A student lists statements about how a species adapts to the environment. One statement needs to be edited for accuracy. 1. Variation in a species occurs from predictable mutations.
2. Variation exists in the phenotypes of the species.
3. Physical characteristics influence an organism’s ability to utilize resources.
4. Physical characteristics affect an organism’s ability to reproduce.
Which statement should be edited, and what should the change be?
A. Statement 1—Variation in a species occurs from random mutations.
B. Statement 2—Variation exists in the genes of the species.
C. Statement 3—Physical characteristics influence an organism’s ability to find resources.
D. Statement 4—Behavioral characteristics affect an organism’s ability to reproduce.

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.
