One positive effect of devolution is that it helps maintain a cohesive state. This means that it helps the state remained unified.
Middle America refers to the states to the south of the US and specifically Mexico, the states of Central America and Islands near Central America. Venezuela does not belong to those states; It is part of South America and it is quite far from the other areas, relative to the distance between them.
Elevation, there is a lot less gravitational pull the higher up you go.
Weight- weight is actually the amount of pressure gravity has on the object. The greater the gravitational pull, the heavier the object will be.
Distance- the farther away something is, the less gravitational pull it might have on another object.
Size- the bigger the object, the greater the gravitational pull. You jump higher on the moon than you do on Earth because the earth is larger and therefore has a greater pull on objects to its surface
Hope this helps
By seeing how long or short the days are. and where sun is located

Option D plants cells are affected when water sources are less. Therefore I believe that option B is the one I would go with.
