In advanced animals nerve fibres help to coordinate among different parts of our body and in our brain nerve fibres originate which intervene different body parts and help to control them and coordinate and we will focus on cranial nerves and functions of cranial nerves. Cranial Nerve: In our brain and brain stem twelve pairs … Read more
Counter Current Mechanism is a very important mechanism in our kidneys which is essential for formation of urine from the glomerular filtration and we will discuss how counter current is established in our kidneys and how it helps in urine formation. Water is very essential for major cellular metabolism and it helps to maintain constant … Read more

Both forest and wildlife are very important for our healthy environment and we have the responsibility to give them better opportunities for their expansion and help to increase their productivity, and we have to think about how forest and wildlife conservation can be done. From the very beginning we utilise different products of forest and … Read more
We know that in higher animals coordination occurs through the endocrine system and nervous system and in nervous systems nerve impulses need to transfer from a region to the central nervous system and the central nervous system to a specific region. To reach from one region to another region neural information needs some channel through … Read more

We need energy from maintaining cellular activities for growth, development and the regular replacement of damaged old cells by the new cells and to meet the energy we need for food. But food we take does not contain only one type of component, the food we take is actually a mixture of different types of … Read more
Today we are going to discuss a great rule of our environment, competitive exclusion principle and we will discuss the concept of ecological niche. In our environment a number of different organisms grow at a very high rate but their requirements like food, shelter and other resources are limited so it is sure that the … Read more
Hi, now we are going to discuss the nature of a competent cell, its nature and preparation of competent cells and principle of competent cells. What is Competent Cells: In general if we place a living cell in a DNA rich medium then the DNA do not automatically enter into the cells but bacteria show … Read more
