What would happen to a cell if, during the splitting of chromosomes, two did not separate- and one cell got a double set and the
cestrela7 [59]

Answer:

Explanation:

The correct pairing of the homologous chromosomes and their correct segregation (a chromosome for each daughter cell) are key to the proper development of the new cells, and specially of the new individual if we are talking about the early stages of embryogenesis. If there is an error during the splitting of chromosomes, and one cell gets a double set and the other misses a chromosome, numerical chromosomal abnormalities occur. These numerical abnormalities can happen on autosomes or sexual chromosomes, and common examples are as Down Syndrome (trisomy 21), Patau Syndrome (trisomy 13), Turner Syndrome (45,X) and others. The number of the trisomy indicates the chromosome pair that suffered the adding or the subtraction of its chromosome.

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.
