Answer:

C. This is an example of VNTRs.

Explanation:

VNTRs are Variable Number Tandem Repeats. These are short sequences of DNA repeated in tandem (that is, the sequences are repeated one next to the other) a certain number of times. Unrelated individuals have a different number of repetitions for a certain region of the DNA, therefore the total length of the fragment is variable among individuals, depending on how many times the short sequence is repeated.

Answer:

The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, it separates the North American from the Eurasian Plate and the African Plate, north and south of the Azores Triple Junction respectively. In the South Atlantic, it separates the African and South American plates. The ridge extends from a junction with the Gakkel Ridge (Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet Triple Junction in the South Atlantic. Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level, for example in Iceland. The ridge has an average spreading rate of about 2.5 centimetres (1 in) per year.[1]
