Nutrient Growth Medium

It is a culture medium or nutrient broth for all kinds of microorganisms to grow properly and create their colony. This matrix provides support to increase the population of microbes through the method of cell proliferation. It is regarded as the food material for those organisms. It is a type of in vitro mechanism, in which the development of life is processed outside the host body. It can be solid, semi-solid, or liquid in nature. Different kinds of cells develop in different types of media.

Heliox is a helium‑oxygen mixture that may be used in scuba tanks for divers working at great depths. It is also used medically as a breathing treatment. A 5.25 L tank holds helium gas at a pressure of 1734 psi. A second 5.25 L tank holds oxygen at a pressure of 461.0 psi. The two gases are mixed in a 5.25 L tank. If the temperature remains the same throughout the process, what is the pressure of the gas mixture in the tank? Assume ideal gas behavior.

Many radioactive isotopes are used in medicine for imaging and treatment purposes. The specific isotopes used depends on the particular organ or body system being studied (for example, Xe-133 is used to image lung function and blood flow.) Technetium-99m is a common radioactive isotope using for a variety of medical applications. It is produced from the decay of Molybdenum-99 and has a half-life of 6.01 hours. What are some of the applications of Tc-99m? While harder to access, another radioactive isotope of technetium, Tc-93, has a half-life of 2.73 hours. If it were easier to harvest, would this be a good substitute for Tc-99m? (remember to explain why for full credit) While Tc-99m has a half-life of 6.01 hours, its decay product has a half-life of 213,000 years. While the medical community considers it to be reasonably safe, within the limits of testing, does this make sense considering both chemical and biological principles?
