The correct answer is:
<span>A. electron attraction between electron and nucleus = centripetal force of the orbiting electron
In fact, Bohr model depicts the atom as a nucleus surrounded by electrons in circular orbit around it, similar to the planets around the Sun. The centripetal force that keeps the electrons in circular motion around the nucles is provided by the electrostatic force between the electrons and the nucleus, so option A is the correct one.</span>
<span>The first three steps in scientific inquiry are related in that they are all equivalent to being on a fact finding mission. The three steps are to find or develop the question that must be answered, to study all related academic literature on the subject, and then to make a guess as to what the answer is.

Explanation:
PLEASE MARK ME AS BRAINLIEST
Answer:
It regulates the movement of proteins and RNAs into and out of the nucleus
Explanation:
The nuclear pore complex are protein channels connecting the outer membrane of the nucleus to the inner membrane of the nucleus. They securely regulates the almost all of the transport of protein and RNAs into and out of the nucleus.
