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 contribute to keeping low-fitness alleles in our gene pool? Choose all that are correct Random mating Efficient selection against rare recessive disease-causing alleles New mutations Late age of onset of some diseases Inefficient selection against rare recessive disease-causing alleles
Which statement is accurate about natural selection? It is a biological process that prevents species from adapting to significant changes in their environments. It is a biological process that leads a population to have a widespread expression of an advantageous trait. It is a biological process that allows a population to have a competitive advantage in many environments. It is a biological process that causes certain traits to be expressed less with each subsequent generation.
Natural selection and artificial selection or selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. Changes in genetic traits have occurred over generations through both natural selection and selective breeding although the occur through different means. What characterizes only artificial selection? Choose all that apply. A) chickens that lay larger eggs are favored B) selection increases the chances of surviving C) selection make a species stronger and fit for survival D) selection favors the desired characters in the new organisms
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
Natural selection is based on all of the following except individuals who survive longer tend to have more offspring than those who die young genetic variation exists within populations Individuals adapt to their environments and, thereby, evolve populations tend to produce more offspring than the environment can support the best adapted individuals tend to reproduce more
In order for a trait to evolve via natural selection, which of the following must be true regarding the trait? (this is a multiple answer question - so select all correct) Group of answer choices There must be variation in the trait. The trait must make the organism survive longer than organisms with different traits. The trait must confer a reproductive advantage on the bearer of the trait. The trait must be heritable. The trait does not necessarily need to be passed down to offspring.
Meaningful evolution occurs when __________. ○ a heritable trait affects survival and fitness ○ a heritable changed trait gives an organism a fitness advantage ○ a changed trait gives an organism a disadvantage ○ environmental factors change
What is meant by the following statement? "When mutation is random, natural selection is not." Mark all correct answers Group of answer choices A. A mutation is caused by changes in the environment. B. Natural selection can favor some mutations and not others. C.Mutations for advantageous traits are more likely to be passed on to the next generation. D.Selection can change depending on the environment.
In which of these examples can natural selection act on a trait and cause the population to evolve? A population that is faced with extinction but has no genetic variation A population where a lot of individuals have mutations, but none of the mutations relate to fitness A population with no genetic variation, but where individuals have very high numbers of offspring A population where a few individuals have mutations that allow them to develop traits for producing more offspring than other individuals
Which of the following is true about natural selection? Group of answer choices it acts on individuals it typically does not involve changes in genotype frequencies in a population it involves individuals willfully changing their genotype and/or phenotype in order to become better matched to their environment and leave more offspring it is a random process it involves humans increasing the frequency of desirable traits in a species by selecting which individuals breed
Fill in the blanks below. Write the letter of the correct definition in the blank space on the left. ______ adaptation a. inherited characteristic that increases chances of survival 2______ competition b. organisms with traits well suited to their environment survive and reproduce at a greater rate than less well-adapted organisms in the same environment 3______ natural selection c. a growing population causes a scarcity of resources 4______ gene d. change in a DNA sequence 5_____ mutation e. a segment of DNA that codes for the production of a protein Evolutionary Evidence: Write the letter of the correct definition in the blank space on the left. ______ vestigial structure a. remains of dead organisms ______ homologous structures b. structures…
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…
