The term "IMViC" is an acronym for each of these tests. "I" is for indole test; "M" is for methyl red test; "V" is for Voges-Proskauer test, and "C" is for citrate test. The lower case "i" is merely for "in" as the Citrate test requires coliform samples to be placed "in Citrate". Triple sugar iron test (TSI), Urease Test and Malonate Test are also included in this test.
For each of the tests, different reagents are added to the species are inoculated and tested.
For Salmonella sp. the IMViC Test result is:
Indole - negative
Methyl red - Positive
Voges-Proskauer - negative
Citrate - positive

9. The structure affects its function because in its inner membrane allows for more surface area and that increases the amount of ATP that is produced by it. <span>

The virus' DNA becomes a part of the host cell's DNA, and every time the host cell copies and divides, it also copies viral DNA. The viral DNA may remain inactive (a provirus) for a long time, but it can become active when it frees itself from the host's chromosome, which triggers the lytic cycle.
I forget which one is the virus' DNA
yes, Muscularis mucosa - The stomach and small intestine's mucosa are pulled into undulating folds by a thin layer of smooth muscle that is constantly tensed. The surface area that is available for digestion and absorption is significantly increased by these folds.
The submucosa is located directly beneath the mucosa, as its name suggests. It joins the underlying muscularis to the overlaying mucosa by way of a large layer of dense connective tissue. It has blood and lymphatic vessels (which carry nutrients that have been absorbed), as well as a few submucosal glands that secrete digestive juices. Additionally, it functions as a passageway for the submucosal plexus, a densely branched network of nerves.
These layers compress to encourage mechanical digestion, expose more of the food to the chemicals that aid in digestion, and transport the food along the canal.

Great question! Let me first talk about how sedimentary rocks are formed. Sedimentary rocks are formed when when existing rocks are broken down in sediment. Now, let me explain what they are. Sedimentary rocks are rocks that have been weathered into rock fragments or pieces.
