How to grow a virus in petri dish? You cannot grow a virus in a petri dish. The reason is that viruses are considered to be non-living. They do not possess active reproduction machinery on their own. Viruses instead hijack a host cell's machinery, injecting its own DNA or RNA, allowing the host cell to reproduce the virus.

Positron emission tomography scan (PET scan) Positron emission tomography scan (PET scan) Positron emission tomography (PET) is a nuclear imaging technique that creates detailed, computerized pictures of organs and tissues inside the body. A PET scan reveals how the body is functioning and uncovers areas of abnormal metabolic activity. During a PET scan, the patient is first injected with a glucose (sugar) solution that contains a very small amount of radioactive material. The substance is absorbed by the particular organs or tissues being examined.

Bacteria Growing Experiments in Petri Plates Prepared petri dishes should be refrigerated until used and always stored upside down (i.e media in upper dish, cover on bottom). This keeps condensation which forms in the lid from dropping onto and disrupting the bacteria growing surface. Prepare sterilized water by boiling water and letting cool to room temperature.

- In geology, petrifaction or petrification is the process by which organic material is converted into a fossil through the replacement of the original material and the filling of the original pore spaces with minerals. common source of silica is volcanic material. Studies have shown that in this process, most of the original organic matter is destroyed. Silicification most often occurs in two environments-either the specimen is buried in sediments of deltas and floodplains or organisms are buried in volcanic ash.
