Answer:
The use of fertilizers
Explanation:
Eutrophication simply implies the increase in nutrient or nutrient enrichment.
Commonly, waterways are connected to other water bodies. When water from farmlands washes fertilizers into them, there is an increase the available nutrient. Overtime, the water can be oversaturated with nutrients and this would lead to eutrophication. We can attribute eutrophication to human activities.

Which of the major continental regions of the United States is best for farming?
The Great Plains is the best for farming.
Question:
Which of the major continental regions of the United States is best for farming?
(a)The Appalachian Mountains
(B) The Sierra Nevada
(C). The Rocky Mountains
(D) The Great Plains
Answer:
The Great Plains regions of the United States is best for farming
Explanation:
The Great plains are the best continental region for farming. Plains are rich in alluvial soils, these soils are formed by deposition of soil by the river over time. These soils are very fertile because they accumulate the runoff minerals from soils and make them nutritionally rich.
The availability of water in plains is more. These plains are covered with grasslands and steppes. It is extended into the Canadian region. The approximate area of these great plains is 13,00,000 square kilometres. States like Kanas, Nebraska, North Dakota and South Dakota are entire of these great plains.

Sequestration is the storage of Industrial[tex]CO_2[/tex] produced by fossil fuels in an underground aquifer or any other structure for long term storage.
Solar and Geothermal energies are called as Green energy, as they do not release any green houses gases in production. They are renewable source of energies. Replacing them with fossil fuels reduces release of [tex]CO_2[/tex]
How was the Homestead Act of 1862 partially responsible for the Dust Bowl?
The homestead act of 1862 was partially responsible for the dust bowl because it gave 160 acres to any adult citizen as long as it was cultivated for 5 years, after 5 years of the 160 acres being cultivated they would give them the land.
Answer:
The Homestead Act of 1862 granted everyone permission to have charge of the government land up to 160 acres each for the purpose of farming. This led young, new and inexperienced farmers to perform futile agricultural activities that resulted in the rise of the Dust Bowl.Explanation:
The Homestead Act of 1862 allowed the individual settlers to carry out agricultural activities on lands up to 160 acres each. The settlers conventionally believed in the idea of 'rain follows the plow'. Tremendous agricultural activity with negligible or no rain at all loosened the soil in the region making it vulnerable to flow with the raging winds in the region causing dust storms to occur. Thus, the southern plains region later started being addressed as the Dust Bowl.Spain Italy and Greece are transitioning to a
Answer:
A service economy
Explanation:
Answer:
Spain, Italy and Greece are transitioning into a service economy due to heavy unemployment and trade deficits.
Explanation:
During the recession in 2008, several countries had faced deep economic crisis including Spain, Greece and Italy. These countries had borrowed money from the European Central Bank (ECB). Various reforms were initiated to make up with the debt crisis but on account of the trade barriers, political uncertainties, tepid growth, stagnant labour productivity, inefficient taxation, poor property rights these processes were of futile exercises. Heavy unemployment in these countries are driving the citizens to work under the service sector. Now these countries are on the verge of Bankruptcy and a debt bubble of one trillion Euros on the horizon. A single currency ‘euro’ for a large ad diversified geographic area makes the monetary policies very challenging to implement and maintain. This has resulted in the poor economic outcomes of the southern European countries like Spain, Italy, Greece, Portuguese.China has used Hong Kong as _____.
an ally in the struggle against Taiwan
a tourist destination
an exchange point for trade with the West
a Special Economic Zone
Hong Kong has been used by China as an exchange point for trade with the West, taking advantage of its status as a capitalist and democratic Special Administrative Region since its return to China in 1997.
China has used Hong Kong primarily as an "exchange point for trade with the West." After the open door policy of China in the 1980s, Hong Kong, a former British colony with a significant port, became a hub of international trade and finance. Post-1997, when sovereignty over Hong Kong was transferred back to China, it remained a capitalist and democratic Special Administrative Region (SAR).
Hong Kong's strategic location and free-market policies have allowed it to become a gateway for trade between China and the rest of the world, including Shenzhen, the Special Economic Zone (SEZ) that benefited significantly from its proximity to Hong Kong's port and trading networks. Moreover, Hong Kong has also been a locus of financial services, attracting global business and banking sectors and serving as a conduit for about one-fourth of China's international trade.

Explanation:
All mass movement occurs on slopes. Without gravity, the material would remain in place and not move. True or false.
Answer:
True
Explanation:
The mass movements are representing movements of large masses of soil, also including rocks, water, biomass in them. These movements though need certain natural conditions so that they can happen. For a mass movement to occur, there has to be a slope, and under the influence of the gravitation, once the conditions are right, there will be movement downward until it reaches a flatter spot. If the terrain is flat, then a mass movement can not occur, as the gravitation is pulling the material down, so it will not be able to move. Also, if the gravitation is lacking, the material will not move anywhere, as without gravitation, there will be no atmosphere, and without atmosphere, there will be no agents to cause the mass movement.
Answer:
True
Explanation:
All the mass wasting process is associated with the principle of the gravitational controls and this principle is essential for understanding the process of the formation of the weathering and the soil erosion process and flowage of the material down the slopes of the hills or the mountain etc.As the steeper slopes are more likely to have the mass wasting and as compared to the gentle and more flat slopes. The rock falls, and the slumps and the debris flows are all examples of mass wasting. Thus all the falls, slides, creeps and flows occur due to the gravity of the earth and fluidity of the materials.Josh bought 800 plastic whistles to give away to the kids at a street fair. Some of the whistles were small and cost $0.50. The larger whistles cost $0.75. In total, he spent $550 on the whistles. How many of the small whistles did he buy?
Answer:
200 small whistles.
Explanation:
[tex]0.5s+0.75l=550\\s+l=800[/tex]
This is a system of equations for this problem, where s refers to small whistles and l refers to large whistles. The first equation represents the added costs of the whistles equaling the total cost, and the second equation represents the added amount of whistles purchased equaling the total amount of whistles.
To solve, simply isolate the second equation for l.
[tex]s+l=800\\l=800-s[/tex]
Next, substitute your new value of l into the first equation and simply.
[tex]0.5s+0.75(800-s)=550\\0.5s+600-0.75s=550\\-0.25s+600=550\\-0.25s=-50\\s=200[/tex]
Once complete, you'll have solved for your s value (200), which is your answer.
Final answer:
To determine the number of small whistles Josh bought, a system of linear equations is set up and solved, using the provided information about costs and total numbers.
Explanation:
The question involves solving a system of linear equations to determine the number of small and large whistles bought by Josh. Given that the small whistles cost $0.50 each and the large whistles cost $0.75 each, and Josh has bought a total of 800 whistles spending $550, we can set up two equations to represent this situation:
Let x be the number of small whistles and y be the number of large whistles.
Equation for the number of whistles: x + y = 800
Equation for the total cost: 0.50x + 0.75y = 550
By solving this system of equations, we can find the value of x, which represents the number of small whistles Josh bought.

One thing that is causing increased pressures on the Ogallala Aquifer is the tendency of farmers to plant crops that require even more water than usual. Which of the following are "thirsty" crops that farmers have started planting? Select one: a. Cashews and Pecans b. Almonds and Grapes c. Grapes and Cranberries d. Cashews and Almonds
Answer:
d. Cashews and Almonds
Explanation:
The Ogallala Aquifer is an enormous aquifer located in the southwestern part of the United States. Despite having enormous amount of water, this aquifer is facing serious problems and its water levels are constantly going down. The main reason for this is the agriculture, or rather the type of plants that are planted in the region. The region is relatively dry, so instead of choosing plants that are suitable to the dry conditions, the farmers opted for the plants that are highly profitable, but demand lot of water. Some of these plants are the almonds and cashews, both of which demand lot of water, and on top of it, being grown in much warmer and drier conditions, means that they require even more water than usual.
Farmers planting water-intensive crops like almonds and grapes are contributing to the depletion of the Ogallala Aquifer, with the current usage rate being unsustainable as the aquifer recharges much slower than it is depleted. (option b)
One thing that is causing increased pressure on the Ogallala Aquifer is the tendency of farmers to plant crops that require even more water than usual.
Among the water-intensive crops that are contributing to the depletion of the Ogallala Aquifer are almonds and grapes.
These "thirsty" crops have been increasingly planted by farmers, but these choices are unsustainable considering the current rate of aquifer depletion, as the aquifer's water is being used up much faster than it can recharge.
Pivot to crops that require less water, such as milo, might be necessary to preserve the Ogallala Aquifer for continued agricultural use and municipal water supplies on the Great Plains.
what are some advantages to an oligarchic form of government
Oligarchy allows citizens to have the time to focus on their daily lives, more creative technologies to be created.
This is because oligarchy gives power to a group of experts which makes the government function properly .
Hope this helps!
Answer:
In an oligarchy the power is in the hands of a small group of people who belong to a privileged class. In ancient times it was the ruling caste that possessed the power monopoly: a hereditary social grouping that is separated from the rest of society by religion, kinship, economic status, prestige and sometimes even language. Such elites tend to exercise power in the interest of their own caste.
In an oligarchic form of government, the validity of the laws is based on the discretion (group willingness) of this closed elite. It is one of the five forms of state described by Plato, who identifies the oligarchy as the "bad" variant of aristocracy because the oligarchy only aims at favoring its own class.
Given this definition and the way in which they favor their social group, the oligarchies have few positive attributes regarding society in general and the state as a common whole. However, an advantage that these governments may have lies in the continuity of policies that, although they are aimed at favoring the elite, provide security to the remaining nations regarding their relations with the government, as well as with respect to the measures they will carry out. In this way, they provide stability and, if their policies are favorable to free trade, they can encourage foreign investments.
Chemical rocks are formed by what grow out of solution?
Answer:
precipitate
Explanation:
Chemical sedimentary rocks are rocks that are formed as a result of precipiation of minerals from solutions. The solutions are usually derived from dissolved loads during erosion. When they get to basins where they settle and more materials are dissolved, the solutions becomes supersaturated. This implies that the solvent contains more than enough solute it can normally dissolve. In this regard, the solution would begin to crystallize and precipitates will form from the solution.
Examples of such rocks are gypsum, limestone, anhydrite, sylvite
Answer:crystals

Isotopic dating relies on a process called _______, where heavier radioisotopes transform into lighter elements.
No choices to choose from!
Radioactive decay is a spontaneous process in which the nucleus of an atom disintegrates, giving way to the emission of radiation and the appearance of a new nucleus, releasing energy in the process.
This process is widely used in radioactive geological dating (also called isotopic dating or radioisotope dating) in which radioactive impurities were selectively incorporated when the fossil materials were formed.
Therefore:
Isotopic dating relies on a process called radioactive decay
What was a negative consequence of industrial capitalism?
Answer:
•working poor
•factor workers
•lower class
Answer:
Some people criticize certain aspects of capitalism that, according to these critics, can be solved without abolishing capitalism.
The existence of an unequal distribution of wealth and power is criticized. Many Social Democrats want to reduce income differences through, for example, progressive income tax. According to these critics, very large income inequality is undesirable because of the negative consequences for social cohesion. "Wage slavery" is generated in this way, in which employees, although they are paid, have very low salaries, which only allow them to subsist to continue working and generating wealth for employers.
Companies concentrate on profitability, which according to critics leads to unsustainable behavior. For example, it is more profitable to have products produced in countries with low wages, with these being sold in richer countries. This requires a lot of transport and therefore more emissions, which could be prevented by producing goods in the vicinity where they are consumed.

Many species of this group perform the important role of making an essential nutrient available to other organisms and are therefore called .
Answer:
producers (autotrphs)
Explanation:
The autotrpophs, also known as producers, are the organisms that are the basis of all ecosystems. The reason for this is that they are the ones that are capable of [producing their own food. By doing so, they are the ones that produce energy, energy that is transferred through the trophic levels above them. This means that the producers provide the nutrition for all the other organisms, be it the primary or secondary consumers, and if they are eliminated, then the ecosystems will crumble and fall apart very quickly.
Final answer:
Many species that perform the important role of making an essential nutrient available to other organisms within an ecosystem are typically bacteria and fungi, known as decomposers or detritivores. These organisms are critical in nutrient cycling by breaking down dead organic matter and releasing nutrients back into the ecosystem for use by plants and other organisms. Specifically, they are integral to the cycling of nutrients like nitrogen and carbon, which are essential for the growth of plants and the overall health of the ecosystem.
Explanation:
In an ecosystem, plants play a pivotal role as primary producers, initiating food chains and encompassing organisms such as Allotropa, Matsutake, and tanoaks, which are primary producers and photosynthetic autotrophs. Bacteria and fungi, on the other hand, help in degrading organic matter, which complements the plants' role in nutrient cycling. For instance, fungi form symbiotic relationships with plants like the Matsutake mushroom, which forms mycorrhizal associations with trees, aiding in nutrient and water absorption.
These relationships between different species often result in coevolution, where two or more species reciprocally affect each other's evolution. This is seen in mutualistic symbioses in the lab, but can also be observed in parasitic symbioses, where both the parasite and the host may evolve traits in response to each other. Vitamins are also pivotal in nutrition; while some bacteria and archaea synthesize their own vitamins, others, especially multicellular organisms, rely on dietary intake to fulfill their requirements. Understanding these complex interactions and the roles of different organisms underpins the study of ecology and botany.

how does flood water stay in one area because last time I checked nothing was holding the water in, and if the earth is round it should just spread out shouldn't it?
It could be that since there are "bumps" all around our surface. These "bumps" could potentially act like walls, keeping the water in one place.
Reason why flood water stagnant in same area:
A flood occurs when there is a excessive rain, breakage of dam, heavy climate change and speedy melting of snow or ice. Usually the flood water can be constrained in a particular place that can be in a crater surface. This is caused by improper drought management and and natural hazards.
Though the infrastructure development keep on improving, the drought management system remains the same. So, the flood water stays in one area even though the earth is round. The government should take steps to ensure the security of citizens by taking care of the flood water development.
It can be spread out or saved by rain water management system. If the flood water stays in one area that is dangerous and make you ill-protected to infectious diseases, chemical hazards, and injuries.

The population growth rate of the entire world had reached a little above 2% a year back then.Which of the following is true about ecosystems?
Ecosystems are communities that include both living organisms and non-living elements. They are characterized by energy flow through food chains and nutrient cycles, with energy being lost at each trophic level. The proper functioning of ecosystems is vital to the health of the biosphere, which can be adversely affected by human activities.
Explanation:Understanding Ecosystems
An ecosystem is a dynamic complex of plant, animal, fungal, and microorganism communities and the nonliving environment, interacting as a functional unit. Ecosystems are characterized by the flow of energy through food chains, and they have various trophic levels which represent each step in a food chain. Primary producers, usually plants and phytoplankton, are at the first level, followed by herbivores at the second, carnivores at the third, and so on. The energy transfer between each trophic level is inefficient, with a significant amount of energy lost at each stage, primarily as heat. Moreover, ecosystems also have biotic and abiotic components, where biotic refers to living things, and abiotic refers to non-living things like water, sunlight, and minerals.
Ecosystems can range from local aspects like a tide pool to major regional systems like the Amazon Rainforest. The elements and water within ecosystems are constantly recycled, contributing to the ecosystem's functionality, while energy, primarily from sunlight, is required from external sources. A species' niche includes its role within the ecosystem and is defined by how it gets its energy and nutrients and how it interacts with other living and nonliving aspects of the ecosystem.
It's important to recognize that human activities, including pollution and contributing to climate change, can negatively impact these delicate systems. Understanding the roles of different organisms within their ecosystems and the cycles that govern the flow of energy and matter is critical to protecting and preserving our natural habitats.
