CORRECT
Biology - ANSWER- The scientific study of life
Atom - ANSWER- Smallest particle of an element that displays the properties of the
element
Cell - ANSWER- Smallest unit that displays the properties of life; always contains
cytoplasm surrounded by a plasma membrane
Molecule - ANSWER- Union of two or more atoms of the same element
Control Group - ANSWER- sample that goes through all the steps of an experiment but
lacks the factor or is not exposed to the factor being tested; a standard agaisnt which results of
an experiment are checked
Placebo - ANSWER- treatment that is an inactive substance, administered as if were a
therapy in an experiment but that has no therapeutic value
Experiment - ANSWER- Artificial situation devised to test a hypothesis
Experimental Variable - ANSWER- value expected to change as a result of an experiment;
represents the factor being tested by the experiment
Homeostasis - ANSWER- Maintenance of normal internal conditions in a cell or an
organism by means of self-regulating mechanisms. Maintaining an internal balance.
Hypothesis - ANSWER- Tentative predictions supported by observations- supposition that
is formulated after making an observation; it can be tested by obtaining more data, often by
experimentation
Conclusion - ANSWER- Statement made following an experiment as to whether the
results support the hypothesis
Theory - ANSWER- An explanation supported by accepted hypothesis- law or explanation
supported by accepted theories, most powerful of the three
, Data - ANSWER- Facts or pieces of information collected through observation and/or
experimentation
Organism - ANSWER- Individual living thing
Science - ANSWER- Development of concepts about the natural world, often by using the
scientific method
Technology - ANSWER- The science or study of the practical or industrial arts
Scientific Method - ANSWER- Process of attaining knowledge by making observations,
testing hypothesis, and coming to conclusions
Double-Blind Study - ANSWER- An experimental procedure in which neither subjects of
the experiment nor the persons administering the experiment know the critical aspects of the
experiment
Peer Review - ANSWER- Not a part of the scientific method but conclusions get published,
another step to look at, results are obtained
Clinical Trial - ANSWER- Trying to figure out if drug is effective or not
Taxonomy - ANSWER- Science of classifying living things. Identifies organisms by assigning
them a specific name and then classifies living things into groups from the largest called a
domain, smallest called a species
Binomial Nomentclature - ANSWER- A method of assigning a two part scientific name to
organisms, genus name first and species second
Probability of Error - ANSWER- always a possibility that the conclusions of an experiment
are in error
Acid - ANSWER- Molecules that raise the hydrogen ion concentration in a solution and
lower its pH numerically
Base - ANSWER- Molecules that lower hydrogen ion concentration in a solution and raise
the pH numerically
Buffer - ANSWER- Substance or group of substances that tend to resist the pH changes of
a solution thus stabilizing its relative acidity and basicity
Atomic Number - ANSWER- Number of protons within the nucleus of an atom
