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
Describe natural selection and give an example of natural selection at work in a population. Please elaborate or explain in 10-15 sentences, please?
Describe the process of evolution and articulate how this process work using one example of your choice."
Choose one of the misconceptions and explain the misconception and how discuss how your understanding on this misconception has developed over time. 1. "Scientific understand is unchanging." 2. “All mutations have an impact on the organism.” 3. “Natural selection involves organisms trying to adapt.” 4. “Adaptations are a result of competition.” 5. “There are more consumers than producers.” 6. "People look more like one parent than the other because they get more DNA from that parent."
ln three to five sentences, construct an argument for the claim that natural selection leads to evolution. Provide evidence for this claim, and be sure to explain how an organism shows the four parts of the process of natural selection. You may use any organism with the exception of bacteria and antibiotic resistance.
Write a concluding paragraph that goes through the five steps of natural selection: THESE ARE THE FIVE STEPS 1. Genetic variation 2. Survival pressure 3. Advantageous trait helps individuals to survive 4. Individuals with trait produce more offspring 5. Trait becomes more common over many generations
Write true if the statement is true or false if the statement is false. 1. As recently as 200 years ago, many people believed that Earth was only 6,000 years old. 2. Artificial selection occurs when nature selects for beneficial traits. 3. The individual Galápagos Islands are all similar to each other. 4. Malthus argued that human populations grow faster than their resources. 5. Lamarck was one of the first scientists to propose that species evolve by natural selection. 6. Lyell was one of the first to say that Earth must be far older than most people believed. 7. Lamarck's inheritance of acquired characteristics is has become a widely accepted scientific theory. 8. Fossils proved to Darwin that species can evolve. 9. The term fitness to refer to an organism's ability to outrun its hunters. 10. Darwin published his findings soon after returning to England from the voyage of the Beagle. 11. According to Darwin, natural selection is what occurs, and evolution is how it happens. 12.…
Please explain what is natural selection and how it affects the gene pool.
Please provide the difference and similarites between the following and also provide explanation for each part. a. Population and gene pool b. Random mating and inbreeding c. natural selection and genetic drift. d. a polymorphic trait and a polymorphic gene
Match the words. There are three phases of evolution expressed in the modern theory of evolution. First, genetic variation is produced at three levels. At the level of DNA,________ is a chemical change in the DNA molecule, which gives rise to variation. At the level of the individual organism, __________ gives rise to variation during the formation of gamete cells. At the level of the population, migration gives rise to variation. Second, there is a reduction of genetic variation by two processes. One process,_________ is the chance (or random) removal of genetic variants due to sampling error from generation to generation. It is especially effective in small populations. The other process, _________, eliminates the less fit variants (such as those less successful at avoiding predators or finding food). meiosis reproductive isolation genetic drift natural selection gene mutation
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
The offspring of better-adapted individuals are expected to make up a larger proportion of the next generation. Which mechanism of evolution best explains this event? Group of answer choices gene flow and genetic drift mutations and genetic drift mutations and nonrandom mating mutations and natural selection
