ANSWERS 100% CORRECT
Observation, Problems and Questions, Hypothesis, Observations and
Experimentation, Data collection and analysis, Conclusions, Theories -
ANSWERparts of the scientific method
Observation - ANSWER"My Roommate said Biology 200 students smile during lab"
Problems and Questions - ANSWER"What is the most exciting class at Minnesota
State Mankato?"
Homeostasis - ANSWERall living things maintain constant internal conditions
Reproduction growth and development - ANSWERall living things reproduce using
DNA
Evolution - ANSWERall living organisms change genetically as a population over
multiple generation
DNA - ANSWERa self-replicating material present in nearly all living organisms as
the main constituent of chromosomes
classification - ANSWERbased on observable characteristics such as structures,
mode of development, genetics and sometimes behaviors.
photosynthetic - ANSWERtype of autotroph that makes its own food using energy
from sunlight
external digestion - ANSWERtype of heterotrophic process in which one organism
dissolves another organism externally and then brings the dissolved materials inside
ingestion - ANSWERtype of hetertrophic process in which one organism takes body
parts of or wastes from another organism into its digestive tract for internal break
down
flagella - ANSWERtail like structure
nonmotile - ANSWERno motion
cilia - ANSWERmany hair like structures
contractile fibrils - ANSWERwithin organism, get smaller to create movement
ameboid (speudopodia) - ANSWERfake "foot" that oozes outward
, Multicellular - ANSWERorganisms that have cells with specialized cell functions
Hypothesis - ANSWER"Bio 100 is the most exciting class at Minnesota State
Mankato"
Observations and Experiments - ANSWER"All exiting Minnesota State Mankato
seniors were given a survey asking them what class at Mankato the most exciting"
Questioning - ANSWEROccurs when you identify and state a problem or ask a
question. Needs to be understandable, doable, and testable, falisifiable.
Good Characteristics of Hypotheses - ANSWERAn educated guess or a possible
explanation for an observed set of facts that lends itself to being tested. Must be
testable through experiments, must be very specific, and can be written in several
formats.
Scientific Theory - ANSWERA well-substantiated explanation of some aspect of the
natural world, based on a body of facts that have been repeatedly confirmed through
observation and experiment.
Observation - ANSWERThe process of gathering information throughout the senses.
Subject Expectation - ANSWERForm of reactivity that occurs in scientific
experiments when a research subject expects a given result and therefore
unconsciously affects the outcome
Observer Bias - ANSWEROccurs when the observers know the goals of the study or
the hypotheses and allow this knowledge to influence their observations during the
study.
Double Blind Experiment - ANSWERNeither the participants nor the researchers
know which participants belong to the control group, nor the test group.
Random Assignment - ANSWERPlacement is an experimental technique for
assigning subjects to different treatments
Controlled Variable - ANSWERThe quantities that a scientist wants to remain
constant.
Independent Variables - ANSWERThe values you are manipulating and have control
over
Dependent Variable - ANSWERWhat you measure in the experiment and what is
affected during the experiment.
Sample Size - ANSWERThe number of observations in an assignment.
Generalization - ANSWERA general statement obtained by inference.
