The part of the brain which is affected is reasoning center of the new brain. Drinking alcohol also decreases motor function and slow reaction time, this is why when a person is drunk, he/she may not be able to stand or walk a straight line.
Psychoactive drug or psychotropic substance is a chemical substance that acts primarily upon the central nervous system where it alters brain function resulting in temporary changes in perception, mood, consciousness and behavior.
As the population density increases therefore we probably have an increase in birth rate, aslo less space becomes available to individuals and if competition increases that means we probably have an increase in fighting (contest competition) therefore there might be an increase in individuals dying. Therefore I would say the answer is (c) the increase in population density would cancel out the competition. Hope this helps :).
For the first one, electrons travel around the nucleus in fixed energy levels with varying energies.
Second one, protons, neutrons, and electrons have a mass, but electrons have far less mass
Third one, cations and protons
Fourth, not sure.
Rivers are the most important part of the water cycle because
they collect water from precipitation and directly move it back into the ocean.
As this happens, rivers deposit sediments into the ocean that brings about
different formations of lands. They act as drainage systems for other bodies of
water that are found inland.

Aside from transporting water back to the ocean, rivers are
good habitats and food sources for many organisms. Humans are also dependent on rivers. Most early towns were built
around rivers because they accommodated the growing industry of trade and
human civilization as we know it. </span>
