Question 1 - Question: What is the necessity of classification of organisms? Answer: Organic evolution has been taking place for 3.5 billion years. It is impossible to study every living organism from an individual level. Therefore, classification is necessary to facilitate easy study of ..

Falling Objects and Acceleration due to Gravity - We know that whenever an object is dropped from a height, it falls towards the Earth. Similarly, when an object is projected vertically upwards, it goes up but after attaining a certain height, it starts falling down. It is the force of gr..

Gregor Mendel, an Austrian monk during 1850s was the first to carry out scientific studies on transmission of characteristics from the parent to the offspring. He selected garden peas as they showed many contrasting traits that were easy to track through the generations. Moreover, these ..

The units of nervous system are specialised cells called the neurons . The general structure of a neuron is as follows: Around the cell body are short sensory projections called the dendrons. The fine branches of dendrons are called the dendrites. These short fibres receive messages..

Since the food is now broken down into the soluble form, the intestinal walls of ileum are able to absorb the nutrients and also water. Due to its large surface area, thin wall lining the cavity and large number of finger-like projections, the villi, maximum absorption takes place in thi..
