BIOLOGY 181 EXAM 1 STUDY GUIDE AWC DR. SMITH STUDY GUIDE TEST QUESTIONS
WITH ACCURATE SOLUTIONS
Biology
the study of living organisms and their interactions with one another and their
environments
The Scientific Method
includes making observations, forming logical hypotheses, testing them, and form a
conclusion
Scientific Hypothesis
leads to predictions that can be tested by observation or experimentation
We test hypothesis by...
using experiments
Variables
any part of any experiment that can vary or change
Controls
has all parts of the experiments but never varies or changes
,Hypotheses
can never be conclusively proven to be true because we can never test all the alternatives
We either
reject or fail to reject a hypotheses
A hypotheses
must be testable and falsifiable
A theory
is broader in scope than a hypothesis
It is supported by a large body of evidence in comparison
Properties of Life:
1. order,
2. sensitivity or response to stimuli,
3. reproduction,
4.adaptation,
4. growth and development,
6. regulation
, 7. homeostasis,
8. energy processing,
9. evolution
Energy
flows through an ecosystem, generally entering as light and exiting as heat
Chemical elements
are recycled within an ecosystem
cell respiration equation
C6H12O6 + 6O2 ----> 6CO2 + H2O + energy
Photosynthesis equation
C6H12O6 + 6O2 <---- 6CO2 + H2O + energy
Biologist classify life into taxonomic groups
beginning with the most inclusive and ending with the least inclusive
taxonomic groups
