Question

5. is the unique identify of each cell in a worksheet.​

Answer 1

Answer:

Understanding cells

Columns are identified by letters (A, B, C), while rows are identified by numbers (1, 2, 3). Each cell has its own name—or cell address—based on its column and row.

For most cells there is nothing like a unique identification but an identification of specification. Or even only on the level of cell type.

Example red blood cells. They are all about the same. No, that is not correct, after servicing about four months they get separated and taken out of duty and become digested in the liver. How are they picked? On wear marks on their surface which act as identifiers of their age in addition to the cellular markers it's a red blood cell. Another thing abou them: If you add some from a stranger, chances are, the newcomers are not well accepted. That is for a specific marker on them that is always checked, called blood group. And there is more. But not a unique cell identifier for them.

In B cells again you have not a unique cell identifier but maybe you come close to it. There is at a given time maybe only a very small number of B cells specified in the production of one specific (each is specific) antibody reactive just with this one antigen that at the moment is not in sight. So as long as there is nothing to do these cells go dormant, maybe for the rest of your life, as long as this antigen does not show up. But if it shows up eventually, they immediately start production. They turn power on and divide and produce that one kind of an antibody. So they are called and evoken, chosen from all others on grounds of that antigen or only the antigenic epitope their antibody's epitope is fitting to, which they demonstrate as a "unique" marker for their ability to produce such on their outside surface.

Another story goes about nerve cells. A lot of details are known about them but not enough to really understand and describe the full story on a cellular and molecular level. At least it must be known in the system where to look for a specific answer to a special problem. Where did I store that info? These cells should be adressable somehow and the system does it by very individual linking connections.
