Answer:

Here are five fast facts to get you up to speed:

1. NUCLEAR POWER PLANTS PRODUCED 790 BILLION KILOWATT HOURS OF ELECTRICITY IN 2019

The United States is the world’s largest producer of nuclear power. It generated 790 billion kilowatt hours of electricity in 2020, surpassing coal in annual electricity generation for the first time ever. Commercial nuclear power plants have supplied around 20% of the nation’s electricity each year since 1990.

2. NUCLEAR POWER PROVIDES 52% OF AMERICA’S CLEAN ENERGY

Nuclear energy provided 52% of America’s carbon-free electricity in 2020, making it the largest domestic source of clean energy.

Nuclear power plants do not emit greenhouse gases while generating electricity.

They produce power by boiling water to create steam that spins a turbine. The water is heated by a process called fission, which makes heat by splitting apart uranium atoms inside a nuclear reactor core.

3. NUCLEAR ENERGY IS THE MOST RELIABLE ENERGY SOURCE IN AMERICA

Nuclear power plants operated at full capacity more than 92% of the time in 2020—making it the most reliable energy source in America. That’s about 1.5 to 2 times more reliable as natural gas (57%) and coal (40%) plants, and roughly 2.5 to 3.5 times more reliable than wind (35%) and solar (25%) plants.

Nuclear power plants are designed to run 24 hours a day, 7 days a week because they require less maintenance and can operate for longer stretches before refueling (typically every 1.5 or 2 years).

4. NUCLEAR HELPS POWER 28 U.S. STATES

There are currently 94 commercial reactors helping to power homes and businesses in 28 U.S. states. Illinois has 11 reactors—the most of any state—and joins South Carolina and New Hampshire in receiving more than 50% of its power from nuclear.

5. NUCLEAR FUEL IS EXTREMELY DENSE

Because of this, the amount of used nuclear fuel is not as big as you think.

All of the used nuclear fuel produced by the U.S. nuclear energy industry over the last 60 years could fit on a football field at a depth of less than 10 yards.

Answer:

Antinuclear antibodies are autoantibodies that bind to contents of the cell nucleus. In normal individuals, the immune system produces antibodies to foreign proteins but not to human proteins. In some cases, antibodies to human antigens are produced.

1. Nuclear waste:

The waste generated by nuclear reactors remains radioactive for tens to hundreds of thousands of years . Currently, there are no long-term storage solutions for radioactive waste, and most is stored in temporary, above-ground facilities. These facilities are running out of storage space, so the nuclear industry is turning to other types of storage that are more costly and potentially less safe .

2. Nuclear proliferation:

There is great concern that the development of nuclear energy programs increases the likelihood of proliferation of nuclear weapons. As nuclear fuel and technologies become globally available, the risk of these falling into the wrong hands is increasingly present. To avoid weapons proliferation, it is important that countries with high levels of corruption and instability be discouraged from creating nuclear programs, and the US should be a leader in nonproliferation by not pushing for more nuclear power at home .

3. National security

Nuclear power plants are a potential target for terrorist operations. An attack could cause major explosions, putting population centers at risk, as well as ejecting dangerous radioactive material into the atmosphere and surrounding region. Nuclear research facilities, uranium enrichment plants, and uranium mines are also potentially at risk for attacks that could cause widespread contamination with radioactive material .

Define embryonic stem cells. Explain the pros and cons of Embryonic Stem Cells
just olya [345]

Answer:

Embryonic stem cells are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre-implantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells.

Explanation:

 

 Adult Stem Cells  

Embryonic Stem Cells      

Induced Pluripotent Stem Cells      

Pros

Trans differentiate and and reprogramming of these cells is possible but is not well studied

Thought to be less likely to be rejected if used in transplants

Success has already been demonstrated in various clinical applications  

Can maintain and grow for 1 year or more in culture

Established protocols for maintenance in culture

ESCs are pluripotent cells that can generate most cell types

By studying ESCs, more can be learned about the process of development

 

Abundant somatic cells of donor can be used

Issues of histocompatibility with donor/recipient transplants can be avoided

Very useful for drug development and developmental studies

Information learned from the “reprogramming” process may be transferable for in vivo therapies to reprogram damaged or diseased cells/tissues  

Cons

Limitations on ASC ability to differentiate are still uncertain; currently thought to be multi or unipotent.

Cannot be grown for long periods of time in culture

Usually a very small number in each tissue making them difficult to find and purify

Currently there is no technology available to generate large quantities of stem cells in culture

 

Process to generate ESC lines is inefficient

Unsure whether they would be rejected if used in transplants.

Therapies using ESC avenues are largely new and much more research and testing is needed

If used directly from the ESC undifferentiated culture prep for tissue transplants, they can cause tumors (teratomas) or cancer development    

Methods for ensured reproducibility and maintenance, as differentiated tissues are not certain.

Viruses are currently used to introduce embryonic genes and has been shown to cause cancers in mouse studies

An animal cell with a 30% salt solution is placed in a beaker with a 20% salt
AleksAgata [21]

Answer:

the animal cell will burst

Explanation:

If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.

Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.

Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.
