BIO 209 EXAM 1 DREXEL FULL REVISION
NOTES WITH PROTEIN STRUCTURE AND
CELLULAR PROCESSES CONCEPTS
◉ control group.
Answer: not exposed to the variable in an experiment
◉ importance of test group & control group.
Answer: they allow researchers to determine whether the variable
in an experiment has an effect
◉ independent variable.
Answer: manipulation performed on the test group
(ex. hours of tutoring)
◉ which axis is the independent variable found on a graph?.
Answer: x-axis
◉ dependent variable.
Answer: effect that is being measured
(ex. test score)
,◉ which axis is the dependent variable found on a graph?.
Answer: y-axis
◉ theory of evolution.
Answer: set of hypotheses that provide a powerful explanation for
both biological observations & the diversity of life
◉ why do we learn that the theory of evolution is the single most
important theory in all of biology?.
Answer: there's lots of evidence from asking/testing good scientific
questions
(ex. anatomy, fossil record, biogeography, molecular biology)
◉ 7 ways living organisms are different from non-living organisms.
Answer: 1. organization - complex organization
2. response - ability to change in response to the environment
3. reproduction - ability to reproduce
4. evolution - capacity to evolve
5. metabolism - chemical rxns that sustain life
6. homeostasis - maintenance of stable internal environment
7. growth - regulated growth/cell division
, ◉ 1st law of thermodynamics.
Answer: energy can neither be created nor destroyed; it can only be
transformed from one form into another
◉ how does the 1st law of thermodynamics apply to living
organisms?.
Answer: - living organisms transform energy from sunlight -->
chemical energy
- cells convert energy by expending it & giving off heat as a by
product
◉ 2nd law of thermodynamics.
Answer: the amount of entropy in the universe is constantly
increasing
◉ entropy.
Answer: amount of disorder in a system
◉ disorder.
Answer: # of states that a system can take on
◉ how does temperature affect entropy?.
