What are some leading hypotheses (informed theories) about how our species emerged? How are humans different?
Answer:
"Out of Africa" model of pattern of human evolution, clinical variation model of Center and Edge, and the Assimilation Model.
Explanation:
There are many hypotheses and the scientific models that provide the alternative explanation to more of the widely accepted theorems of the out of Africa models and they describe the multiplication patterns of the human species and the archaic human forms such as those of the Neanderthals. The Center and the Edge model that allows for the balance between the genetic drift, the gene flow, and the selection till the Pleistocene as well as the over evolution of the global species. This Multi regional hypothesis was proposed in 1984 by A Thorne and the Xinzhi.All of the following are good ways to evaluate written sources of information EXCEPT:

Which of the following is the most energy efficient way to make sure the planet has adequate water for drinking?
Freezing ocean water
Conserving fresh water
Reverse osmosis
Distillation
Answer:
Conserving fresh water or Distillation
Explanation:
Answer:
The conservation of fresh water would be the "most energy-efficient way" to make sure the "planet has adequate water" for drinking.
Explanation:
Freezing ocean water, in the first place, would not be a good option as the ocean water would still be saline even after freezing it. On the other hand, it would neither be feasible nor would it be economical to freeze the ocean water. Though reverse osmosis and distillation are efficient methods of water treatment, it would not be possible to treat water enough to fulfill the drinking water need of the entire planet.Jessica finds out that the government introduced a new trade policy that will increase import tariffs.

Based on what you know about the location of the earth in relation to the sun, why is this called the Goldilocks zone in other galaxies?
Earth is in a place called the Goldilocks zone. If humans were not in this zone, it would be nearly impossible to survive. The Goldilocks zone is not too much of anything. For example, if we were on the planet Mercury or Venus, we could not survive because it is way too hot during the day time and very cold during the nighttime. We have it not to sunny here and not too cold. Without the sun, plants would not grow. Animals, including humans , need plants to eat. We also have not too much sun so the water on our Earth does not all evaporate.
Answer:
It's an area that's an optimal distance from the sun for potentially supporting life.

What's responsible for eutrophication in seawater?
A. Deposition of sediments on shorelines
B. Groundwater infiltration
C. Seafloor spreading
D. Runoff of artificial fertilizers
Answer:
runoff of artificial fertilizers
Answer:
"Deposition of sediments on shorelines" on shorelines is responsible for "eutrophication" in seawater.
Explanation:
The natural process of the addition of nutritional elements to the water is called Eutrophication. The sediments carried by the rivers and streams flowing into the sea get deposited on the shoreline as these rivers and streams lose the strength to carry these sediments further. These sediments are rich in nutritional elements like Phosphorous and Nitrogen. The presence of these elements stimulates the growth of algae to a great extent.how do oil sands affect emissions??
Greenhouse emissions of tar sand, per barrel, are more than conventional crude oil. This is because, it takes more energy to extract the bitumen from the tar sand and more so, to convert the bitumen to usable oil taking up even more energy. This energy is usually derived from burning natural gas. Emissions by tar sand are approximately 100 kg CO2 per barrel while conventional oil is approximately 30 kg CO2 per barrel.
Oil sands affect emissions by producing significant greenhouse gases from burning natural gas to process the viscous oil. The extraction process also leads to environmental degradation, including the destruction of boreal forests and pollution of water sources. These operations result in higher emissions than lighter crude oil and contribute to climate change.
The extraction and processing of oil sands significantly impact greenhouse gas emissions and the environment. Producing oil from oil sands involves burning natural gas to heat and liquefy viscous crude oil, which directly results in the release of carbon dioxide (CO2). It is estimated that for every barrel of oil produced, approximately 25 m3 of gas is used. Even though the energy equivalent of the gas is about 20% of the energy that the produced oil contains, the process generates three times as much greenhouse gas per barrel as compared to lighter crude oil extraction.
Furthermore, the operation leads to the devastation of vast areas of land, including boreal forests, due to strip-mining and the creation of tailings ponds. This results in serious environmental damage, such as the destruction of valuable ecosystems and pollution of water sources. The oil sands development near Fort McMurray is a prime example of such environmental impact, causing a significant increase in greenhouse gases. In fact, by 2015, the emissions from this area were projected to surpass the greenhouse gases emitted by the entire country of Denmark, reflecting the severity of the issue.
In addition to immediate emissions, the long-term environmental costs include permanent ecological damage and potential climate change acceleration. Not only does this method of oil extraction increase emissions during the process itself, but it also involves clear-cutting forests, which are vital for carbon sequestration, further exacerbating the problem.
Based on what you know about the location of the earth in relation to the sun, why is this called the Goldilocks zone in other galaxies? A. It's a region that exhibits a weak gravitational pull, thus maintaining a safe distance from the sun. B. It's an area that doesn't experience any major weather events that could cause mass extinctions. C. It's an area that's an optimal distance from the sun for potentially supporting life. D. It's a region that's unaffected by asteroid or meteor impacts.
The Goldilocks zone, also called Habitable Zone, refers to the region in the space where a planet is located at a distance from its star, which is ideal for living conditions.
For this to be possible, the incident luminosity and the radiation flow on the surface of the planet must be sufficient to maintain the adequate temperature so that water can exist in liquid form (a fundamental requirement for life).
In fact, it is stated that the Earth is in the habitable zone of the solar system and that is why it is capable of housing life.

A cone (straight cone) is a solid generated by the rotation of a right triangle around one of its legs, the base of this solid being a circle.
Its important parts are:
-The axis, which becomes the fixed leg around which the triangle rotates to form the cone.
-The height, which is the distance between the vertex and the base.
-The generatrix, which becomes the hypotenuse of the right triangle.
Answer 2: Rectangle =b. perpendicular cross section of a cylinderA rectangle is a parallelogram whose four sides form right angles ([tex]90\°[/tex]).
It should be noted that two pairs of sides that make up the retangle are parallel respectively and the opposite sides have the same length. In addition, its perimeter is equal to the sum of all its sides.
In addition, a rectangle is the figure obtained when we make a perpendicular cross section of a cylinder.
Answer 3: Triangle =a. perpendicular cross section of a pyramidA triangle is a geometric figure (polygon) with three sides and three interior angles, which sum to [tex]180\°[/tex]. In addition, a triangle has three vertices (points where two of its sides meet or intersect).
Note, if we make a perpendicular cross section of a pyramid, we will get a plane shaped as a triangle.
Answer 4: Circle =c.parallel cross section of a sphereA circle is a flat surface limited by a curved line called circumference. The circumference being the geometric place of the points that are equidistant from the center.
In addition, if we make a parallel cross section of a sphere, the resulting plane will be a circle.
Answer 5: Cylinder =d. shape created when a rectangle is rotated about the y-axisA (circular) cylinder is a geometric body formed by a curved and closed lateral surface and two parallel planes that form its bases.
It should be noted that cylinders are formed when a rectangle rotates around one of its sides.

Explain five different ways that you can respond to global warming.
Answer:
1. Limit the time that you have your AC(air conditioner) is running. Air conditioning uses a chemical called HFC(hydrofluorocarbons), and that chemical is used to keep you cool in your house. HFC is quite toxic for the environment, and it contributes to global warming, because it is called a greenhouse gas by the government. Studies show that the more air conditioning you use, the more likely that more HFC will be released into the environment, worsening the impact it has on global warming.
2. Bike, walk, or use another non-mechanized transportation more. As you have smelled or seen before, cars, buses, trains(not electronic), and many other vehicles emit smoke and other sorts of things. These vehicles emit greenhouse gases such as carbon monoxide, hydrocarbons, nitrogen oxides, and Particulate matter. All of these chemicals really harm the environment, and studies show us that cars and other vehicles produce about 75 percent of CARBON MONOXIDE pollution in the world. By driving less, or using other forms of public transportation less(non electronic), you can reduce the amount of greenhouse gases released into the environment.
3. Use solar power. Solar power is becoming very common, and many people actually have switched to this type of power. The reason? It is very easily renewable. A reason that people should switch to solar power is because other forms of producing power (using turbines, which uses heat, wind, water, steam. etc) have a negative impact on our environment. Solar power can help the environment and the people by reducing greenhouse gas emissions, and it also produces a low cost, low maintenance power source.
4. Don't use plastic items, since plastic production usually produces lots of Carbon Dioxide emissions. Plastic is a useful material, and about 300 MILLION TONS of it is produced every year. Now imagine what it would take to make all this plastic. Have you ever wondered how plastic is made. Plastic is made from natural materials/resources/elements that are found on the Earth. Some of these materials are cellulose, coal, natural gas, salt and crude oil, which are pretty easy to find. These materials are sent to an oil refinery, where first crude oil is refined, and then separated into lighter components which are called fractions. These fractions are then put into one of two processes, and these processes are called polymerization and poly-condensation. Both of these require specific catalysts. Polymerization uses ethylene and propylene to make its plastic. This process is complicated, but during this process, greenhouse gases such as water vapor, carbon dioxide (CO2), methane, nitrous oxide and ozone are released into the environment, and once again, they harm the environment. By using less plastic, you can add less amounts of toxic greenhouse gases into the environment
P.S. Keep in mind, about 300 TONS OF PLASTIC are produced each year.
5. When cows burp, they produce a greenhouse gas called methane. This greenhouse gas is actually one of the most contributing factors to global warming, and it actually is 34 times, more harmful to the environment than carbon dioxide is. Eat less beef, since if there is a higher demand for beef, then the farmers/corporate which produce cows/breed cows will breed more, which adds more methane to the environment. The more demand for cows there are, the more production of cows there will be, which makes more and more methane over time.
In conclusion, by using less natural materials and resources, you can reduce the amount of global warming that is happening to our world right now.

You have been tasked with sorting the rock samples shown into three categories, with two rocks in each category. What attribute would you use to sort these rocks? Which rocks would be in each category? Rocks: obsidian, coquina limestone, granite, soapstone,pumice, and gneiss.
I would sort them into the categories of metamorphic rock, sedimentary rock, and igneous rock.
Igneous rocks are made from the cooling and solidifying of lava or magma. Pumice is one of these rocks, it's made from lava being thrown out of volcano, and rapidly cooling. Obsidian and granite the other igneous rocks in the list.
Sedimentary rocks are made from the sedimentation of smaller particles. Coquina limestone is one of these - it's made from the sedimentation of the shells of dead animals.
Metamorphic rocks are rocks which are created by extreme heat and pressure. Essentially, they used to be a different kind of rock, and now they're metamorphic rocks. Gneiss and soapstone are both metamorphic rocks.
So here are your final answers:
Igneous: Granite, Obsidian, Pumice
Sedimentary: Coquina limestone
Metamorphic: Gneiss, Soapstone
Hope this helped!

What percent of all farms in the US are small family farms?
A. 30%
B. 50%
C. 70%
D.90%
The correct answer is 88%, however, it is not in the choices so maybe (d.) 90% since it is near to the accurate answer. 88%-90% of al farms in the United States are small family farms.
Final answer:
The correct answer is 90%, indicating that small family farms still make up the majority of all farms in the United States, despite economic pressures and development reducing their number over time.
Explanation:
According to the United States Department of Agriculture (USDA), a small family farm is defined as one with less than $250,000 in gross cash farm income and where the majority of the business is owned by individuals or a family. These small family farms make up a substantial portion of all farms in the U.S. As of recent data, the correct answer to the question, 'What percent of all farms in the US are small family farms?' is 90%. This reflects a longstanding tradition of family-operated farms in the United States, though economic pressures have led to a reduction in the number of farms overall, particularly affecting small farms.
Economically, it has become increasingly difficult for new farmers to enter the business due to high operational costs, and productive farmland is also being lost to urban and suburban development. Despite these challenges, the majority of farms in the United States are still classified as small family farms.
The weathering of the Earth's surface is known as
erosion is to soil/rock; corrosion is to metals
erosion is by natural forces (wind, water), corrosion is by chemical
erosion is extremely slow over many years; corrosion is still slow but typically faster than that
weathering = natural force
earth's surface = soil/rock
The weathering of the Earth's surface is known as Erosion.
Explanation:
Weather is describes as the decomposition or melting of rocks and minerals on the earth's surface. Water, ice, acids, salts, plants, animals and temperature are the components of weather. It is true that the weathering of the Earth's surface is called as erosion.
It is a action of natural forces that abrades the rocks and soil. It helps to smooth the rough and sharp rock surfaces in the production of soil. It is a chorography analyses and part of the rock cycle. Erosion occurs on the surface and does not affect the shell and cores.

Which of the following statements does not describe a likely effect of a society's being culturally isolationist? A. Internet access would be widespread and uncensored. B. Citizens would have few civil liberties, such as freedom of speech and religion. C. The government would try to limit the influence of outside cultures. D. Few foreign movies, television shows, or news programs would be broadcast.
Answer:
A. Internet access would be widespread and uncensored
Explanation:
The societies that are culturally isolated are very restricted by their governments. The governments tend to implement policies which do not allow for contact with the other societies. They tend to censor most of the things, including the social media (if its allowed at all), and the cultural products from the other places in the world are forbidden or minimized. This results in isolation of the people from that society, so their culture is unaffected by the other cultures, often making that society far behind the others. A prime example of this is North Korea in the modern world.

The mixed economy types are economy types that have strong elements from both the market economies, and the planned economies. Usually, this type of economy has developed from planned economy type, but because of adaptations in order for the economy to progress and develop, lot of the elements of the market economy has been implemented as well. This results in an economy where the government is still holding onto the most important natural resources in order to provide economic security, while the private sector is also thriving and develops very well without being limited by the government, but instead having it as an economic partner. A perfect example of this is China.
