BIO 101: FINAL EXAM Questions and
Answers 100% Pass (Illinois State
University)
- it is heavily oversimplified
- a scientist cannot explain a hypothesis with one experiment
- science is not at all linear (it is a "sloppy circle")
- this implies that it is an independent effort, which it is not
- it isn't always a planned experiment (serendipity)
- it ignores technology and and societies developing nature - ANS Describe why the scientific
method is inadequate of describing what science is.
- it is not just a theory
- an individual organism cannot just evolve
- evolution does not explain the origin of life
- organisms cannot evolve on purpose if they're smart enough - ANS Explain why the claim
that evolutionary theory is "just a theory" reflects incorrect understanding of what science is.
community analysis and feedback (how science works) - ANS this area consists of feedback
and peer review, replication and/or publication, and discussion/motivation with mutual
colleagues

2. uses energy/has metabolism
3. respond to environmental changes/stimuli
4. regulation/homeostasis
5. growth and development
6. reproduction
7. biological evolution - ANS Identify properties that are shared by all life as we know it
prokaryote - ANS cells do not contain membrane-bound organelles
eukaryote - ANS cells contain membrane-bound organelles and are organized into complex
structures by internal membranes and a cytoskeleton
process where genetic information in a population causes differential reproduction but is
minimized to the better adapted organisms who can sustain life in their environment, those
who do not die off leaving the better heredity to reproduce and leave generations of changing
adaptions to DNA (the strongest and the fittest survive) - ANS explain how natural selection
happens
mutation allows some genes to be modified and can be useful or harmful. mutation is a change
in the DNA sequence causing error in DNA replication and mutagens. - ANS explain the role
of mutation in evolution
- populations become geographically separated
- gene flow is interrupted
- genetic and phenotypic changes accumulate - ANS What occurs in allopatric speciation?
- polyploidy gives rise to new species
- parasite short specificity gives to a new species - ANS What occurs in sympatric speciation?
