Nectar attracts bees and other pollinators to the flowers and then the pollen gets stuck to the pollinator. Once the pollinator goes to a different flower, the pollen that was originally on the pollinator goes onto the present flower. That is how nectar helps flowers become pollinated

In the currently accepted atomic model, an electron orbits around the nucleus is NOT in a clear, defined path.
Explanation:
According to modern atomic models, like the Bohr theory, it is difficult to know the exact location and path of an electron around the nucleus. This is partly because the mere act of observing the electrons changes its position. This is because the electrons have negligible mass and therefore ‘hitting’ them with any form of radiation for ‘illumination’ changes its position, behavior, and properties. In addition, the movement of electrons is very rapid such that by the time one observes the instantaneous location of an electron, if it was possible, it will have changed its position.
Therefore modern theories, such as VSPER, model atoms based on properties of where an electron will highly likely be found. This is how the shells and subshells of electrons (s, p, d, f) are modeled.

Answer:
B. Some countries have many sources of beryllium, and some have no sources of beryllium.
Explanation:
Beryllium is a very important mineral that is present in many countries. All countries did not have beryllium deposits. Some countries have many sources and deposits of beryllium, and some have no sources of beryllium. There are many deposits of beryllium in different parts of United states of America. Those countries which have no beryllium deposits have cell phones because they purchase cell phones from international market by paying money which can be earned through selling of its goods.
