A direct democracy is a system of government in which every citizen votes on every issue. The opposite of this is a representative democracy, in which the citizens vote for representatives who will then vote on issues on behalf of their constituents.

The solid, semi-solid, and liquid land of the lithosphere form layers that are physically and chemically different.
Answer:
The Sun
Explanation:
The sun does not move or rotate and hence cannot retrograde, however the other planets rotate. Some astronomers define retrograde motion as the Westward movement of the planets relative to the sun, based on this definition, all the planets experience retrograde movement. On the other hand, while some astronomers define retrograde motion as the movement that the other planets make when earth passes them while orbiting the sun. Based on this second classification, Mercury and Venus do not retrograde relative to the earth because they move faster than the earth.

short definition:</h2>
<u><em> a species is a population or groups of populations that can potentially interbreed freely within and among themselves.</em></u>

<em><u> Subspecies, are subgroups within a species that have different traits </u></em>
<h2>
long definition</h2>
<em><u>A species is a group of organisms that (in the case of sexually reproducing organisms) can freely interbreed, producing fertile offspring. This definition has its problems, but overall, it encompasses the meaning of the word “species” in biology.</u></em>
<em><u></u></em>
<em><u>A subspecies is, as the name implies, a smaller population within a species that share a particular common trait. Usually a sub species is at least partially genetically isolated from it’s parent species, so that interbreeding is less likely to occur. Most often a sub species is physically separated from the rest of the species, and may have some specific physical differences from the rest of the species. However, they are still able to interbreed with members of the parent population.</u></em>
Earth's atmosphere has a series of layers, each with its own specific traits. Moving upward from ground level, these layers are named the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Hope this helped.
