Science, the Cell and Molecular Biology
1. Evolutionary processes have resulted in approximately ______million species, of which 1.4 million species have been described.
answer, 4-30.
2. Ideas concerning the theory of organic evolution were published and
supported with convincing evidence by Charles Darwin in ______.
answer, 1859.
3. One source of evidence for evolution is _____. This source is the study of the distribution of organisms around the world and helps explain why animals on different continents are often very different even though their environments are similar. It also explains why fossils of animals now living in Africa occur in South America.
answer, biogeography.
4. Two structures that are similar because of common ancestry are ______.
answer, homologous.
5. Paleontology is a direct source of evidence of evolution because ______.
answer, it is the study of plant or animal remains or impressions that have been encorporated into the earth's crust.
6. When two unrelated animals adapt to similar conditions and
superficial structural similarities result, ______ evolution has occurred.
answer, convergent.
7. Through the year 2000, about 92% of population growth is expected
to occur in ______.
answer, third world countries
8. The one environmental problem that is the root of all other
environmental problems is ______.
answer, over population.
9. The first part of the binomial name of an animal is the _______.
answer, genus.
10. All of the following are presuppositions of science EXCEPT one.
Select the exception.
answer, Science provides absolute knowledge.
11. In an experiment, the ______ serves as a basis for comparing data
derived from the experiment.
answer, control.
12. When scientists talk about a/an _____, they are talking about a
concept that has been supported by data from years of research.
answer, theory
13. A scientist attempts to formulate a reasonable explanation for the
question she is asking. This explanation is called the ______.
answer, hypothesis.
14. In an experiment, the parameter that is being measured to assess the
outcome of the experiment is called the ______.
answer, dependent variable.
15. Which of the following might indicate that an idea being represented
as scientific is actually based on pseudoscience?
answer, The assumptions on which the idea is based are not open to
scientific testing.
16. A fundamental unity in all life involves four common themes: a
common genetic blueprint (in DNA), a fundamental unit of life (the
cell), a common evolutionary origin and shared evolutionary forces, and
a common environment.
answer is True.
17. Animals that have similar DNA molecules are considered
evolutionarily related only if their proteins are substantially different.
answer is False.
18. The wings of a bird and an insect are homologous.
answer is False
19. By the year 2001 the population of the earth will reach
approximately 6.35 million.
answer is True.
20. Bad science is not as dangerous as pseudoscience because the results
of bad science will eventually be refuted. Pseudoscience is not open to
scientific testing, and its conclusions may be difficult to distinguish from
scientific conclusions.
answer is True.
21. Any valid scientific experiment may have more than one
independent variable.
answer is False.
22. Any valid scientific experiment may have more than one dependent
variable.
answer is True.
23. A theory is a hypothesis that has been supported in an experiment.
answer is False
24. In science, the simplest hypothesis that seems consistent with the
evidence is usually the most easily tested.
answer is True.
25. In an experiment, the controlled variables should be the same in both
the experimental and control groups
answer is True
