Is Mcdonalds primary secondary or tertiary?
McDonald's is a primary, secondary and tertiary sector. The primary sector is responsible for the raw materials such as farming animal. The final production is the tertiary sector, this is the service that McDonald's provides such as advertising or selling food to the consumers.
Primary, Secondary, and Tertiary Literature. Sources of information are often considered primary, secondary, or tertiary depending on their originality and proximity of when it was created. Consider if it is an original work, or whether it evaluates or comments on the works of others.
- Indexes, bibliographies, concordances, and databases may not provide much textual information, but as aggregates of primary and secondary sources, they are often considered tertiary sources. Almanacs, travel guides, field guides, and timelines are also examples of tertiary sources.
- Examples of Primary Sources. Some examples of primary source formats include: archives and manuscript material. photographs, audio recordings, video recordings, films.
- Tertiary Sources. These are sources that index, abstract, organize, compile, or digest other sources. Some reference materials and textbooks are considered tertiary sources when their chief purpose is to list, summarize or simply repackage ideas or other information.
These sectors can be viewed as a continuum, starting with the primary sector, which is the part of the economy generated by extracting raw materials directly from the earth for consumption or sale; moving next into the secondary sector, which is the part of the economy that transforms the raw materials into goods for
- Secondary industries are those that take the raw materials produced by the primary sector and process them into manufactured goods and products. Examples of secondary industries include heavy manufacturing, light manufacturing, food processing, oil refining and energy production.
- The term tertiary economic activity typically refers to the service sector; the primary economic activity is the production & sale of raw goods; the secondary economic activity refers to the purchase and sale of finished goods (consumer durable or non-durable).
- The tertiary sector or service sector is the third of the three economic sectors of the three-sector theory. The others are the secondary sector (approximately the same as manufacturing), and the primary sector (raw materials). The service sector consists of the production of services instead of end products.
A primary alcohol is an alcohol which has the hydroxyl group connected to a primary carbon atom. It can also be defined as a molecule containing a “–CH2OH” group. In contrast, a secondary alcohol has a formula “–CHROH” and a tertiary alcohol has a formula “–CR2OH”, where “R” indicates a carbon-containing group.
- Primary = a hydrogen on a carbon attached to only ONE other carbon. Secondary = a hydrogen on a carbon attached to only TWO other carbons. Tertiary = a hydrogen on a carbon attached to THREE other carbons.
- A secondary alcohol is a compound in which a hydroxy group, ?OH, is attached to a saturated carbon atom which has two other carbon atoms attached to it. Stars.
- Both examples show that oxidation leads to an increase in the oxygen to hydrogen ratio. Tertiary alcohols are not easily oxidised because, unlike primary and secondary alcohols, they do not have a hydrogen atom attached to the same carbon atom as the hydroxyl group.
