The question seem to be incomplete but I found the complete question which is:
If you are performing this test on an unknown organism, why is it a good idea to run simultaneous tests on known phenylalanine-positive and phenylalanine-negative organisms?

Here is the Answer:

Inoculation of a positive control and success from it includes certainty to negative outcomes on an unknown organism. That is, you know the test is working effectively, so the negative outcome is most likely precise. Without the positive control, there is dependably a component of uncertainty whether the negative outcome is a genuine negative or a false negative. performing the test on a known phenlalanine-negative organism is valuable in that it exhibits what a negative outcome looks like.

Identify the phases of Meiosis II described below.
Annette [7]

1. The lining up of chromosomes by the spindle fibers takes place at metaphase II phase. It is the second stage of meiosis II, the spindle draws the chromosomes towards the metaphase plate.  

2. The formation of the nuclear envelope around each set of DNA takes place in telophase II. Along with the formation of the nuclear envelope, the process of cytokinesis also takes place in telophase II, producing four daughter cells, each comprising a haploid set of chromosomes.  

3. The sister chromatids are pulled apart in anaphase II stage. In this phase, the sister chromatids are migrated towards the opposite poles of the cell with the help of protein fibers.  

4. The centromeres are moved towards the poles of the cell at prophase II stage.
