set with Questions and correct/verified
Answers
Microscope - ANSW-A device used to see tiny organisms, used for research and counting.
Spectrophotometer - ANSW-A device that passes light through a substance in order to assess the
absorption and transmittance.
Absorbance - ANSW-Measurement of the amount of light captured by the dissolved or suspended
material.
Transmittance - ANSW-The fraction of incident light at a specified wavelength that passes through a
sample.
investigated - ANSW-The questions that are asked in science should be able to be _______.
Hypothesis - ANSW-A prediction for why something is the way that it is, or why something occurs.
Should be testable and falsifiable (able to be disproved).
Theory - ANSW-A _____ is a well confirmed ANSWer/prediction/explanation of nature that is supported
by large body of evidence.
Observation - ANSW-The act of watching something in order to gain information. It is completed before
making a hypothesis.
Experiment - ANSW-An orderly procedure carried out with the goal of verifying, refuting or establishing
validity of a hypothesis.
Control - ANSW-A group that is separated from the rest of the experiment where the variable being
tested cannot effect it.
Variable - ANSW-Any factor that can be controlled, changed or measured in an experiment.
Life - ANSW-_____ distinguishes organisms from inorganic objects and dead organisms, being manifested
by growth through metabolism, reproduction and the power of adaptation.
Life - ANSW-The following are characteristics for what?
-organized
-require energy
-grow and develop
-respond to environment
-can reproduce
-adapt to environment
, AMCTOOPCEB - ANSW-Levels of Organization in Living Things (acronym)
Repeatability - ANSW-_____ is required in order for scientists to accept an observation or the results of
an experiment; helps with validity of said experiment.
Sampling - ANSW-Making tests or observations on a subset of the entire population of experimental
objects.
variable - ANSW-A good experiment should have only one ________.
Evolution - ANSW-_________ is the change in the inherited characteristics of biological characteristics of
populations over successive generations.
Natural Selection - ANSW-_____ _______ is the gradual process by which biological traits become either
more or less common in a population.
Heritable Traits - ANSW-Natural selection affects a population through what?
Natural Selection - ANSW-The following are necessary for what to occur?
1. Heritable variations exists in a population
2. The number of offspring that can be produced is greater than the number that are produced
3. Not all individuals in a population are equally successful at survival and reproduction; this differential
success is at least partially due to different inherited traits in the different individuals
T - ANSW-True or false: environmental factors can be agents of natural selection
Relative Fitness - ANSW-Measurement for how well individuals with certain traits survive and reproduce
in a particular environment.
Cumulative - ANSW-Is evolution better represented by the single-step or cumulative model?
Biodiversity - ANSW-_____ is due to evolution and natural selection. Without it we would all be the
same.
Phylogeny - ANSW-The hypothesized evolutionary relationships between species.
Taxonomy - ANSW-The classification of organisms into groups (identifying and naming).
Cladistics - ANSW-A method of classification of organisms according to the proportion of measurable
characteristics that they have in common.
DKPCOFGS - ANSW-Hierarchy of classification of life (acronym)
Bacteria Archea Eukarya - ANSW-Three Domain Classification system
Homologous - ANSW-"of the same" ... sharing characteristics of structure
Analogous - ANSW-"different" ... not being the same at all
Observation Hypothesis Experiment Conclusion - ANSW-What is the proper order for the steps of a
scientific study?
