Class A Fires consist of ordinary combustibles such as wood, paper, trash or anything else that leaves an ash. Water works best to extinguish a Class A fire. Class B Fires are fueled by flammable or combustible liquids, which include oil, gasoline, and other similar materials.
The amygdala is involved in our experience of emotion and in tying emotional meaning to our memories. The hypothalamus regulates a number of homeostatic processes, including the regulation of body temperature, appetite, and blood pressure.

While these regions are important for all, men and women do show differences in the parts of the brain they use to encode emotion.
