Answer:
Glaciers act as reservoirs of water that persist through summer. Continual melt from glaciers contributes water to the ecosystem throughout dry months, creating perennial stream habitat and a water source for plants and animals. The cold runoff from glaciers also affects downstream water temperatures. Many aquatic species in mountainous environments require cold water temperatures to survive. Some aquatic insects--fundamental components of the food web--are especially sensitive to stream temperature and cannot survive without the cooling effects of glacial melt water. Such changes in stream habitat may also adversely impact native trout and other keystone salmon species.

The only legitimate basis for the formation of a state is the nation.
Explanation:
The formation of a state can be an easy or a very complicated process. Also, it can be done in a peaceful manner, or through usage of violence and military action. The states have been formed in many different ways over the course of the history. The principle of self-determination though states that the only legitimate basis for the formation of a state is the nation.
- This principle seems good and legit, but in practice has turned out to be very problematic.
- Numerous states have been formed without really having a nation, but more a mixture of different people and cultures stuffed together without even asking them for it.
- There a re lot of nations around the world that do not have states, or rather are not allowed to have states, such as the Basques, Catalans, Kurdish etc.
- Some states have been formed because of the interest of other states, like the example of Kosovo in the Balkans.

Answer:
The stream will flow fastest between 2 and 3.
Explanation:
On this map, we can see two basic elements, one being the contour lines, and the other being the color with which a stream is presented. The contour lines are giving us a good representation of the relief and where it is steeper and where it is less steep. Basically, where the contour lines are closer to each other, we have a steeper relief, and when the contour lines are further away, the relief is less steep.
The water moves under the influence of gravity, so downward. Where the steepness is the greatest, the gravity influences it the most, so it moves faster, while where the steepness is smaller, the gravity influences it less, so it moves slower. On this map, the contour lines are closest to each other between points 2 and 3, meaning it is the steepest part of the relief, and it is the place where the stream flows the fastest.
I would go with D, because acid can be reduced by using it less
