What document identifies the type and quantity of radioactive material that are allowed to be possessed?
A radioactive material license or permit issued by the appropriate regulatory agency (such as the Nuclear Regulatory Commission in the United States) identifies the type and quantity of radioactive material that an entity is allowed to possess. This license outlines the specific conditions and restrictions for handling, storing, and using radioactive materials.
What did the pulse-chase experiments allow Palade to observe?
It allowed him to see the pathway of protein secretion from the rough ER to the golgi apparatus via vesicles to the nuclear membrane via vesicles, and then out of the cell. He was able to see it by staining radioactive proteins and looking at them at different times after the injection of the radioactive amino acid occured to see where the proteins were.
How do you synthesise zeolites?
Zeolites can be synthesized through hydrothermal methods by mixing a source of silicon and aluminum with a strong base and water at high temperatures. The mixture is then allowed to crystallize, forming the zeolite structure. Other methods include sol-gel synthesis and ion-exchange processes.
Before 1828 it was believed that organic compounds could be made only by a?
process called vitalism, which suggested that living organisms had a special force that allowed them to create organic molecules. However, in 1828, Friedrich Wöhler successfully synthesized urea from inorganic compounds, disproving the theory of vitalism and opening the door to the field of organic chemistry.
Describe the experimental design that allowed Hershey and Chase to distinguish between the two options for genetic material?
Hershey and Chase knew that the particular phage they worked with has two basic components: DNA on the inside, coated with protein on the outside. In their expt theylabelled phages with radioisotopes . For one batch of infecting phages, they used a radioactive isotope of sulfur to label only the phages' protein coats.In another batch of phages, they used a radioactive isotope of phosphorus to label only DNA. Next, they allowed each batch of phages to infect separate cultures of nonradioactive bacterial cells. They then whirled each culture in a blender to shake loose any parts of the phages that remained outside the bacterial cells. Result of expt. confirmed that only DNA of phage entered bacteria .

How would three radioactive samples affect you if you were allowed to handle it?
It depends upon what the radioactive samples are. If you handle a glow-in-the-dark wristwatch, then there will be no observable effects. If you handle a 'hot' piece of Cesium, say, you could lose your arm.
Marie curie and Pierre curie how did they help the medicine industry?
Their discoveries of the elements that produce radiation allowed for the medical practices of using radioactivity to treat cancer. Some of these practices, for example placing radioactive 'seeds' near cancerous growths are still practiced today. Marie Curie also invented portable X-Ray machines she took into the battlefields of WWI to help locate shrapnel and bullets in injured soldiers.
Are you allowed to copy the choreography from a Broadway show for your own production?
If you are claiming it as your own choreography then no. Shows of that nature are subject to copyright and may require permission to use or replicate aspects of the show.
What radioactive waste can be stored for decay and then safely released into the environment?
Low-level radioactive waste, which includes items like contaminated clothing, tools, and medical equipment, can often be stored for decay and then safely released into the environment after sufficient time has passed for its radioactivity to diminish to safe levels. This process typically involves monitoring the waste until its activity level falls below regulatory thresholds. Additionally, certain isotopes with short half-lives can be allowed to decay in controlled facilities before disposal. Proper management and adherence to safety regulations are essential to ensure environmental protection.
In a second experiment mice were allowed to breathe oxygen gas O2 laced with radioactive oxygen in this experiment the radioactive oxygen atoms quickly showed up in?
the mice's bodies in place of normal oxygen atoms, indicating rapid uptake of the radioactive oxygen. This demonstrates the efficient absorption and distribution of oxygen in the body by living organisms.
Why did Hershey and Chase's experiment work only because of the use of radioactive labeling?
Hershey and Chase's experiment worked because they used radioactive labeling to track the DNA and protein separately. This allowed them to determine that only the DNA, not the protein, was passed on to the next generation of bacteria.
Why aren't the Muslims allowed to see their god?
because Allah is supreme human can't affort the holy light of Allah and will be distroyed there are many things we cannot see for ex: radioactivity that we cannot see it but it can even kill us
What situations are modeled by exponential functions?
Some examples include: * Growth of populations, under certain circumstances * Radioactive decay * In quantum physics, the probability of finding a particle at a specific point * The temperature of an object, when it is allowed to cool down * The charge on a capacitor which is allowed to discharge
How did Hershey and chase show that DNA was the molecule that carried the genetic code?
Hershey (you know, Alfred Hershy) and Chase (you know again, Martha Chase) did some experiments with Bacteriophages (you know, viruses that affect Bacteria). What they did in the experiment was that, they grew some of these Bacteriophages on a medium which contained radioactive Sulphus(S)(remember, radioactivity can be detected easily). Then, they also took some other Bacteriophages. But, they were grown on radioactive Phosphorur(P)..... (Don't 4get(that's forget)), DNA also has Phosphorus in it (DNA = Nitrogen bases + Pentose sugar + Phosphorus). Now, back to the experiment ------ The Bacteriophages that were grown on radioactive Phosphorus contained radioactive DNA. But they didn't have any radioactive protein coat. (remember viruses have a protein coat covering their DNA?) Then, bacteriophages (please call them B from now, but not in the exams), which were grown in S (radioactive sulphur, remember?), had a radioactive protein coat (protien coats are made up of sulphur and some other elements), but no radioactive DNA........ That was the first part....................... Now, the next one.......................... Radioactive B's, from both P and S were allowed to attach to E.coli (Esterichia coli) bacteria as an attack (or infection). After infection, The protein coats were removed by agitating (stirring real fast) in a blender (they're still not removed). Then, these virus particles (protein coats) wer removed by centrifugation (using centrifugal machine). Then, the third big step....................................… The observation part....................................… It was observed that, some bacteria were radioactive and many were not. Also, it was observed that, bacteria which were attacked by B (Bacteriophage) having radioactive DNA were the ones which were radioactive..... Also that, bacteria which were attacked by B having S weren't radioactive...... So, it lead to the point that proteins didn't pass into bacteria, but it was the DNA that did...... So, DNA was concluded to be the genetic material...... Viruses were chosen because they only had genetic meterial & coat This is from yahoo anwsers btw
