differentiate between radioactivity and biotechnology?
89157
radioactivity is the decay of an atom by emmision of radiation. Biotechnology is the use of biology to improve something, be it health or living conditions etc.

radioactivity is the spontaneous emission of alpha beta or gamma rays from a radioactive substance to attain stability.\nthey can be used as tracers to know the path of ne reaction\nsome of them can be used to treat cancer like co-60. and uranium is already used in nuclear reactors for generating electricity.

Good question.  \n\nFirst biotechnology is essentially the use of bacteria or yeast or products of these living organism like enzymes for the use or production of drugs.  It has many other applications like alternating certain bacteria to be able to eat and degrade oil spills, for instance.  Over the past 2-3 decades we have made tremedulous strides in understanding the mechanisms of cells.  In the process, we have developed new technology to be able to manipulate cellular function.  For instance, mass producing strands of DNA, being able to insert these code sequences into bacterium dna,  forcing the bacterium to make these codes into proteins which benefit the whole of society.\n\nWhat is the difference between the pharmaceuticals and biotech.  In general pharmaceutical companies make medications by chemical reaction.\n\nBiology is a must.  It provides the foundation for later studies.  Yes high school biology can be a drag. ( i always hated learning about different plant reproduction or different dinosaur era or evolution.)  But stick with it cause.  The courses become more advanced when you go to college.

Are you looking at any protein in particular?  Look up in situ hybrdization for proteins ( at least it will give you an idea where it is localised).  I think that it would really depend on the system ad proteins that you want to study, so I am not sure how much else I can tell you, sorry.

What then is biotechnology? The term brings to mind many different things. Some think of developing new types of animals. Others dream of almost unlimited sources of human therapeutic drugs. Still others envision the possibility of growing crops that are more nutritious and naturally pest-resistant to feed a rapidly growing world population. This question elicits almost as many first-thought responses as there are people to whom the question can be posed. \n\nIn its purest form, the term "biotechnology" refers to the use of living organisms or their products to modify human health and the human environment. Prehistoric biotechnologists did this as they used yeast cells to raise bread dough and to ferment alcoholic beverages, and bacterial cells to make cheeses and yogurts and as they bred their strong, productive animals to make even stronger and more productive offspring.

radioactivity is caused by a instability in the forces holding the nucleus of an atom. A atom emits radiation to allow it to change into a more stable element or isotope.

not much\nsomething else decays into radium, or is recombinant

When you work with unsealed radionuclides, used as tracers in a cell laboratory, you need to be checked periodically to see that you have not ingested any. I worked with soluble chromium-51, used to watch the destruction of lymphocytes (white blood cells). The way you get checked is that you submit a urine sample in a clean, clear container. Everyone gets the container, fills it, and was to bring it back to a technician. \n\nThe technician was a very beautiful redhead woman, Bernie. She was our electron-microscopist. We occasionally played small tricks on her, she on us. Everyone flirted with her. Harmless things. We were grad students, she was used to our stupid boy things.\n\nSo... one day I got the container and was supposed to give her a sample. Instead I went down to the cafeteria and bought some apple juice. I let the juice warm to room temperature. Then I poured it in the clean urine sample container. I know, you see this coming, right.  I went up to the lab where Bernie was.\n\n"Hey, Bernie," I said, "where do you want the sample?" She indicated over on the bench. She was busy with some small group of folks.\n\n"Bernie," I called again. She turned and looked. "I think it looks a little weak. I think I will run it through again." With that I opened the "urine" sample (really apple juice, of course) and drank it in one gulp.\n\nBernie turned bright red, as only a true redhead can, all the way to her roots. No freckles were left, she was beet red. She sputtered my name and then said, pointing to the people with her, "These are the representatives of the People's Republic of China who are touring our lab."\n\nGulp!  Well, guess they saw we Americans were pretty much what they thought we were.

Nor really.  Human metabolic processes occur on the atomic level (chemistry) whereas fusion occurs on the subatomic nucleus level.\n\nHowever, if exposed to radiation or similar forces, human bodies can undergo nuclear reactions with such radiation.  Incoming radiation can interact with the protons and neutrons of cells' nuclei causing a nuclear reaction.

Dosimetry is the measurement of doses in matter and tissue from ionizing radiation (radioactivity, alfa decay, gamma decay, beta decay).\n\nDoses are measured in grays (Gy) for matter or sieverts (Sv) for biological tissue. \n\nThe dose refers to the amount of energy or damage deposited in the matter, and should not be confused with the unit of radioactive activity (becquerel, Bq). \n\nDoses can be measured in places other than where the radioactive decay occurred.

Usually older DNA strand has post transcription modification compared to newer DNA strands (methylation).\nAs for experiments to tell which one is old vs. new, you can do a purse-chase experiment using radio-labeled dNTPs.

There may be some, but it's too little to be a health concern.  Even the ambient radiation at Bikini Atoll is not extreme; the danger comes from the local trees (and any local crops), which would take up and concentrate radioisotopes in their tissues.

For the first question, , I think C is the least correct.  Alpha and beta emissions are particles, not rays.  B is also suspect, because not all radioactive emiissions are both particulate and energy.\n\nFor your true/false question, the answer is FALSE.  An alpha emission reduces the atomic number by 2, and reduces the atomic weight by 4.

The Nuclear Regulatory Commission's mandate to protect public health and safety and the environment includes regulation of the medical use of radioactive (byproduct) material in the fields of nuclear medicine, radiation therapy, and research.\n\nMedical use of radioactive materials falls broadly into two categories: diagnostic and therapeutic procedures. Diagnostic procedures using radioactive materials, such as those used in nuclear medicine, involve the use of relatively small amounts of radioactive materials to facilitate imaging of certain organs. Two examples of nuclear medicine procedures are the use of technetium-99m in the diagnosis of bone, heart or other organs and radioactive iodine in the imaging of the thyroid gland. The radioactive materials typically are injected into the patient and allow physicians to locate and identify tumors, size anomalies, or other physiological or functional organ problems.

This is not a pure biology question. Should be bio-chemistry.

The pure and applied science can be differentiated as:\nPure science - motivated by curiosity \nApplied science - designed to answer specific questions. \n\nGiven these definitions, I will later argue that governments have a special responsibility to fund basic science while applied science can generally be left to industry. The distinction is, of course, not always entirely clear cut, and the term "strategic research" is sometimes used to describe science in an intermediate category which appears to have a good chance of applications even if it is done to satisfy curiosity, and is leading to new fundamental understandings. An example is research on the properties of two-dimensional semiconductors.\n\nThe difference between pure, and applied science was beautifully illustrated by J.J. Thomson - the discoverer of the electron - in a speech delivered in 1916 :\n\n"By research in pure science I mean research made without any idea of application to industrial matters but solely with the view of extending our knowledge of the Laws of Nature. I will give just one example of the "utility" of this kind of research, one that has been brought into great prominence by the War - I mean the use of X-rays in surgery......Now how was this method discovered? It was not the result of a research in applied science starting to find an improved method of locating bullet wounds. This might have led to improved probes, but we cannot imagine it leading to the discovery of the X-rays. No, this method is due to an investigation in pure science, made with the object of discovering what is the nature of Electricity."
