Prostaglandins are synthesized by many tissues in the body when they are damaged or infected in order to deal with such injuries/infections. They are hormone-like compounds involved in pain and inflammation.

If you want to grow up a large quantity of streptomycin-resistant E. coli, you would require to pick a colony of the bacteria from the streptomycin-positive plate and allow to grow it on a streptomycin positive plate.
<h3>What is E. coli?</h3>
E. coli may be defined as a type of bacterium that is commonly present in the intestinal regions of humans and other animals, some strains of this bacterium can significantly cause severe food poisoning.
The strain of streptomycin-positive is those population of E. Coli which is significantly streptomycin resistant, while the negative strain has the opposite effect.
That's why if you want to grow up a large quantity of streptomycin-resistant, you must remarkably require to pick only a positive strain of streptomycin for E.Coli bacterium.
Therefore, if you want to grow up a large quantity of streptomycin-resistant E. coli, you would require to pick a colony of the bacteria from the streptomycin-positive plate and allow to grow it on a streptomycin-positive plate.
