10. gene, chromosome, replicate, diversity, mutation, evolution, scientific theory, adaptation, hypothesis, heredity • generally accepted and tested scientific explanation • Scientific Theory

11. gene, chromosome, replicate, diversity, mutation, evolution, scientific theory, adaptation, hypothesis, heredity • change in a gene • mutation

12. gene, chromosome, replicate, diversity, mutation, evolution, scientific theory, adaptation, hypothesis, heredity • information about a trait that a parent passes to its offspring • gene

13. gene, chromosome, replicate, diversity, mutation, evolution, scientific theory, adaptation, hypothesis, heredity • changes in a population over time • evolution

16. gene, chromosome, replicate, diversity, mutation, evolution, scientific theory, adaptation, hypothesis, heredity • change that makes an organism better able to survive in its environment • Adaptation

17. A(n) _________________________________ is a body part that seems to be useless. • Vestigial structure

18. Sex cells are formed by the process of ________________. • Meiosis

19. A(n) _____________________ results in the death of an organism. • Lethal mutation

20. ______________ are body parts that are similar in related organisms. • Homologous structures

21. The genetic changes that are passed on in a population occur in an organism’s______________. • Gametes

22. What is adaptive advantage? • Gives organisms a greater chance of surviving because of characteristics that allow them to be more successful than other organisms

23. How are XY gametes and XX gametes alike? Different? • Alike • both gametes can develop into adult humans • Different: • XX gametes become Females • XY gametes become Males

24. What does the theory of descent with modification state? • More recent species are changed descendants of earlier species

25. How can a population’s diversity help it survive a sudden change in its environment? • Diversity enables some individuals in a population to survive sudden environmental changes because they have characteristics that enable them to adjust to the changes.

26. What is an innate behavior? • One that is inherited and does not have to be learned. It is present at birth.
