Suppose that you are staining an old culture (more than 24 hrs) of gram-positive organisms. how will the age of the culture affect the staining results? why?

the old bacteria start to loose proteins of their membrane

Explanation:

In a healthy cell, the environmental surrounds it, will no cause lost of proteins, but as the cell get old, by natural means, the proteins  responsible to be stain using the violet color for stain, will be less, so in way you can confuse the result of gram positive into gram negative, even is a positive bacteria but with lack of proteins.  

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

explanation:

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
