Complete Explanation of CBSE Notes
What are Quadrilaterals?
Quadrilaterals are one type of polygon which has four sides and four vertices and four angles along with 2 diagonals. Please refer Understanding Quadrilaterals Class 8 Notes for more reviaion notes.
In this type of equations, the expressions which are involved in the formation of the equation are made up of one variable. I.e. the highest power of the variables used in the equations is 1. The solution to this linear equation can be any rational number. This equation may consist expressions which are linear on both sides of the equal to sign. Please refer Linear Equations in One Variable Class 8 Notes for more revision notes.
The numbers which are involved in many mathematical applications such as addition, subtraction and multiplication which are inherently closed with many mathematical processes are called Rational numbers.
Addition and Multiplication are two of the major arithmetic operations involving Rational numbers. Some of the major operations involving these numbers are the Commutative and Associative for rational numbers. Please refer Rational Numbers Class 8 Notes for more revision notes.
Class 8 is a point where the difficulty level of the subjects start hitting the students. Thus, it becomes more imperative that students get their basics right and develop a strong foundation early on. Studying Class 8 Maths Notes is moderately easy provided that students understand the concepts clearly and at the same time practice sums often. If they fail to do so then learning the advanced topics in the upcoming classes will be harder and could lead to inconsistencies.
An environmental issue can be simply defined as any human activity that brings along with it many side effects. One feature of it could bring about development while the other side of the coin could be a detrimental effect. These unfavourable changes often lead to environmental issues that affect the natural balance of the environment. Please refer Environmental Issues Class 12 Notes for more revision notes.
Biodiversity can be defined as the sum of genes, species, and ecosystems that exists at all levels of biological organization.The term Biodiversity was coined by an American sociobiologist Edward Wilson. There are more than 1.5 million species that have been recorded in the world and around 5 to 6 million species on earth waiting to be discovered. Please refer Biodiversity and Conservation Class 12 Notes for more revision notes.
An ecosystem consists of all the living organisms including plants, insects, microorganisms, birds and animals and non-living things including rocks, soil, water and sunlight in the community interacting with each other in a given area of their environment. It is a functional unit of nature and includes both abiotic and biotic components. Please refer Ecosystem Class 12 Notes for more revision notes.
An Organism refers to a contiguous living system that lives in an environment and has the capability to adapt and retain certain structure and behavior. It includes fungus, bacteria, plants, animals, and humans.
Major abiotic factors which lead to variation in the physical and chemical conditions of different habitat are temperature, water, light, and soil. Please refer Organisms and Populations Class 12 Notes for more revision notes.
Biotechnology is defined as the broad area of biology which uses both the technology and the application of living organisms and their components to develop, modify and to produce a useful product for human welfare. The term ‘Biotechnology’ was coined in the year 1919 by an agricultural engineer Karoly Ereky, hence he is called as the father of Biotechnology.
