The correct answer is Deletion.
DiGeorge syndrome, more commonly considered as 22q11.2 deletion syndrome. It refers to an ailment resulting when a small segment of chromosome 22 is missing. This deletion leads to poor development of many systems of the body.
The medical issues generally associated with 22q11.2 deletion syndrome involve poor immune system function, heart defects, a cleft palate, delayed development with emotional and behavioral issues, and issues associated with diminished levels of calcium in the blood.
Answer:
a vestigial structure
Explanation:
Vestigial structures are a rudimentary (or even functionless) version of a body part, but they have important functions in a closely correlated or evolutionarily close species, an example of which is the presence of eyes in fish of the genus Astyanax. The existence of these vestigial structures is strong evidence that evolution occurs in organisms, since this structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.
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.
