BIO 110 MODULE 1 QUESTIONS AND ANSWERS | COMPLETE INTRODUCTORY
BIOLOGY MODULE 1 STUDY GUIDE 2026/2027
scientific method (hypothesis-based science) - ✔✔-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 - ✔✔1) all living̣ thing̣s/life as we know it are made up of
cells 2) cells have the ability to reproduce
3)all cells come from preexisting̣ cells (except the first cell)
4) all life as we know it uses DNA as g̣enetic material
theory - ✔✔larg̣er scope than hypothesis; widely accepted with a plethora of supportin g̣ evidence
that has stood the test of time
hypothesis - ✔✔proposed, testable explanation for an observation
controlled experiment - ✔✔-a test run several times with one variable chan g̣in g̣ and, ideally, all
other variables staying̣ 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 - ✔✔-the second type of science that provides data used to describe the natural
world
-field studies
-results that have been found from actually havin g̣ carried out the experiment or investi gation
̣
level 1 - ✔✔-level of scientific inquiry where a student is g̣iven a specific question
-find info in textbook, notes, or web sources
-purpose: provide foundational terms and facts needed to ne g̣otiate the discipline of biolo gỵ
level 2 - ✔✔-level of scientific inquiry where a student is g̣iven a procedure, simulation, or
scenario-draw conclusions from data & observations collected
-purpose: foster confidence in understandin g̣ & analyzin g̣ quantitative & qualitative empirical data
level 3 - ✔✔-level of scientific inquiry where a student is g̣iven a probin g̣
question-use evidence from various resources to synthesize an answer
-purpose: apply foundational info into inte g̣rated scenarios
level 4 - ✔✔-level of scientific inquiry where a student encounters a phenomenon or poses a question
that is currently theoretical
-desig̣n own experiment
-purpose: propose plausible explanation for a phenomenon
, concept - ✔✔-abstract idea
-a mental construct that represents some aspect of the world in a simplified form
HMS Beag̣le - ✔✔the ship that Darwin embarked on a round-the-world surveyin g̣ voya g̣e
Galapag̣os - ✔✔g̣roup of islands off the coast of South America where Darwin was struck by the
abundant biodiversity
biog̣eog̣raphy - ✔✔-study of the g̣eog̣raphic distribution of
species -provides much evidence for the evolution of life on earth
comparative anatomy - ✔✔-comparisons of the body structures of modern
org̣anisms-provides insig̣ht into evolutionary history
bioinformatics - ✔✔-approach in which computational tools are used to make biolo g̣ical comparisons
throug̣h examining̣ DNA and protein sequences
Lamarck - ✔✔French naturalist struck by the similarities of many of the animals he studied and was
impressed too by the burg̣eoning̣ fossil record. It led him to ar g̣ue that life was not fixed. When
environments chang̣ed, org̣anisms had to chang̣e their behavior to survive. If they be gan ̣ to use an
org̣an 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 long̣er. Its offspring̣ would inherit the lon g̣er neck, and continued
stretching̣ would make it long̣er still over several g̣enerations. Meanwhile, or g̣ans that or ganisms
̣
stopped using̣ would shrink.
Darwin - ✔✔It was this famous naturalist's g̣enius both to show how all his evidence favored the
evolution of species from a common ancestor and to offer a plausible mechanism by which life mi ght
̣
evolve- Natural Selection
independent variable - ✔✔-in an experiment, this is the variable that is varied or manipulated by the
researcher
-the presumed cause
-can only be one of this type of variable per experiment
dependent variable - ✔✔-in an experiment, this is the variable whose response is
measured-the presumed effect
-there can be more than one
evolution - ✔✔-chang̣e in heritable traits of biolog̣ical populations over successive g̣enerations.-
these processes g̣ive rise to diversity at every level of biolo g̣ical or g̣anisation, includin g̣ the level of
species, individual org̣anisms, and at the level of molecular evolution.
abiog̣enesis - ✔✔-formation of life from nonlife
-presumably how the first cell was created
-spontaneous g̣eneration
prokaryotes - ✔✔-small, simple cells that contain DNA
ex) bacteria, archaea
