Viruses are typically grown in living cells, such as bacteria or animal cells, as they need a host to replicate. Specialized growth media, such as culture medium or cell culture media, are used to provide the necessary nutrients for the cells and viruses to grow. These growth media are usually supplemented with amino acids, sugars, salts, and vitamins to support viral replication.
The control variable in a mold experiment would typically be the conditions in which no mold is allowed to grow. This could involve using a sterile environment or a substance known to inhibit mold growth as a control to compare against experimental conditions.
How soon a specimen of something must reach the laboratory depends partly on the reason for which it is being sent to the laboratory, environmental conditions during storage and transit, and the stability of the substances the specimen consists of. A urine specimen must be refrigerated during storage and transit and arrive in the lab within an hour or two. It cannot sit out because warmth will allow bacteria, if present, to begin to grow in numbers.
Diamonds formed underground have more time to grow and develop under high pressure and temperature, leading to larger crystals. In a laboratory, diamonds are typically created using a faster process that may not allow for the same level of crystal growth, resulting in smaller sizes.
Nitric acid is used in the production of fertilizers to help plants grow. It is also used in the production of explosives, as well as in cleaning and etching metals. In the medical field, nitric acid can be used for certain chemical reactions and in laboratory testing.
You make a prediction based on something you know. So I know that table salt is sodium chloride (2 atoms). Epsom Salt is Magnesium Sulfate (MgSO4) which is 6 atoms. If we assume that the crystals grow at the same rate (same number of molecules per minute), then my prediction would be the Magnesium Sulfate will make bigger crystal structure, because of the bigger molecules. So I would expect the Epsom Salts to grow much faster - maybe up to 3 times faster. That would be a hypothesis that is testable and measurable.

The jelly like substance is agar and is produced from seaweed. In the laboratory, the agar is placed in a Petri Dish.
Viruses require living cells to replicate and grow. Milk does not contain living cells, so viruses cannot infect or reproduce in milk. Additionally, milk has natural defense mechanisms, such as enzymes and antibodies, that can inhibit the growth of viruses.
To grow viruses in a laboratory setting, you would typically need a nutrient-rich medium that provides the necessary components for viral replication, such as cells or tissue cultures. The exact type of medium would depend on the specific virus being studied. Additionally, specific chemicals and reagents may be required to support viral growth and study.
Viruses can only live in living organisms (viruses themselves are not actually living). They might infect cells in our body, such as throat cells (infection of throat cells causes sore throat).
Interferon
Some alternative substances that can be used for growing viruses include cell cultures (such as Vero cells or MDCK cells), embryonated chicken eggs, or bioreactors. These systems provide a suitable environment for virus replication and propagation outside of agar plates.
no. . . Because parasites and viruses can only grow on living matters... There may be saprophytes and bacteria growing in your food. . . Even parasites and viruses can be there but can not grow. .
Culture
plate assay is the process of observation of colonial physiology and morphology of bacterial cell on agar plate. It helps in differentiation of different species of microbes in many process as in identification of enzyme producing or antibiotic producing organism
viruses are non-living yet they can grow and spread through bodies
One method is a petri dish because the bacteria would grow or not grow in a warm environment. Or a microscope because you could see any activity of the bacteria.
