TOPIC: The response of an HIV strain to antiviral drugs. Research your specific example of natural selection to better understand how and why the population has changed over time. Organize your information into the presentation format below. Description of inherited variation within the population Explanation of why some individuals are better able to survive and produce offspring • A description of the adaptation that is being favored by natural selection Data to support explanations
How is variation different from adaptation? * No answer Variation is always caused by mutation while adaptation is a heritable trait. Variation is a difference within an individual organism from the rest of the population. An adaptation is a feature that helps an organism survive in its environment. Adaptation is a difference within an individual organism from the rest of the population. A variation is a feature that helps an organism survive in its environment. Variations are physical or behavioral traits that make an organism better suited to its environment while adaptation comes from random mutations.
Which of the following statements about ADAPTATION are TRUE? (Identify ALL that are TRUE) Select 3 correct answer(s) Question options: Adaptations include PHENOTYPE changes within a species or population, in response to changing environment Adaptations include changes in GENE EXPRESSION within individuals, making individuals better suited to changes in environmental conditions Adaptations include GENOTYPE changes within a species or population, making individuals better suited to a particular environment Adaptations include GENOTYPE changes within a species or population, in response to changing environment Adaptations include PHENOTYPE changes within an individual, making that individual better suited to a particular environment
Explain how evolution of organisms/populations occurs as a step by step process (underline key words you know I am looking for). Include in your answer: • Evolution • Mutation • Genetic variation • Natural selection • Sexual selection • Gene drift • Gene flow • Fitness • Phenotype • Genotype
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.

Which of the following BEST explains Darwin's observation on populations of various species that seemed well-suited to their environment? * Species had been introduced to particular areas by humans on purpose. no answer Species might be able to adapt to their surroundings over time. The species Darwin saw were all related to each other. Some environments rarely ever change.
Definitions: 1. Based on the outcome of natural selection, describe four different modes of natural selection. Provide one example for each mode. Each example must be different from the ones taught in lecture and lab ppt.
Antibiotic resistance is on the rise due to greater use of antibiotics, including the use with livestock. Explain your understanding of the rise in use of antibiotics. How are antibiotics used in raising livestock? How does this pose a threat to humans? What can we learn about the process of natural selection and evolution from the antibiotic-resistant bacteria? How should this change the use of antibiotics? Your post/article should be a minimum of 500 words in length.
Remember that understanding is explanations more than facts. Definitions of phenotype, genotype, allele, gene, microevolution, macroevolution Know that in humans, most of the genetic variation is observed within populations, and know why that is. Know the 4 processes of evolution (3 neutral + natural selection) Know that evolution isn't progressive and doesn't necessarily lead to more complexity Know that evolution can lead to traits that decrease survival (ex: sexual selection) Know that quantitative traits are generally influenced by (i) many genes, each having a small effect on the trait value; and (ii) the environment What is F1 like when you cross 2 homozygotic lines of peas of different colors? What is F2 like when you cross F1 individuals (remember what 9:3:3:1 is about) Know what genetic dominance is about Definitions of chromosome, nucleus, mitosis, meiosis, crossing over How many chromosomes in humans? How many pairs of chromosomes? Know and apply Hardy-Weinberg's equation…
Directions: Write ADAPT if the statement is under the principle of Jean Baptiste de Lamarck and EVOLVE if the statement is under the principle of Charles Darwin. 1. Species may experience extinction if they are not fitted to live in their environment. 2. Species, which become extinct, just experienced evolution to fit in their environment. 3. Once a trait is developed due to adaptation in environment, it may be passed to succeeding oripnisms. 4. Habitual actions with a specific body part may lead to its changes. 5. Body parts that are of no use but still present in an organism's body are evidence for its ancestor species. 6. Animals with the same body part may have modifications depending on its physical requir. ements. 7. Changes happen in an organism for a long and uniform process. 8. A body part that is no longer used by an organism may lag from its development. 9. Birds grew web-like structure on their feet to be able to feed on the surface of water. 10. Ancestral…
