What is biology
100
experimental subjects do not know which treatment (if any) they are recieving.
What is blind experiment design

Term: Life is organized on many levels within individual organisms including atoms, cells, tissues, and organs. And in the world, organisms themselves are organized into many levels: populations, communities, and ecosystems within the biosphere.
What is hierarchical organization
100
the sharing of electrons between two atoms.
What is double bond
100
Any experimental condition applied to the research subjects of an experiment.
What is treatment
200
Term: The irrational belief that actions that are not logically related to a course of events can influence its outcome.
What is superstition
200
Niether the experimental subject, nor the experimenter knows which treatment a subject is recieving.
What is double blind experiment design

is a substance that cannot be broken down chemically into any other substances.
What is an element
200
One atom transfers one or more of its electrons completely to another.
What is ionic bonds
200
A group of subjects who are exposed to a particular treatment.
What is experimental group
300
term: Knowledge that is based on experience and observations that are rational, testable, and repeatable.
What is empirical knowledge
300
individuals make scientific claims that are not supported by trustworthy methodical scientific studies.

What is hydrogen bonds
300
This is the group of subjects who are treated identically to the experimental group, with one exception: they are not exposed to the treatment.
What is control group
400
Term: An explanitory hypothesis for natural phenomena that is exceptionally well supported by the empiracal data.
What is theory
