One of the disadvantages of experimental research is that
a. it isn’t easily replicated
b. it doesn’t often reflect reality
c. the results aren’t generalizable
d. conditions are not controllable

The Correct answer is option B. It does not often reflect reality.

Explanation:

Experimental research is the process to study that follows scientific research methods and design. This study involves forming a hypothesis, a variable that can be influenced and change by the scientists, it occurs in a controlled atmosphere and conditions and variables that can be compared and measured.

The experimental research may or may not reflect reality due to different reason however these researches can be replicated and are controllable.

Thus, the correct answer is option B. it does not often reflect reality.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
