: Research coal and natural gas as a source of energy.
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/

PLEASE HURRY Which mutation results in the production of molecules that can be used as a source of energy?
a mutation that causes bacteria to fight off antibiotics
a mutation that breaks down the sugar in milk, lactose
a mutation that changes the color of a part of a flower
Answer:
It is the second one.
Explanation:
I know for a 100% chance because I just finished this test and got a 100.
Answer:
B.(a mutation that breaks down the sugar in milk, lactose)
Explanation:
Your colleague asks you to verify her findings about a new polymer intended for use as a vascular graft. It must be reasonably elastic; otherwise, the blood will be constricted and increase its flowrate downstream with each pulse of the heart. She found that the material was sufficiently elastic for use inside the body. After running a tension test, you find that it is too brittle for use. Your colleague reviews your protocol and declares that you have either graduated from Duke or checked your eyelids for light leaks during Dr. Brudno's BME 203 class, because it definitely is adequate. Describe two mistakes you may have made. Put a (1) and (2) before each of your reasons.
Answer:
1.Vascular tube is used for vascular surgery and is very small in size with very small diameter and thickness,thus a little change in environment can also affect there result.
2.When testing for tension in the polymer it is very important to consider the strain rate as the increase in strain can cause the material to break.Therefore not only tension test but also strain test is required.

Please help!!! how can a sedimentary rock become a sedimentary rock???
Answer:
Sedimentary rocks are made of sand, gravel, mud and other materials. They go through a 5 step process to be made.
Explanation:
1) first weathering breaks down material that will be used to form the rock.
2) next erosion picks up the sediment via wind, water, or glacier
3) the sediment is then transported via wind, water, or glacier
4) Then deposition occurs. (depositing the sediment)
5) Lithification (turning the sediment to rock)
Use the image to answer the question.
A researcher studying a line of cancer cells notices that cellular content of RhoBTB3 and Cyclin E1 increase and decrease through the cell cycle.
a. He hypothesizes that RhoBTB3 signaling regulates the production of Cyclin E1 and the entry of the cell into mitosis. Based on the data below, explain why his results do not support this hypothesis. Identify what conclusions are supported by this data.
b. Suppose that the researcher can engineer a cell line in which RhoBTB3 expression can be induced by the addition of a drug. Design an experiment using this cell line to test whether RhoBTB3 regulates the production of Cyclin E1. Describe what results he can expect if his hypothesis is correct.
I'm not sure about part b but here's the answer for part a
Explanation:
The experimental data shows that the RhoBTB3 expression increased after 12 hours and reached it's peak at 18 hours, which occurs in the G2 phase. The expression of Cyclin E1, however, started to increase after 8 hours, peaked at 14 hours, and remained there for 2 more hours before starting to decline. This shows that the highest level of the Cyclin E1 expression occurred in the S phase and initiated at the end of the G1 phase. His hypothesis is incorrect because if RhoBTB3 signaling did regulate the production of Cyclin E1, then the peak should have occurred prior to Cyclin E1.

What is a possible result of an increased amount of CO2 in the atmosphere?
Answer:
There are no options to this question, however, it can be answered using general knowledge. The answer is GLOBAL WARMING
Explanation:
Carbon dioxide, commonly called CO2, is one of the gaseous constituent of air. It is considered to be the most important greenhouse gas i.e. gases that have the ability to trap heat from the surrounding atmosphere. Due to this ability, CO2 in addition to other gases like methane are known to contribute to a phenomenon called GLOBAL WARMING.
GLOBAL WARMING is an increase in the atmospheric temperature of the Earth due to the effect of greenhouse gases. Global warming is a concern for the world populace, hence, an increase in the concentration of gases like CO2 in the atmosphere will lead to GLOBAL WARMING (an increase in Earth's atmospheric temperature).
What happens to all the sun's energy that does not get stored in the producers?
Answer:
it is just lost as heat. If plants do not absorb the light (or algae or cyanobacteria), then nothing is left to absorb the light. Thus, it is lost as heat.
Explanation:
China's economy is growing very quickly and requires a large amount of energy. Most of the energy consumed by the country comes from a nonrenewable energy source. Which of the following is a nonrenewable energy source?
A
coal
B
hydroelectric
C
solar
D
wind
Fun fact ; I made this sentence while brushing my teeth , you can tell with how this sentence is lowercased and multiple typos
Answer:
A non-renewable source of energy is coal.
Explanation:
The mineral coal is a brown or black rock, of sedimentary origin, that comes from organic matter, so it is considered a fossil fuel.
Currently, coal is used as an energy source, since its combustion produces a great amount of heat. However, the speed with which coal is consumed is faster than its production —which can last millions of years— so it is considered a depletable or non-renewable energy source.
The other options, such as hydroelectric, solar and wind energy are renewable energy sources.

What amino acids are being carried by the tRNA
Answer:
Explanation:
Each tRNA can only carry one amino acid. The tRNA CODES for ONE amino acid through its 3 base codons. The 3 codons result in a possibility of 64 combinations and since 3 of those 64 code for STOP there are a potential 61 amino acids coded for by a tRNA, but each tRNA only carries one of those potential amino acids. read more

Scientific explanation about how your body reacts to getting stung by yellow jackets?
What goes on in your body (why your toungue feels funny, welts appear over your body, and why it gets hard to breathe)? What chemicals are involved?
Answer:
the answer is under explanation.
Explanation:
The body produces a chemical known as histamine, in an effort to protect the body from foreign substances, which is partly what causes the swelling and itching. Taking an over-the-counter antihistamine such as Benadryl right after getting stung can reduce these symptoms.
