What kind of noun is doorway?

"Doorway" is a common noun, as it refers to a general object rather than a specific one. It describes a physical space or opening in a wall where a door is typically installed. Common nouns like "doorway" do not require capitalization unless they begin a sentence or are part of a title.


Need fewer meters or fewer centimeters to measure the height of a doorway?

You would need fewer centimeters to measure the height of a doorway compared to meters. Since there are 100 centimeters in a meter, using centimeters would result in a larger numerical value, but you would need fewer total units to represent the height. For example, a doorway height of 2 meters would be 200 centimeters, so using meters requires fewer units.

Is it true that the same mutation could be advantage in some environments but deleterious in others?

No. They are selected for by the environment.Think of all the people in your town. Some are short and some are taller. What if there were a very narrow and low doorway that all had to go through? The shorter ones would do better than the taller ones.In this case, the environment (doorway) selects for genes that are already there but hadn't needed to be used before. Now, shortness is "selected" by the environment. If those going though the doorway were the only ones to get the "other side", their children will also be shorter.You can imagine another shorter doorway and so on, until people on the very last side would be very short compared to those who first started the journey.There were gene variations that were already there and they are selected as they give the person with it a better chance to pass on them.
