Explanation:
Scientific research does shows that birds are capable of regenerating their hair cells.
The streams and rivers in the drainage basins were the prairies are converted into farm land are mostly affected by the agriculture and its needs, as well as its consequences.
The agriculture demands water for irrigation, and most of this water comes from the streams and rivers, so that contributes to lowering of the water levels of the streams and rivers.
The agriculture also causes damage to the streams and rivers by polluting them. Namely, the pesticides, herbicides, and fungicides that are used for protection of the plants, partially end up in the low groundwater's, and in general, these waters are connected to the streams and rivers, so the pollutants end up in them, and that affects the biodiversity in them very badly.

Answer:
At the Equator (0° of latitude), the North Star is on the horizon, making an angle of 0°. For any point between the Equator and the North Pole, latitude is obtained simply by measuring the altitude of Polaris: at 30°N the star is 30° above the horizon, at 63°N, it is 63° above the horizon, and so on.
The altitude of Polaris above the horizon at any location on the Earth nearly equals the latitude of that place. This is due to the use of celestial coordinates, an extension of Earth's latitude and longitude onto a celestial sphere, where Polaris is close to the north celestial pole.
To find the altitude of Polaris (the North Star) from your location, you can use your latitude on Earth to get an approximation. The altitude of Polaris above the horizon nearly equals the latitude of the observer. So, for instance, if you are in Washington, DC, which has the coordinates 38° N and 77° W, Polaris would be approximately 38° above the northern horizon.
It's important to note this is related to an imaginary extension of Earth's geography into the sky. Imagine the Earth's latitude and longitude lines expanding onto a celestial sphere, where Polaris is located near the celestial north pole. In this concept, a star's Declination is equivalent to Earth's latitude lines, measured from the celestial equator towards the north or south celestial poles. Polaris is almost +90º, close to the north celestial pole.

Explanation:
Answer: Sewage
Explanation:
The leading cause of contamination in the countries without having water treatment plants is sewage. The sewage disposal is the main waste that needs to be treated.
Sewage has many harmful bacteria growing on it. This can be unhealthy if people are exposed to it. Sometimes the pipes leakage can take place infecting the nearby water bodies.
This can be a very serious issue affecting the freshwater which is used by the people for many domestic and commercial purposes.
