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>

Why are gymnosperms no longer restricted to moist environments, as are ferns and mosses?
erastovalidia [21]

Gymnosperms are no longer restricted to moist environments, as are ferns and mosses because they have evolved to produce non-flagellated pollens that do not require water or moisture to reach the egg whereas ferns and mosses have flagellated sperm that needs moisture to swim towards the egg.

Another major evolutionary adaption in gymnosperms is the production of seeds instead of spores since seeds contain their own nutrition in the form of endosperm, seeds can travel large distances through wind or animals and can germinate when they find suitable conditions. Seeds can remain dormant for several years whereas spores have a shorter lifespan.

Why are lipids unique when compared to the other macromolecule groups?
Veronika [31]
Lipids are unique because, they are made from one carbon skeleton unlike the other macro molecules groups which are made from smaller building blocks.
With the exception of steroid hormones, lipids are generally hydrophobic. Also lipids are relative small molecules when compare in size with other macromolecules.
