5 Important Reasons for low productivity in service industries
1. Usually time-consuming (counseling, teaching)
2. typically concentrated on distinctive personal qualities or desires ( investment advice)
3. frequently an intellectual task carried out by experts (medical diagnosis)
4. Frequently challenging to automate and mechanise (a haircut)
5. evaluating quality is frequently challenging (performance of a law firm)

The antigen's foreignness is the most important determinant of immunogenicity when considering an antigen.
An antigen in immunology is a molecule, molecular structure, foreign particle, pollen grain, etc. that may attach to a particular antibody or T-cell receptor. Antigens within the body may cause an immunological response.
Antigens are outside elements. Normally, the body's defence cells don't react to molecules that belong to it (self antigen). A substance's antigenicity is often correlated with its foreignness . When compared to antigen from other members of the same species, it is less antigenic.
A foreign substance must make up the immunogen. Only substances that are not normally found in the body or exposed to the cells of the particular immune system trigger immune reactions. The immune system will distinguish between "self" and "non-self" in normal circumstances.

Communication during the Renaissance experienced many changes, some of which significantly transformed European culture and lifestyle. The two most obvious contributions were the printing press and the development of secular art.
The printing press allowed books to be more widespread, which increased literacy. It also allowed for the development of newspapers, which informed people of the activities of the government, increasing accountability. Moreover, it made Bibles more widespread, which was influential in the development of new branches of Christianity.
Secular art, particularly in the form of frescoes, also became an important medium of communication. Frescoes often depicted historical figures or events. They also told stories of Greek mythology. This allowed the common citizen to increase his or her general knowledge.
