During an emergency what you would usually want to do is a so-called threat and hazard analysis - C.
You would do this because you would want to observe and note which is a source of threat for you in a certain emergency situation. You would also to this to observe the possible hazards of doing a certain action/certain actions.
Answer:
The fossils that provide information on the formation of an oxygen-rich atmosphere are the stromatilites from the Precambrian era. These are layered and columnar fossils consisting mainly of cyanobacteria which were the original life form back then. These bacteria took in carbon dioxide and produced oxygen by photosynthesis as early as 2.5 billion years ago (the earth is about 4.5 billion yrs old).
Explanation:
Answer:
According to the given question that without prior knowledge on the prodigiosin synthesis pathway of these Serratia species, and we experience two different color morphs of the species. So, there is given or known preliminary morphological basis we will consider them different two different colonies. These can be identify only after genetically identify or study.
The morphological characterstics of the organism and the genetic identification both are equally important. So Giving any one more importance over other is not logical.
Morphologically we can differentiate the color of the colonies of mutants. The mutant serratia sp. are known for eficient biosynthesis of prodigiosin, Thus on the basis of color characteristics of their colonies when grown on peptone glycerol medium we can identify.
