Answer:
The questions does not have any options.
Explanation:
In this case, the possible options are:
- Organisms with more genes will likely have more mutations per generation.
- More selection of mutations can occur in a shorter period of time for bacteria that replicate each twenty minutes than for humans with a (roughly) 20-year generation span.
- Organisms vary in the proportion of DNA that is active and in the percent of loci that have multiple alleles.
- All of the choices are correct- is the correct answer.
Organisms carrying more genes may have more mutations per every generation. Bacteria which replicate by means of asexual reproduction and which are haploid, reproduce after every 20 minutes, and chances of mutation in them occurs more rapidly.
Different organisms vary in the proportion of DNA that is active and in the percent of loci that have multiple alleles.
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
Answer:
beyond that that has be said
Answer: Decarboxylation; amino; higher
Decarboxylation is the removal of a carboxyl group from an amino acid which leaves an amino group causing the pH to go higher
Explanation:
The amino acid, alanine for instance, undergoes decarboxylation (loss of its single carboxyl group) and yields ethyl amine.
The amino group left becomes the main functional group. Thus, it causes the compound to act basic, with a higher pH.
