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
B.
Humans are also part of ecosystems and if they cease to exist, human well being will be affected.
Thymine has a methyl group and is better suited for the storage property of the DNA molecule as it is far more stable compared to Uracil.
RNA contain Uracil instead of thymine so as to make differentiation of RNA molecule from DNA molecules easier.
Answer:
In this experiment the mass must be measured first because to determine volume water displacement is what is being measured. ... The reason for this is some solids will float on the water. Therefore the object's density is less dense than the water.
