Answer:
Its fossil energy non renewable source
Explanation:
Answer:
Coal vs Natural Gas Coal is a sedimentary rock with a high concentration of hydrocarbons and carbon. Given that it takes millions of years for coal to develop, it is categorized as a nonrenewable energy source. Coal is combustible and typically black or brownish black in color. Natural gas is a naturally occurring mixture of gaseous hydrocarbons, mostly methane, with small traces of other higher alkanes. Coal and natural gas have different benefits, effects on the Earth, and impacts on human health. Natural gas is a fossil fuel; however its global warming emissions are significantly smaller compared to those from coal or oil. When combusted in a modern, efficient natural gas-power plant, natural gas releases between 50 and 60 percent less carbon dioxide (CO2) than pollution from an average modern coal plant. The impacts of human health due to air pollution from both coal and natural gas can lead to asthma and breathing issues, brain damage, heart problems, cancer, neurological disorders, and early mortality. These conditions are from the releasing of mercury, lead, sulfur dioxide, nitrogen oxides, particulates, and other heavy metals in to the air. In 2021, electricity producers in the United States paid roughly $4.98 per million British thermal units for natural gas. Coal power plant operators, on the other hand, paid an average of 1.98 US dollars; in simpler terms, the cost of generating electricity is cheaper using coal. Coal is a reliable, cheap source of power. It is easy to store, reduces dependence on oil, and creates many jobs. On the other hand, when burned to create power, natural gas produces roughly half the carbon dioxide (CO2) and one-tenth the air pollutants produced by coal. By using gas instead of coal, there is significant potential to cut near-term CO2 emissions and air pollution by using gas over coal. It is adaptive. A gas-fired power plant starts and stops much faster than a coal-fired unit. Both gas and coal have plentiful pros and cons however gas is the better one to use. Gas is more abundant and pollutes more than coal. Though coal is cheaper, the effects on the environment and human health are not worth the gamble. https://www.shell.com/energy-and-innovation/natural-gas/natural-gas-and-its-advantages.html http://groundtruthtrekking.org/Reports/Coal-Electricity-Prices-Externalities-Analysis/1/Coal-Electricity-Prices-Externalities-Levelized-Cost/ https://www.statista.com/statistics/189180/natural-gas-vis-a-vis-coal-prices/
Why does mitosis occur???
Answer: Mitosis is the process in cell division by which the nucleus of the cell divides (in a multiple phase), giving rise to two identical daughter cells. Mitosis happens in all eukaryotic cells (plants, animals, and fungi). ... Mitosis is the reason we can grow, heal wounds, and replace damaged cells.

A suitcase with a mass of 2 kg has a weight of 18 N on a particular planet. What is the acceleration due to gravity on that planet?
Answer:
acceleration due to gravity: g= 9 m/s^2
Explanation:
m=2kg
w= 18 n
w=mg
g= w/m
g=18/2
g= 9m/s^2

Four children pull on the same stuffed toy at the same
time, yet there is no net force on the toy. How is this
possible?
Answer:
The forces the children are exerting on the object balanced one another.
Explanation:
Equal forces acting on an object in opposite directions.
Hope this helps!
Answer:
Sample Response: Forces are either positive or negative vectors, depending on the direction in which the force is acting. The net force is the sum of all of the forces acting on an object. If the children pull on the toy with the same force in opposite directions, the forces will be perfectly balanced and cancel out, leaving a net force of zero.

Answer:
asexual and sexual.
Explanation:
In plants there are two modes of reproduction, asexual and sexual. There are several methods of asexual reproduction such as fragmentation, budding, spore formation and vegetative propagation. Sexual reproduction involves the fusion of male and female gametes.
what kind of bond forms when atoms in a molecule do not share their electrons equally
a. an ionic bond
b. a metallic bond
c. a polar bond
d. a hydrogen bond
Answer:
A polar bond
Explanation:
Ionic bond don't share but one atom accepts electron while the other gives away electron Metallic bond are held by metals and they contribute their outer valency electrons to the electron cloud thus making them positive A polar bond deals with the share of unequal electron (I.e. Covalent polar bond) A hydrogen bond is covalently bonded to highly electronegative elements of small atomic sizeResearchers are investigating the incidence of algal blooms in neighborhood ponds. In summer, they collect water samples from over 100 neighborhood ponds in Dallas, Texas and surrounding cities. They also surveyed residents in each neighborhood to collect data such as average lot size, average home value, average resident income, and lawn care methods. The researchers found that neighborhoods with large lots, high home values, and high income levels were likely to use automatic sprinklers and synthetic fertilizers on their lawns. These same neighborhoods were very likely to have abundant algae in their ponds. Based on this research, which conclusion provides the best explanation for why algae proliferate in neighborhood ponds?
Answer:
Excessive synthetic fertilizer that washes into ponds may be the reason for which algae become so abundant.
Explanation:
Algal blooms that feed on fertilizers can deplete oxygen in water, thereby producing inhospitable ponds. In this regard, it has been shown that the runoff of fertilizers from farms (which are rich in nitrogenous matter) may cause algae to become abundant in coastal environments, depleting oxygen in the water and killing the living organisms that inhabit these areas.

Which of the following was the leading cause of global fossil carbon emissions in 2004?
a. petroleum
b. coal
c. natural gas
d. cement production
Answer:
The answer is a. petroleum
Explanation:
I just took the test and got it right.
The leading cause of global fossil carbon emissions in 2004 was petroleum. Thus, the correct option for this question is A.
What is Carbon emission?Carbon emission may be defined as the process of liberation of greenhouse gases like carbon dioxide and/or their precursors into the atmosphere over a specified area and period of time. These emissions are significantly contributing to climate change across the world.
When it comes to the global fossil carbon emissions in 2004, the major cause of that was due to petroleum. During that time, people utilize a large amount of petroleum in burning activities. This stimulates the rate of carbon emission in the entire atmosphere which is harmful to the health of living organisms.
Therefore, the leading cause of global fossil carbon emissions in 2004 was petroleum. Thus, the correct option for this question is A.

How would you slow a herd down
If its a herd of caddle or bulls, Somone on a horse would be riding next to the herd slowing turning the herd back to where they belong
Answer:
capture the leader of the herd, or cut them off.
Explanation:
the herd will follow their leader, so if you control the leader then you control the heard; if the herd doesn't have a leader or you cannot control the leader, then cut them off by blocking their way until they are going in the direction you want them to or have stopped.
The fossils of a few organisms are shown below. The first image is a bird, the second image is a dinosaur, and the third image is an Archaeopteryx. The dinosaur fossils were obtained from the lower sedimentary layer, and Archaeopteryx was found above it. The fossils of the bird were found on the topmost layer, which suggests that they’re the_____ . This information also suggests that Archaeopteryx _______.
-21 POINTS-
Answer:
They're the Youngest. This information also suggests that Archaeopteryx was once thought to be the oldest known fossil bird.
Explanation:
Hope this helps.
Based on the principle of superposition, we can conclude that the topmost layer is the youngest. Hence, the fossil of birds is the youngest, while Archaeopteryx is younger than dinosaur fossil.
According to the principle of superposition, sedimentary deposits are layered such that, the oldest layer is at the bottom and the youngest is the topmost layer.
Hence, dinosaur fossil are the oldest, followed by Archaeopteryx, then birds.
