According to the envelope in Model 1, who is supposed to receive the letter?
matrenka [14]

If you are referring to the model attached, then the answer would be:

<u><em>Jane Doe</em></u>

This model demonstrates how one can categorize something based on certain information from general to specific characteristics. For example, many people have the same names, so how would we know who the person is referring to? Using specific details like the house number, building name or apartment, street and zip code will help narrow down who the letter is addressed to specifically. This is a method they use to organize organisms into specific classifications, based on specific characteristics.
