A(n) ________ is a chamber that isolates the subject from the external environment.

A(n) chamber that isolates the subject from the external environment is commonly referred to as a controlled environment chamber or an isolation chamber. These chambers are designed to maintain a specific set of conditions that can be beneficial for various types of experiments or studies. For example, they are often used in psychological research, where participants may need to be removed from external stimuli to accurately study their responses in a controlled setting. Additionally, these chambers are utilized in scientific research to study the effects of different variables on subjects in a controlled manner, void of external influences such as light, sound, or temperature fluctuations. The use of isolation chambers helps in creating an ideal environment for experiments, allowing researchers to obtain more accurate and reliable results.
