Incubator
A device that maintains a controlled environment, such as temperature and humidity, to support the development of organisms or cells.
Control Groups
Groups in an experiment designed to prevent false positives and negatives by providing a baseline response for comparison, either showing no effect (negative) or a known effect (positive).
False Positives
An outcome that incorrectly indicates the presence of a condition or effect when it is not actually present.
False Negatives
An outcome that incorrectly indicates the absence of a condition or result when it is actually present.
Negative Controls
A group in an experiment expected to show no response, used to ensure that any observed effect is due to the variable being tested.
Positive Controls
A control group expected to show a response, confirming the experiment's setup and validating the test's effectiveness.
