ello, I need help answering number 29(INCLUDING THE SUB-PARTS) true or false questions. Pls and thank you! 29. A.)T / F - An increase in fitness due to natural selection depends on whether fitness is genetically variable in the population. B.) T / F - The first enzymes that evolved on earth were probably ribozymes (RNA that has catalytic functions). C.) T / F - The “Cambrian explosion” involved a great diversification of animal body plans that also included primitive chordates.

Hello, I need help answering number 1 (INCLUDING SUB-PARTS) true or false questions. Pls and thank you! 1. A.) T / F - All evolutionary responses to natural selection involve a genetic change. B.) T / F - If character polarity is not correctly determined, it is impossible to make a cladogram that matches the true evolutionary history of the group studied. C.) T / F - Endangered species whose effective population size (Ne) remains small for many generations will mainly evolve by adaptive evolution.
https://evolution.berkeley.edu/evolibrary/news/110301_pcbresistantcod (ARTICLE LINK) QUESTIONS: 1. Review the process of natural selection. Use the steps to explain how PCB resistance became so common among tomcod in the Hudson. Be sure to include the terms mutation, fitness, selective pressure, and adaptation in your explanation. 2. In this blog post, the author describes the tomcod as "a quick learner" because of the population's adaptation to PCBs. Is "learning" an accurate way to describe the change in the Hudson River tomcod population? Why or why not? 3. The data shown on the map above support the hypothesis that natural selection for PCB resistance has occurred among tomcod in the Hudson. What sort of evidence regarding gene frequencies in different populations would argue against this hypothesis (i.e., imagine what the scientists would have observed in this study if natural selection on the AHR gene had not occurred among Hudson River tomcod)? 4. Why is it not accurate to…
Applying your knowledge of genetics, natural selection and evolution, how is the positive response to global climate change possible? Is your answer supported by the information from the article “Can Evolution outrace Climate Change”? According to the authors of this article, what are the conditions necessary for an organism to evolve to accommodate climate change?
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.…

Hello, I need help answering number 34(INCLUDING THE SUB-PARTS) true or false questions. Pls and thank you! 34. A.) T / F: Both negative frequency-dependent selection and positive frequency-dependent selection act to maintain genetic polymorphism. B.) T / F: The mass extinction at the end of the Cretaceous caused the extinction of all non-avian dinosaurs. C.) T / F: Natural selection can occur without any evolution in the next generation if individual differences in the trait are not heritable.
