate type of dyadic interaction. Bison Grass Choose... Choose...

Define gene mutation Group of answer choices A. the process whereby organisms better adapted to their environment tend to survive and produce more offspring. B. the introduction of genetic material (by interbreeding) from one population of a species to another, thereby changing the composition of the gene pool of the receiving population C. variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce. D. A rare and random change in a gene that can be bad or benef icial depending on the environment .
