Answer:

The result will give a smear background of red color or pink , while the  specimen(cell) will turn blue.This is an example of ROMANOWSKY staining.Its main objective is to increase the contrasts for better view.

Explanation:

Histologically,   staining is the process of  adding colors to the speciemen under  focus who can not be discern with naked here to have increase in contrast  to ensure a well defined view.

Eosin is a staining dye that is acidic in nature, while methylene blue is basic,the reaction mixture will separate  the red  color background of  from the blue color of the cell giving a clear contrast .

This technique is mainly used for

1. blood staining and bone marrow staining (biopses)  for disease detection.

2.malaria detection.

3. for Cerecrospinal fluid and lumber puncture  staining,in cytopathology.

<u>Eviences has  shown  that;the mixture  of eosin and methylene blue do not produce the red/blu coloration, but rather the replacement of the methylene blue with AZURE B</u>

Depending on the type of reproduction, offspring can be genetically identical, a clone of their parent, or genetically distinct.
Vlad [161]

• Offspring are genetically identical to parent-asexual reproduction

Fungi reproduce asexually on different ways such as fragmentation, budding, or producing spores(asexual spores, which are produced by one parentand thus, genetically identical to that parent).

• Offspring genetically distinct-sexual reproduction

Sexual reproduction introduces genetic In fungi, there are two ways(two mating types):both mating types are present in the same mycelium (homothallic) or mycelia require two different mycelia (heterothallic).

What would happen if one of the chromosomes in a homologous pair failed to separate from its homologue at the end of metaphase I
Zepler [3.9K]

The correct answer is: daughter cells will have abnormal chromosome numbers and this condition is called aneuploidy.

Nondisjunction is the failure of homologous chromosomes (or sister chromatids) to separate during the process of cell division and consequently lead to aneuploidy. There are three forms of nondisjunction:  

• Nondisjunction in meiosis I (pair of homologous chromosomes unable to separate in meiosis I),  

• Nondisjunction in meiosis I (sister chromatids unable to separate during meiosis II), and

•  Nondisjunction in mitosis (failure of sister chromatids to separate during mitosis)

Is<br> chicken pox like really really bad acne?
RideAnS [48]
Well, no.

Chicken pox are contagious, and acne is not. Also you would be very sick if you had chicken pox.

In appearance, I wouldn't go as far and say that they are alike, or similar as Chicken pox spread across the whole body.

Hope this helps!

The pedigree chart could represent all of the following disorders EXCEPT A) hemophilia B) sickle-cell disease C) red-green color
Thepotemich [5.8K]
The only disorder that cannot be represented using pedigree chart is sickle cell anemia. this because hemophilia, red-green color blindness, and duchenne muscular dystrophy are all X-linked traits. on the other hand sickle cell anemia is an autosomal recessive condition which cannot be represented in the pedigree chart since only sex linked traits are found this chart.
