BIO 111 (MOLECULAR BIOLOGY) FINAL, BIO 111 EXAM 3
QUESTIONS AND ANSWERS ELABORATIONS!!
inductive reasoning
Answers:form theory based on observations (specific to general)
deductive reasoning
Answers:general to specific
hypothesis
Answers:tentative answer to a well framed question-- cannot be proven only
supported or refuted
scientific theory
Answers:hypothesis that has been repeatedly tested and not yet falsified-- broad,
supported by a large body of evidence
Cell theory (4)
Answers:1. All living organisms are composed of one or more cells.
2. chemical reactions necessary for life take place inside cell
3. all cells arise from pre-existing cells
4. cells contain heredity info (DNA)
decent with modification
Answers:common ancestor-- need for heritable variation for evolution to occur
natural selection
,Answers:individuals in a population will pass their traits and produce offspring
more frequently than others in the population
Hierarchy of Structural Organization
Answers:1. chemical level
2. cellular level
3. tissue level
4. organ level
5. organ system level
6. organismal level
7. population
8. community
9. ecosystem

7 key functions of organisms
Answers:1. respond to external stimuli
2. uptake and process nutrients/energy
3. regulation/homeostasis
4. growth and development
5. repro

7. evolve and adapt
all life shares
Answers:- The same genetic material (DNA, mRNA, tRNA)
, - Nearly universal genetic code (A, C, G,T)
- The same basic process of gene expression (transcription & translation)

4 emergent properties of water
Answers:1. Cohesive behavior
2. Ability to moderate temperature
3. Expansion upon freezing
