Bio 204 final Exam
1. What are the characteristics of life?: -reproduction (sexual or asexual)
-Growth and development (start as a single cell and grow/develop into multicellular organisms)
-Energy use (brought in, converted to useful forms and expelled)
-cells (unicellular and multicellular)
-order (biosphere, ecosystem, community, population, organism) (organism, organ system, organ, tissue, cell, or-
ganelle, molecule, atom)
-Response to environment (homeostasis)\
-Evolution
2. Define biology?: -Scientific study of life
3. What can we do when science is defined and used properly?: use facts and hypotheses
to formulate theories about our lives and the world around us
4. what is a fact?: observation that has been repeatedly confirmed
5. What is a hypothesis?: tentative statement about a natural phenomenon that can be tested; support or
refuted
6. What is a theory?: Highly probable, well-tested and substantiated explanation of a natural phenomenon
,based on a large collection of observations and experiments (ability to consistently predict new phenomena)
7. What is a law/principle?: description of observed phenomena; based on empirical data and can typically
be defined mathematically
8. What are the attributes of science?: -Testable (hypothesis)
-Repeatable
-Falsifiable
9. What is the hypothetico-deductive?: -Observation
-Question
-Hypothesis
-Empirical test
-Conclusion
10. Science is not...?: -solution to all problems and questions
-ignorant of rules
-road to the truth
-out to prove anything
-100% certain
-final answer
,-infallible
-unbiased
-always used properly
11. What is evolution?: -Descent with modification
-Descent (from generation to generation)
-Modification (change)
12. What does genetics explain?: how traits are passed from one individual to another (inheritance of
biological characteristics)
13. What are chromosomes?: single strand of DNA with thousands of genes
14. What is a gene?: Information that codes for inherited traits (on DNA)
15. What is a locus?: Position of the gene on the chromosome
16. What is a genome?: -Collection of genetic information (DNA) in a cell
-Single strand of DNA containing genetic material, which is passed from parent to offspring
17. What did Walter Sutton do?: -Studied grasshoppers
-recognized chromosomes come in pairs
, -Hypothesized one set maternal and one paternal
18. What did Theodor Boveri do?: -Studied sea urchins
-noticed that all chromosomes must be present for proper embryonic development
19. What is the chromosome theory of inheritance?: Chromosomes are the carriers of genetic
material
20. How many chromosomes does a human have?: -46
-2 sets of 23 chromosomes from each parent
21. What are gametes?: -sex cells
-1 set of chromosomes (1n=haploid)
22. What are somatic cells?: -all cells that are not gametes
-2 sets of chromosomes (2n=diploid)
23. What do we call a single strand of DNA containing genetic material, and
which is passed from parent to offspring?: chromosome
24. What does DNA do?: -directs cellular functions (protein synthesis)
