No. Epithelium is a protective layer of cells typically covering the outside of an organ or the lining of the wall of a cavity in the body. All body cells need organic molecules to provide energy for building proteins, lipids, and other organic molecules.
The class of large organic molecules that include polymers is proteins, nucleic acids, and carbohydrates. Lipids are the fourth major class of large organic molecules, but they are not polymers.
pyrimidines
Well they usually are plant cells. In my science class we learned all about that plant and animal stuff. If you have anymore questions about cells and genetics, just ask! :)
Uracil is found in the class of organic molecules known as nucleotides, which are the building blocks of nucleic acids like RNA. Specifically, uracil is a pyrimidine base that pairs with adenine during RNA synthesis. It is one of the four primary bases in RNA, alongside adenine, guanine, and cytosine.
Because they are carbon-based and deal with organic chemistry.

Yes, antigen presenting cells have major histocompatibility complex class I molecules.
Lipids are the class of organic compounds that store energy as fat in living organisms. They consist of molecules such as fats, oils, and waxes that are insoluble in water and contain long hydrocarbon chains. Stored fats can be broken down to provide energy when needed by cells.
pyrimidines
Cells use nucleic acids, specifically DNA and RNA, to store genetic information. These molecules are composed of nucleotides which contain the genetic code.
pyrimidines
Purines
specially sequenced polypeptides or most important are oligosacchrides
Presented by APCs as MHC-exogenous peptide complex
MHC proteins express antigens on a cell surface for T cells to identify whether the antigens presented are self or foreign. There are two classes MHC I and MHC II. They differ in which cells they require to activate depending on the pathogen present.
An organic compound is any member of a large class of chemical compounds whose molecules contain carbon.ribonucleic acid contains carbon.
