Biology - ANS ✔✔Scenic Study Of life
7 properties of life . - ANS ✔✔Reproduction, Growth and development Energy use, order, Cell,
Response to the environment, Evaluation
Something does not display all properties of life. Is a virus alive? - ANS ✔✔A virus is NOT ALIVE
Biological Organization LARGEST TO SMALLEST - ANS ✔✔biosphere, ecosystem, community,
population, organism, organ, tissue, cell,molecule, atom
What is the scientific method? - ANS ✔✔A serious of steps, that if followed may provide insight
about the natural world
scentific method in order - ANS ✔✔Observation
Question
Hypothesis
Experiment
Results
Conclusion
Hypothesis - ANS ✔✔a proposed explanation for an observation
Theory - ANS ✔✔A well sub-stained explanation that is much broader in scope then a
hypothesis

some info about the experiment is withheld from the participants.
Double blind: An experiment in which neither the participant nor the experimenter knows
which group is which
Placebo : A medically ineffective treatment that allows the placebo group to serve as a control
for the real drug

- original material presented for the firstvil time by the person who performed the research
Secondary Source - A description OR Reveiw of primary Source , often Containg commentary
What does a line graph, bar graph, and pie Chart Show ? - ANS ✔✔Line graph - Often used to
display data that changes continuously, made by plotting many Individual pieces of data &
Connecting dots.
