A particular population of bird exhibits variation in beak size. Several years ago, a change occurred in the environment where the bird population lives. The graph below shows how the distribution of beak size changed within the population from the point when the change occurred to the present. Which of the following best describes the change that occurred? A. The change caused individuals with larger beaks to be more likely to survive and reproduce. B. The change caused individuals with larger beaks to be less likely to survive and reproduce. C. The change caused individuals within the population to grow larger beaks. D. The change caused individuals within the population to grow smaller beaks.

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.
