BIO 111 EXAM 1 TAMU TEST QUESTIONS WITH ACCURATE SOLUTIONS
Natural Science
· the field of science related to the physical world and its phenomena and processes.
Physical Science
astronomy, chemistry, physics
Life Science
Biology
Basic Science
Science done to gain knowledge, regardless of the application. "knowledge for knowledge"
Applied Science
Science applied to the real world. The problem is defined by the researcher
Inductive Reasoning
Describes through careful observation and analysis of data. Scientist derive
generalizations based on a large number of observations.
,Deductive reasoning
ask specific questions usually involving proposing and testing hypothetical explanations
aka hypothesis.
Hypothesis
must be testable, falsifiable and include a control group.
Scientific Method
o Make observations
o Develop a hypothesis
o Design an experiment
o Collect data
o Analyze data; do the results support the hypothesis
o Refine and repeat the experiment if necessary
Communicate your results
independent variable
The experimental factor that is manipulated; the variable whose effect is being studied.
dependent variable
represents the output or outcome resulting from the altering of the independent variable.
, Scientific Theory
hypothesis that has not been disproven after many years of rigorous testing
cell theory
o All living organisms are made of one or more cells besides viruses (they aren't REALLY
alive)
o Chemical reactions that are necessary for life take place within cells
o All cells arise from pre-existing cells, they don't just appear randomly
o Cells contain hereditary information in the form of DNA
emergent properties
· life's fundamental characteristic is having a high degree of order
o Biological organization is based on a hierarchy of structural levels; the lowest is atoms
that build to complex biological molecules, molecules arrange to create structures and
organelles which make cells
Key Functions of Life
o Order
o Sensitivity or response to stimuli
o Reproduction
o Growth and development
o Regulation
