Solution Solution is homogeneous mixture of two or more substances. It is composed two components which are solute and solvent. Solute is present in less quantity whereas, solvent is present is large quantity in solution. For example, sugar solution[liquid solution], mixture of metals i.e. alloys [solid solution], mixture of air [i.e. gaseous solution] Amount of […]

Heredity in Humans
Heredity is passing of traits from parents to child. Sometimes child looks similar to parents, it is because child inherits traits like eyes, complexion, color of hairs. Mendel’s contribution in heredity Traits in child are influenced by the DNA of father as well as DNA of mother. Moreover, with each DNA there are two version […]
What is Gravitation?
Presence of gravitation or gravitational force was first brought up by Sir Isaac Newton. Story of falling of apple on Newton’s head is very much familiar. Apple fell on head of newton, on basis of this observation, he carried out experiments. Moreover, the experiments revealed the existence of gravitational force on basis of which universal […]
Embryo Development
Male and female gametes undergo fertilisation to form zygote which is unicellular organism. This cell or zygote develops further to form an embryo which eventually forms a baby. Development of Embryo in human beings In human beings, after the formation of zygote, the zygote undergoes repetitive cell division thereby increasing number of cells. When number […]
What is Animal Husbandry?
Animal husbandry or animal farming is branch of agriculture. Particularly, animal husbandry deals with management of animals i.e. animals are raised for acquiring essential products like milk, meat and eggs. Therefore, animal husbandry includes farming of animals like cow, goat, buffalo, fish, sheep, poultry, etc. More specifically, animal husbandry is divided into cattle farming, poultry […]
Rate of motion: Speed, Velocity and Acceleration
Rate of motion helps to understand how body changes its speed with respect to time. Speed, velocity and acceleration describes rate of motion. Speed Rate of motion can be defined in the form of speed. Speed is distance travelled per unit time. SI unit of speed is m/s. In other units this rate of motion […]
Kingdom Plantae
In 1959, R H Whittaker, classified living organisms into five categories that are Monera, Protista, Fungi, Plantae and Animalia. In particular, Kingdom Plantae, is further classified into 5 divisions which are Thallophyta, Bryophyta, Pteridophyta, Gymnosperms and Angiosperms. Thallophyta Thallophytes are the simplest plants under kingdom plantae. Thallophytes do not contain different parts like stem, leaves, […]
Soil
Soil is an important natural resource as it provides growth of plants, provides food and shelter and many more. If soil is in rock form, it becomes difficult to use it for different purposes. A natural process of weathering takes place to convert rocks into fine particles called soil. Process of Soil Formation Sun Due […]
Phylum Vertebrata
Kingdom Animalia consist of phylum Porifera, Coelenterata, Platyhelminthes, Nematoda, Annelida, Arthropoda, Mollusca, Echinodermata, Protochordata and Vertebrata. Phylum vertebrata is divided into five classes Pisces, Amphibia, Reptilia, Aves and Mammalia. Pisces Class pisces contains all fishes. Pisces are aquatic animals having streamlined body and muscular tail. Skin is covered with scales and heart of pisces are […]
Ohm’s Law – Relation between Resistance, Potential Difference and Current
Ohm’s law determines the relation between the potential difference and the flow of current. Therefore, Ohm’s law states that, “ At constant temperature potential difference(V) is directly proportional to current (I)” V∝ I Verification of Ohm’s Law At constant temperature, if we plot a graph of current versus potential difference, a straight line graph passing […]
