- Please help with the following: Prior to approximately 12 KYA, humans were hunter-gatherers and relied on wild plants and animals for subsistence. This means that their conscious manipulation of the genomes and gene pools of other organisms was essentially non-existent. 12KYA signaled the beginning of plant and animal domestication efforts. A. Two true statements; one false statement B. Two false statements; one true statement C. All True statements D. All False statements E.

- 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 .arrow_forwardWhich of the following is NOT an appropriate use of DNA Sequencing data. a. Comparing the genomes of endangered animals to protect them. b. Comparing the genomes of dog breeds to understand their evolution. c. Comparing the genomes of healthy and sick populations to understand genomic basis of disease. d. Comparing an individual's genome to other individuals in a population to determine their health risk or to eliminate them as suspects in a crime. e. Comparing populations based on socially constructed groupings to assert a hierarchy among those groups.arrow_forwardDirections: 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…arrow_forward
- Studies of opossums in Georgia have found that individuals from a population on an offshore island have longer lifespans in captivity than individuals from mainland populations. What is a reasonable explanation for this pattern? Group of answer choices a. the island opossums are vampires b. the opossums from the island have a history of being kept in captivity c. he opossums on the island have a lower metabolic rate d. there are fewer predators on the island compared to the mainlandarrow_forwardOn average, Black Americans have shorter life expectancies than White Americans. Which of the following contributes to this difference? A. In recent years, alcohol and opioid abuse have had the biggest impact on life expectancies for Black Amerians relative to any other racial or ethnic groups. B. Black Americans are more likely to have regualr cancer screenings and so have a higher recorded incidence of cancer. C. The youngest generations of Black American are less health than older generations, so health amoung Black Americans has been getting worse over time. D. Black Americans ten to receive lower-quality care and spend less time with medical practitioners than White Americans do.arrow_forwardHow is variation different from adaptation? * Variations are physical or behavioral traits that make an organism better suited to its environment while adaptation comes from random mutations. no answer 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. Variation is always caused by mutation while adaptation is a heritable trait. 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.arrow_forward
