Which of the following statements is NOT an observation or inference on which natural selection is based? Group of answer choices Only a fraction of an individual’s offspring may survive. Species produce more offspring than the environment can support. There is heritable variation among individuals. Modifications of an organism acquires during its lifetime can be passed to its offspring.
Which of the following BEST describes the theory of natural selection? Living organisms change over time. Each species produces many more offspring than can survive long enough to reproduce. The offspring that do survive contain genes that are inherited from the parents. There is variation among the members of a species. Some of this variation is genetically determined and so can be passed on to future generations. Some individuals have genes that increase their chances for survival and reproduction. These individuals are more likely to reproduce and pass on their genes, causing their genes to become more common in the next generation. There is a struggle for existence among the members of a population.
Which the following statements about Darwin's theory of natural selection is true? O In order to reproduce more successfully, an individual must evolve so that it adapts to its environment. The natural environment consistently causes variation of certain traits in the population. O Individuals with inherited traits that are better suited to the local environment are more likely to survive and reproduce than less well-suited individuals. Natural selection, by its cumulative effects over long periods of time, could have caused random changes in ancestral species, thus giving rise to two or more descendant species.
Which of the following statements about natural selection is not true? O Natural selection operates according to differential reproductive success of individuals. O Natural selection usually predominates in small population only. O The cumulative effects of natural selection gives rise to individuals that can survive in a specific environment. O Natural selection results in evolution when individuals with higher survival and reproductive rates pass on these traits to their offspring.
Which one of the following would be considered an example of sexual selection? Similar death rates due to disease in both sexes of a species The presence of both male and female reproductive structures within each individual of a species Longer tailed males of a bird species mating more frequently on average than shorter tailed males of the same species Higher offspring survival in individuals homozygous for one type of allele compared to individuals homozygous for a different allele at the same locus The ability of a species to utilize either asexual or sexual reproduction
Which of the following is NOT principle of Darwinian evolution? OOffspring resemble their parents more closely than unrelated individuals. Darwinian evolution fully describes where all living things come from. O In any given environment, some individuals are more successful at surviving and reproducing than others. There is variation in morphology, physiology, and behavior among individuals in a population.
In order for natural selection to occur, organisms must (select all that apply) have a variation that can be passed from one generation to the next. have differential reproductive success. survive longer than another organism. have adaptations to their environment.
Natural selection occurs when which of the following conditions are met? Individual organisms depend on each other to obtain available resources • Variations between individual organisms lead to differential survival chances Habitat and nutrient resources in an area are plentiful over a long period of time The conditions in an ecosystem support a wide range of living organisms
Which of the below is NOT a component of natural selection? Group of answer choices Differential reproduction generated by human breeding. Variation is heritable. Variation among individuals. Differential reproduction among phenotypes.
Which of the following is NOT one of Darwin's postulates? Individuals in a population will have different versions of phenotypic traits Individuals in a population will vary in how successful they are with respect to survival and reproduction Some phenotypic traits can be passed from parent to offspring Individuals change in response to the environment, and pass those changes on to the next generation
Which of the following does not characterize natural selection? * Some parts disappeared when not in used No answer Natural resources are limited and competition occurs Survival of the fittest All living things have the potential to produce large number of offspring
Natural selection results in the adaptation of organisms to the circumstances of their way of life and their environment True or False
