Explanation:
The law of conservation states that the amount of something is preserved even when the shape is altered or even when that thing is deformed.
For example putting the same amount of water in a short big glass and transferring it into a long thin glass doesn't change the amount of water that was initially in the first big short glass and children may not understand this at a certain age until they grow up to understand the law of conservation.
The Mexican or Central Plateau is considered the Heartland of Mexico because it holds the majority of the population there. It has the largest cities, thus attracting tourists. Tourists are more inclined to visit cities or the beautiful (and vast) landscape.
Everyone was aloud to vote and there was no discrimination.
