BIO 110 MODULE 1 EXAM QUESTIONS AND
ANSWERS
scientific method (hypothesis-based science) - Correct Answers --series of steps that, if
followed, may help a scientist understand an observation
-hypothesis driven
-usually tested with a controlled experiment
-results should be repeatable
cell theory - Correct Answers -1) all living things/life as we know it are made up of cells
2) cells have the ability to reproduce
3)all cells come from preexisting cells (except the first cell)
4) all life as we know it uses DNA as genetic material
theory - Correct Answers -larger scope than hypothesis; widely accepted with a plethora
of supporting evidence that has stood the test of time
hypothesis - Correct Answers -proposed, testable explanation for an observation
controlled experiment - Correct Answers --a test run several times with one variable
changing and, ideally, all other variables staying constant (controlled)
-both a control and a variable, the control used as a baseline measure and the variable
as what is altered, measured, or manipulated in an experiment
discovery science - Correct Answers --the second type of science that provides data
used to describe the natural world
-field studies
-results that have been found from actually having carried out the experiment or
investigation
level 1 - Correct Answers --level of scientific inquiry where a student is given a specific
question
-find info in textbook, notes, or web sources
-purpose: provide foundational terms and facts needed to negotiate the discipline of
biology
level 2 - Correct Answers --level of scientific inquiry where a student is given a
procedure, simulation, or scenario
-draw conclusions from data & observations collected
-purpose: foster confidence in understanding & analyzing quantitative & qualitative
empirical data
, level 3 - Correct Answers --level of scientific inquiry where a student is given a probing
question
-use evidence from various resources to synthesize an answer
-purpose: apply foundational info into integrated scenarios
level 4 - Correct Answers --level of scientific inquiry where a student encounters a
phenomenon or poses a question that is currently theoretical
-design own experiment
-purpose: propose plausible explanation for a phenomenon
concept - Correct Answers --abstract idea
-a mental construct that represents some aspect of the world in a simplified form
HMS Beagle - Correct Answers -the ship that Darwin embarked on a round-the-world
surveying voyage
Galapagos - Correct Answers -group of islands off the coast of South America where
Darwin was struck by the abundant biodiversity
biogeography - Correct Answers --study of the geographic distribution of species
-provides much evidence for the evolution of life on earth
comparative anatomy - Correct Answers --comparisons of the body structures of
modern organisms
-provides insight into evolutionary history
solubility - Correct Answers -The ability of one substance to dissolve in another at a
given temperature and pressure
adhesion - Correct Answers -the ability of water molecules to be attracted to other
charged substances
cohesion - Correct Answers -the ability of water molecules to be attracted to other water
molecules
bioinformatics - Correct Answers --approach in which computational tools are used to
make biological comparisons through examining DNA and protein sequences
Lamarck - Correct Answers -French naturalist struck by the similarities of many of the
animals he studied and was impressed too by the burgeoning fossil record. It led him to
argue that life was not fixed. When environments changed, organisms had to change
their behavior to survive. If they began to use an organ more than they had in the past,
it would increase in its lifetime. If a giraffe stretched its neck for leaves, for example,
make it longer. Its offspring would inherit the longer neck, and continued stretching
would make it longer still over several generations. Meanwhile, organs that organisms
stopped using would shrink.
