Answer:
Biogeographic isolation is the separation of organisms of a species through geographical or biological forces.
Explanation:
Answer:A submitter of a premarket notification submission (510(k)) must demonstrate to the Food and Drug Administration (FDA) that the “new device” is “substantially equivalent” (SE) to a legally marketed predicate device. This guidance is intended to help 510(k) submitters demonstrate substantial equivalence. This guidance does not add new regulatory requirements for submitters, it does not change the 510(k) premarket review standard nor does it create extra or new burdens on what has traditionally been submitted in 510(k)s. FDA developed this guidance to improve the predictability, consistency, and transparency of the 510(k) premarket review process. Furthermore, this document is intended to serve as an aid for evaluating the benefit-risk profile of a new device in comparison to the predicate device.
Answer:
A <u> theory </u> may be formed from many related hypotheses that have been tested and support the evidence.
Explanation:
<u>A THEORY -:</u> A theory is a well-established, tested explanation that gives some part of the natural world a unified description. A hypothesis is focused on substantiated knowledge, repeated testing, and a large community of scientists / researchers agree on it.
The aim of a theory is to try to understand phenomena that many researchers have examined extensively and carefully over time. A hypothesis does not prove that the "unified description is correct." However, because the theory is the result of scientifically based research, the theory (as opposed to a single hypothesis) is more likely to be correct. Any hypothesis can (and should) be tested, but many trained scientists must scientifically perform and study the experiments.
