how might testing small-scale building models or their components be helpful in testing improvements and changes to the building design

& Explanation:

small scaled building models are very rare to make/build nowadays.

due to advance technology it is more wiser and more convenient to use 3d programs like revit in creating building model to scale.

so It is always a good idea to make models of your ideas, before deciding on the final design.

This will help you determine whether your idea is going to work or needs modifying. A model allows you to test your solution quickly and cheaply.

Reworking a massive building takes years, millions of pounds, and meticulous planning and project management.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
