The relationship where both the participating entities belong to same entity type is called Recursive relationship

The order of basicity for primary, secondary and tertiary amines are:

Secondary > Primary > Tertiary > NH3

* Amines are basic in nature as they have lone pair of electrons on nitrogen. Therefore, they have a strong tendency to donate this lone pair of electrons to electron acceptors.

* The stability of conjugate acids formed is dependent on the extent of H-bonding,and greater the number of H-atoms on N more stable is the conjugate acid.

* The conjugate acid of primary amine is the most stable with greater number (3) of H-bonds than > Secondary > tertiary. But primary amines are less basic than secondary as the electron density on the N atom is less and lone pair of electrons are not readily available for protonation.

* The two opposing factors i.e. the stability of conjugate acids formed and ease of availability of electrons for Protonation, balance each other in case of secondary amines and it is most basic.

Carbohydrates are also called as saccharides are molecular compounds made from just three elements:

carbon, hydrogen and oxygen.

Carbohydrates are:

* a source of energy for the body e.g. glucose and a store of energy, e.g. starch in plants

* building blocks for polysaccharides (giant carbohydrates), e.g. cellulose in plants and glycogen in the human body

* components of other molecules eg DNA, RNA, glycolipids, glycoproteins, ATP

Types:

1. Monosaccharides (e.g. glucose) and

2. Disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars.

3. Other carbohydrate molecules are very large called Polysaccharides such as starch and cellulose.

It is a marketing strategy in which the sales force is compensated not only for sales they personally generate, but also for the sales of the other salespeople that they recruit. This recruited sales force is reffered to as the participant's 'downline' , and can provide multiple levels of compensation. Other terms used for MLM include pyramid selling, network marketing and refferal marketing. Most commonly, the salespeople are expected to sell products directly to consumers by means of relationship referrals and word-of-mouth marketing.

Associated Press (AP) is world's oldest news agency followed by Reuters and Agence France - Presse.

Hierarchy is a method to structure an establishment employing various levels of administration and a vertical section, or series of command, between higher and lower levels of the organization. Superior levels dominate lower levels of the bureaucracy.
