2. A generally accepted and well-tested scientific explanation
3. The study of heredity
4. The passing of traits from parents to offspring. All organisms pass information about traits to their children.
5. A change or adjustment that makes an organism better able to survive in its environment.

5 Matching Questions

1. Homologous structure
2. Mutation
3. Meiosis
4. Lethal Mutation
5. Evolution

1. a The changes in a population over time.
2. b A change in a gene. They can cause problems in humans and other organisms.
3. c A mutation that results in the death of an organism.
4. d The process that results in sex cells. The chrmosomes are copied in the parent cell. The cell divides into two new cells. Each new cells divides again. One parent cell results in four new sex cells. Each sex cell contains one-half the number of chromosomes of the parent cell.
5. e A body part that is similar in related organisms
