The Oxidation-Fermentation Test is used to differentiate bacteria built on their capability to oxidize or ferment specific sugars.
Once microbes are inoculated,-One tube is sealed with a layer of sterile mineral oil to promote anaerobic growth and fermentation.-The other tube is left unsealed to allow aerobic growth and oxidation.
Organisms able to ferment the carbohydrate or ferment and oxidize the carbohydrate will turn the sealed and unsealed yellow throughout.
Organisms able only to oxidize the sugar will turn the unsealed yellow medium and leave the sealed medium green or blue.
Fragile fermenters will convert both tubes slightly yellow at the top.
Organisms not able to metabolize the sugar will either produce no color change or will turn the medium blue due to alkaline products from amino acids degradation.
Since Pair #1 showed complete yellowing for sealed and unsealed, these Organisms able to ferment the carbohydrate or ferment and oxidize the carbohydrate. So our interpretation will be that the organism has: Oxidation and fermentation OR fermentation only.
For tubes #2 and #3, the sealed tubes were green throughout suggests that they need oxygen for aerobic growth, and the fact that their unsealed tubes showed light yellowing is evidence for oxidation. Sealed - Green and Unseal - Yellow. Our interpretation for these pairs of tubes would be : Oxidation
Tube 1 can be either Oxidation and fermentation OR fermentation only. So reliability of this needs to be confirmed more with additional testing.
Tubes 2 and 3 are most reliable because they can only be oxidation only and no fermentation.
If they are both albino there is no chance for them to have any other skin color because it is not in their genes. The phenotype gene is always going to be albino.
Among the tasks in coping with life-threatening illness described by Kenneth Doka, the chronic phase is characterized by "living with the disease".
Kenneth Doka (1995–96) divides the process of dying into three phases, namely the acute, the chronic, and the terminal phases of dying, during which the individual initially is given the diagnosis, then lives with the disease and ultimately surrenders to death.
This phase can be quite long and the supporters may become comfortable in their caregiving role and adjust to the notion of death. This is an important adaptation since a great deal of the care for the terminally ill is given by the family members.
Doka (1998) notes that this phase "is often a period of continued stress, punctuated by points of crisis".

Answer: 23 chromosomes
In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23.
