The kidneys are stimulated to produce renin by a decrease in the blood pressure.

The renin-angiotensin system or RAS regulates blood pressure and fluid balance in the body. When blood volume or sodium levels in the body are low, or blood potassium is high, cells in the kidney release the enzyme, renin. Renin's primary function is therefore to eventually cause an increase in blood pressure, leading to restoration of perfusion pressure in the kidneys.

An agreement between an IT service provider and another part of the same organization. An OLA supports the IT service provider's delivery of services to customers. The OLA defines the goods or services to be provided and the responsibilities of both parties.

* For an example there be an OLA - between the IT service provider and a acquiring department to obtain hardware in discussed times - between the Service Desk and a support group to provide Incident resolution in accepted times.

Vitamin B12 is the only water-soluble vitamin that can be stored in the liver for many years. There are 9 water soluble vitamins.

There are two types of sociological theories:

1. Macro and

2. Micro.

Macro theories focus on the society as a whole and aim at establishing the general characteristics of the society. It is basically looking at the society as a whole and looking at a bigger picture. It aims to answer three basic questions:

1) What holds the societies together?

2) What are the sources of conflict in a society?

3) How do societies change?

There are two branches of macro-sociological theories: consensus and conflict, with the main representative being functionalist and marxist respectively.

Micro theories on the other hand, focus on the individuals who make up the society unlike macro theory which looks at the society as a whole. Micro theories are small scale. Consider it a magnifying glass, when you look through it, you 'zoom' in to the society and see the individuals who have made up that particular society.

Symbolic interactionism is the sociological perspective which is most closely linked to microsociology.

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.
