1. , in a broad sense the science of classification, but more strictly the classification of living and extinct organisms-i.e., biological classification. The term is derived from the Greek taxis ( "arrangement" ) and nomos ( "law" ).
2. Structures are similar in appearance but not in structure
3. Which of the following is an example of homologous structures that support the theory of evolution?
4. One sex competes over obtaining mates, and only those with specific traits are successful
5. ..... are damaged DNA.
6. Both gene fusions and chromosomal fusions can have significant effects on gene expression, leading to changes in cellular processes and potentially contributing to the development of genetic diseases. These mutations are important to study in order to understand the underlying mechanisms of disease and to develop new therapies that target specific genetic abnormalities
7. Some scientists think that all life evolved from a common ancestor. Which provides evidence that this may be true?
8. Identical reproduction (starfish)
9. Structures as different as human arms, bat wings, and dolphin flippers contain many of the same bones, these bones having developed from very similar embryonic tissues. How do biologists interpret these similarities?
10. A species of butterflies from mainland California migrate to a small island off the coast. This is an example of the ..... because a small subset of the population migrated.
11. Approximately one ..... species currently live on earth
12. T or F:Natural Selection and survival of the fittest mean the same thing
13. A random change in a small population's allele frequency is known as
14. Whose theory included "acquired traits" such as a giraffe needing a long neck so they stretch it over time?
15. A group of organisms that can mate with each other to produce offspring is known as a(n) .....
16. Relies on the relative amount of the parent and daughter isotope
17. Protein sequences in one organism that resemble those of another suggest a
18. In an experiment, a population of bacteria is exposed to an antibiotic. Over time, the population becomes resistant to the antibiotic. What evolutionary process does this demonstrate?
19. Magda is a tall, 11 year old drummer. She has a scar on her right cheek. She is good at swimming. Which of her traits did Magda most likely inherit?
20. True or False:Addie's infection is very rare and is becoming less common as medicine improves.
21. Genetic Drift has a greater effect on small populations
22. ..... & ..... are organelles that definitely arose from endosymbiosis.
23. Which statement about the members of a population that live long enough to reproduce is consistent with the theory of evolution by natural selection?
24. An example of high fitness (the ability to survive and reproduce) is
25. The process by which certain traits make it more possible for an organism to survive.
