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.

Answer:The Green Revolution resulted in increased production of food grains (especially wheat and rice) and was in large part due to the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century with Borlaug's work.
Explanation:
The meeting of the First Continental Congress was the first organized act of resistance in the colonies in response to the passage of the Intolerable Acts.
<u>Explanation</u>:
Intolerable Acts was passed in the year 1774 during U.S. colonial history. Some of the Intolerable Acts are
i) Boston Port Bill
ii) Massachusetts Government Act
iii) Administration of Justice Act
iv) Quartering Act
The Boston Port Act was passed in 1774 against the Boston Tea Party. Colonists responded to the Intolerable Acts with unity, and made First Continental Congress to discuss and negotiate the unified approach to the British.
The difference was that serfs were required to work for their lord and give him food for exchange of protection when war times appeared. Peasants, on the other hand, had no obligation to do so, they were just people who were agricultural workers and were growing crops.
