Answer:
Hypothalamus
Explanation:
Most of these behaviors are related to a person's hormones. Hormones are influenced by the Hypothalamus. This is a tiny part at the base of the brain close to the <u><em>pituitary gland</em></u>. The hypothalamus is in charge of releasing hormones, regulating body temperatures, controlling appetite, sexual behavior, and regulating emotional responses. Which falls in perfectly with all the behaviors in the question.
The Great Plains are located on the North American continent, in the countries of the United States and Canada. In the United States, the Great Plains contain parts of 10 states: Montana, North Dakota, South Dakota, Wyoming , Nebraska, Kansas, Colorado, Oklahoma, Texas, and New Mexico.
When burning, Yes.
A normal fire in a steel-frame building can soften the structure to the point of collapse.
Building laws / regulations require that all the structural steelwork is either covered in a protective coating (such as intumescent paint) or boxed in with fire-resistant plaster, so the fire can be extinguished before the building is weakened - or at least give people time to get out.
If that coating or plaster is damaged by impact or an explosion, the steel is exposed and the building can collapse relatively quickly.
(The common intumescent coatings just look like paint until exposed to fire, so the steelwork may appear to have no particular protection - but it always does).

See the images below - small buildings with steel-frame roofs after fires; you can see the amount of "sagging" and distortion on structures that have no particularly high loads.
These have burned long enough to destroy any protection, or they did not have any as the structure does not support occupied space.
