The correct answer is: b. it doesn’t often reflect reality.
While experimental research has several advantages, including: investigating the effect of one variable on another, and the ability to control and eliminate confounding variables, it also has one major disadvantage. This disadvantage is known as: <em>lack of ecological validity</em>.
Lack of ecological validity means that the findings of research study might not be generalizable to real-life settings, and might only apply to laboratory settings. To avoid the problem of ecological validity, and to increase the validity of an experimental research study, a study should be conducted in natural settings when possible.
D
Methane gas is more potent( roughly by 30 times), as a greenhouse gas than carbon dioxide.
Explanation:
Greenhouse gases in the atmosphere trap infrared radiation (responsible for the transfer of heat) that reflects off of the earth's surface instead of allowing most of this radiation to escape to space. This causes heat to build up in the atmosphere. The more the greenhouse molecules are in the atmosphere the higher this effect is. Global warming is subsequently blamed for climate change around the world.
