Answer;

-Scientific theory

Once a hypothesis is tested and confirmed, and then tested again and confirmed again by many others, it may provide the basis for, or become a part of, a scientific theory.

Explanation;

A hypothesis is a limited explanation of a phenomenon while a scientific theory is an in-depth explanation of the observed phenomenon.

A hypothesis is constructed before any applicable research has been done. A theory, on the other hand, is supported by evidence: A theory is the result of testing a hypothesis and developing an explanation that is assumed to be true about something. So, when a hypothesis has been verified to be true, it becomes a theory.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
