The Midwest is the biggest agricultural region in the United States, and of the biggest in the world. It is a region that has specialized in the production of several crops that are highly demanded on the market, and are used for multiple different things.
The reason why the Midwest has became an agricultural center is that it has very deep and highly fertile soil. The soil is of such a good quality because naturally this region is a grassland, so the enormous amounts of decaying grasses have created a very good soil suitable for growing numerous types of plants.
Unfortunately, converting the region into an agricultural center has caused lot of environmental problems. The grasslands have mostly been destroyed, and with it the habitat of lot of animals. The extensive usage of pesticides and other chemicals has resulted in pollution of the waters. The mechanization used in the agriculture has become one of the major contributors to the greenhouse gases emissions. Because big portion of the region is semi-arid, or only gets sufficient amounts of rainfall seasonally, the aquifers have been depleted.
It seems that you have missed the necessary options for us to answer this question, but anyway, hope my answer helps. <span>During gas exchange, the cell membrane of a single-celled organism has the same function as the RESPIRATORY SYSTEM. Hope this answers your question.</span>
The answer is - Lighter traffic through rush hours.
The traffic during rush hours is terrible, especially in the big cities, when millions of vehicles are on the streets and everything is blocked and slowed down, which understandably no one likes.
When driving on the side streets though, the traffic in the bigger streets becomes much more bearable and is much faster, so both the drivers that use the side streets benefit from being quicker and evading big traffic, and the ones that drive through the bigger venues have it easier because there's much less traffic and everything is sped up.

Aquatic Biome
The aquatic biome consists of any part of Earth that is covered with water. This includes freshwater and salt water. The aquatic biome can be further divided into freshwater biomes, marine biomes, wetland biomes, coral reef biomes, and estuaries. These subdivisions are based on the salt content of the water, the aquatic plants that live there, and the aquatic animals that thrive there.
Forest Biome
The forest biome is the largest and has a wide variety of plants, trees, animals, insects, and microscopic organisms. The major characteristic of the forest biome is its trees. About 30% of the Earth is considered a part of the forest biome. The forest biome is subdivided by its climate and types of trees present. These subdivisions are: the rainforest biome, temperate biome, chaparral biome, alpine biome, and taiga biome.
Desert Biome
The desert biome has one major, distinguishing characteristic, the fact that it has very little vegetation. The climate is rather extreme depending on its location. The deserts of Africa are extremely hot during the winters and warm throughout the rest of the year. There are also cold deserts such as those in Antarctica. These deserts are extremely cold during the winter and cold during the other seasons.
Tundra Biome
Tundra biomes are the coldest places on Earth. They are similar to a cold desert except they receive less rainfall and contain different animals and plants. Even though the conditions are harsh, the tundra biome does have plant and animal habitats.
Grassland Biome
The grassland biome is made of rolling hills of various grasses. They receive just enough rain to sustain grass but not enough to grow many trees. There are a few trees that will grow in grasslands but sporadic wildfires keep them under control. There are two types of grassland, the savannas and temperate grasslands.
