Dutch researcher Geert Hofstede identified four cultural dimensions by studying data on IBM employees from dozens of countries.
The original theory has four dimensions along which cultural values identified as:
- individualism-collectivism
- uncertainty avoidance
- power distance in social hierarchy
- masculinity-femininity
Hofstede's theory is used to understand the differences in cultures round the globe. He started this model on the basis of dissimilarities in values and beliefs relating work goals. The aim of this model was to determine the dimensions in which cultures vary from each other . It is important because it gives useful information regarding variances between countries' culture, values and beliefs and how to manage such cultural differences".

Osmoreceptors within the hypothalamus detect and increase in plasma osmolarity. This results in a decrease in ADH release from the posterior pituitary, and hence decrease in water permeability of the collecting duct.
<h3>What is osmoregulation?</h3>
Osmoregulation is that the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to take care of the homeostasis of the organism's water content; that is, it maintains the fluid balance and therefore the concentration of electrolytes to keep the body fluids from becoming too diluted or concentrated.
The tendency of water to move into one solution from another by osmosis is osmotic pressure. The upper the osmotic pressure of a solution, the more water tends to maneuver into it.
<h3>Osmoregulation through kidney :</h3>
Pressure must be exerted on the hypertonic side of a selectively permeable membrane to stop diffusion of water by osmosis from the side containing pure water. Although there could also be hourly and daily variations in osmotic balance, an animal is usually in an osmotic steady state over the long term.
Organisms in aquatic and terrestrial environments must maintain the proper concentration of solutes and amount of water in their body fluids; this involves excretion (getting rid of metabolic nitrogen wastes and other substances such as hormones that would be toxic.

The two reasons as to why 12 grader should write NBT is to get into the universities as it is their primary requirement and to apply for scholarship on the basis of one's score.
<h3>
What is NBT and why it is important?</h3>
National benchmark test (NBT), designed to assess the ability of the applicants who wishes to pursue higher education in South African universities.it measures the aptitude and language skills and readiness for university-level education.
Two reasons to write NBT are:
- It is a mandatory test to get into the universities of South Africa. On the basis of the test score, one get admitted into the universities. It helps students to decide which college they will get on their performance basis.
- The test score helps the students to apply for scholarship in college, i.e. if their score is good they can get scholarship.
Therefore, it can be said that it is mandatory for a 12 grader to write NBT and to apply for scholarships.

Laws are necessary to keep society together . For example some protect our general safety, and ensure our rights as citizens against abuses by other people,by organizations and by the government itself. An example of one for our general safety are speed limits and traffic laws exist so that we drive in a safe manner.
