It is rich in natural resources.
It relies on hydroelectric power.
Your question asks which statement is not true about North Korea.
Answer: It has a strong agricultural economyThe reason why "It has a strong agricultural economy" would be the correct answer because North Korea DOES NOT have a strong agricultural economy.
The agricultural economy in North Korea is weak. The reason why their agricultural economy is weak is because of the natural disaster that they get and production isn't so high.
North Korea doesn't produce as much agricultural goods as other countries or nations in the world, and it's hard for them to keep a high level production in agriculture.
The practices that they use to farm does not help their agriculture grow, due to the fact that the way they farm is very slow.
They literally have to force people into agriculture, which means that they're suffering in the agricultural world.

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.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.

Final answer:
The Nationalists who came to Taiwan in 1949 were mainly Chiang Kai-Shek and his followers who fled after losing the Chinese civil war against the Communists led by Mao Zedong.
Explanation:
In 1945, after the defeat of Japan in World War II, the Communist leader Mao Zedong emerged victorious in the Chinese civil war and declared the establishment of the People's Republic of China. As a result, the Nationalist leader Chiang Kai-Shek and his followers fled to Taiwan, which was declared the official Republic of China. The United States recognized Chiang's exiled government in Taiwan as the legitimate government for mainland China until the 1970s.
Final answer:
The nationalists who retreated to Taiwan in 1949 were mainly led by Chiang Kai-Shek and comprised the Kuomintang government and its supporters, after losing the Chinese Civil War to the Communist forces of Mao Zedong.
Explanation:
The nationalists who came to Taiwan in 1949 were mainly the remnants of the Kuomintang (KMT) government and its supporters, led by Chiang Kai-Shek. After being defeated by Mao Zedong's Communist forces in the Chinese Civil War, Chiang Kai-shek and the nationalists retreated to Taiwan, which had just been relinquished by Japan following World War II. In Taiwan, they established the Republic of China (ROC), which was recognized by the United Nations and the United States as the legitimate government of all China up until the 1970s and got support from the US during the Cold War period. Despite the geopolitical complexities and changing diplomatic relations, Taiwan's autonomy from mainland China is still under the guarantee of the US.
Select the three main types of map projections.
Interrupted area
Logistical
Mercator
Polar
The three main map projections are the Mercator Projection, used for navigation, the Polar Projection, for the North and South Poles, and the Interrupted Area Projection, for accurately representing landmass areas. ( First, third, and fourth options)
The three main types of map projections are:
Mercator ProjectionPolar (also known as Azimuthal or Planar) ProjectionInterrupted Area (also known as Goode’s Homolosine) ProjectionThe Mercator Projection is well suited for navigation due to its ability to maintain direction, but it distorts size and distance, particularly near the poles. The Polar Projection is used for mapping the North and South Poles and is effective at depicting the area and shape of these regions.
Lastly, the Interrupted Area Projection is used to minimize distortion of area, usually for world maps, where it allows a more accurate representation of the land masses.
Selecting the appropriate map projection depends on the purpose of the map and the geographical area being represented.
Maps aimed at preserving direction for navigational purposes often use the Mercator Projection, where areas like the poles rely on Polar Projections for an accurate depiction of shapes and sizes, and equal-area projections like Interrupted Area are utilized for an accurate representation of landmass areas on a global scale.
William Smith was working as a surveyor in the late eighteenth century. He noticed that certain fossils were found in certain layers of sedimentary or igneous rock, that the same order of strata could be found in areas that were far apart, and these strata contained similar _______.
No Choices to choose from!
William Smith was a British engineer and geologist born in 1769. He is known for having developed the first geological map, based on his observations of the rock layers (strata).
It should be noted that during his studies of these strata, Smith realized that each stratum had certain types of fossil groups, different from the others, as it advanced vertically.
In addition, he observed that in distant places the strata showed the same characteristics and the fossils were always the same at the same level, despite the samples being kilometers far apart from each other.
From there, Smith determined a way to recognize a specific stratum (regardless of its horizontal location) by the fossil remains it contained.
William Smith discovered that specific fossils could be found in particular layers of sedimentary rock, leading to his principle of faunal succession. This principle helped in correlating strata and was essential for the construction of canals by predicting geological formations.
William Smith, working as a surveyor in the late eighteenth century, noticed that certain fossils were found in certain layers of sedimentary or igneous rock, that the same order of strata could be found in areas that were far apart, and these strata contained similar fossils. By utilizing these observations, Smith developed the principle of faunal succession, which asserts that specific types of organisms lived during different time intervals.
Employing his findings, Smith created a detailed geological map of England and Wales, which correlated the strata based on the fossils they contained. This approach not only allowed for the mapping of geological strata and understanding the historical layers of the Earth but also greatly assisted in canal construction by predicting the types of rocks and fossils encountered at different locations, thereby avoiding problematic rock layers.
The concept of faunal succession is a cornerstone in the field of stratigraphy, aiding paleontologists in dating fossils and understanding the evolutionary sequence on Earth. Smith's work laid the foundation for what is now a crucial method in both geology and paleontology.
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

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.

Which of these statements best compares a parent radioactive isotope with the daughter isotope?
Daughter isotope has more stable nucleus than parent isotope.
Daughter isotope has less stable nucleus than parent isotope.
Daughter isotope has more stable electrons than parent isotope.
Daughter isotope has less stable electrons than parent isotope.
Answer:
Daughter isotope has more stable nucleus than parent isotope. ( first choice)
Answer:
Option (1)
Explanation:
The parent radioactive isotopes are those that are comprised of a unstable nucleus, which continuous decay and emits harmful radiations and after consecutive half lives, their original composition reduces to half and so on. It slowly converts into a more stable one, where the nucleus is more stable and emits lesser amount of radiations. These are known as the daughter isotope..
Thus, the daughter isotopes are comprised of more stable nucleus in comparison to the parent isotopes.
Hence, the correct answer is option (1).

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.

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.
