D
Explanation:
The corn must adapt to the new conditions that it was placed in and will most likely hurt the corn but not make it go extinct.
Answer:
The Niger River will be heavily exploited in the future so that it helps the economies in people in the region.
Explanation:
Most of the big rivers around the world are heavily exploited. They have huge dams built on them for multiple purposes, canals that connect places that don't come out on the rivers, transportation, and travel are well organized and on a high scale. The Niger River though is not that exploited despite having huge potential, but that will change in the near future for sure.
This river goes a long way in the interior of Western Africa and the outskirts of Central Africa. It can support boats, and it is the major factor that supports agriculture. Considering that this part of the world is in a dire situation but develops quickly, the Niger River will be used for sure. Huge dams will be made, and the water will be used for the production of electric power to feed the economies, but also for irrigation as the region is mostly semi-arid, for drinking, and for the industry. In order to boost the economy and help in the development of the large urban areas, canals will be made to the ones that are not located at the river's banks. Transportation through the river's waters will skyrocket as it will be fast, safe, and cheap.
False. Contour lines indicate different levels of elevation. One line might indicate an elevation of 100 feet, and the line next to it an elevation of 200 feet, and so on. When those lines are close together it means that the elevation is rising very quickly from 100 feet to 200 feet, which means a steeper slope. When those lines are farther apart, it means that there's a lot more space between the 100-foot elevation and the 200-foot elevation, which means a more gentle slope.
Answer:
Forests is one of the most important resources for the human beings. we depend upon forest to survive,from the air we breathe to the wood we use is is from forests. beside providing habitats for animals and livelihoods for human, forest also prevents us from different kind of disasters such as landslide, soil erosion etc
Answer:
d). It is easier to make a large reflecting telescope than a large refracting telescope.
f). A reflector can collect more light than a refractor.
Explanation:
A telescope is a device that is used to observe distant objects by the use of lenses and mirrors. It is also used to observe different distant objects by their reflection, absorption, emission or the reflection of the electromagnetic radiations.
Most of the professional telescopes are reflectors because :
1. The reflected telescope is able to receive more of the light when it reflects all the light falling on surface. And it is easier for making a large telescope rather then making large lenses for the refracting telescope. So it is easier to make large reflecting telescope than a large refracting telescope.
2. A reflected telescope receives all the wavelength of the light and it reflects all the light falling on the surfaces where it is refracted telescope that contains lenses cannot absorbs all the light and causes the chromatic aberration.
