Mendel’s Dihybrid Cross Experiment

Science > Biology > Genetic Basis of Inheritance > Mendel’s Dihybrid Cross Experiment In this article, we shall study Mendel’s dihybrid cross experiment and its conclusions. The first scientific explanation of inheritance was given by Mendel in 1866. He performed a series of experiments on garden pea in a scientific manner and proposed rules. which are […]

Terminology of Genetics

Science > Biology > Genetic Basis of Inheritance > Terminology of Genetics In this article, we shall study the terminology of Genetics and understand the concept of alleles. Heredity: The transmission of characters from one generation to the next, that is from parents to offsprings (progeny) is known as heredity. These hereditary characters are present on […]

Introduction to Genetics

Science > Biology > Genetic Basis of Inheritance > Introduction to Genetics In this article, we shall study the history of the science of genetics and the contribution of Gregor Mendel to Genetics. History of Genetics From the earliest recorded history, ancient civilizations observed patterns in reproduction. Animals produce offspring of the same species, children […]

Elastic and Inelastic Collision

Science > Physics > Force >Elastic and Inelastic Collision When two bodies moving along a straight line collide with each other the collision is called the head-on collision. In a head-on collision, the initial and the final velocities are along the same straight line. Elastic Collision: The collision in which the total kinetic energy, as […]

Moment of Force

Science > Physics > Force > Moment of Force In this article, we shall study the concept of moment of force, its characteristics, and applications in everyday use. Rigid Body: A rigid body is one whose geometric shape and size remains unchanged under the action of an external force. In the rigid body, the distance […]

Couple

Science > Physics > Force > Couple In this article, we shall study the concept of a couple, its characteristics, and applications. Parallel Forces: Forces which are not concurrent and their lines of action are not the same and parallel to each other then the forces are called parallel forces. Example: Children sitting on a […]

Law of Conservation of Momentum

Science > Physics > Force > Law of Conservation of Momentum In this article, we shall study the law of conservation of momentum and its proof. Statement: When the resultant external force acting on a system is zero, the total linear momentum of the system is constant. OR When no external force acts on a […]

Physical Equilibrium

Science > Chemistry > Chemical Equilibrium > Physical Equilibrium There are two types of equilibrium: a) physical equilibrium and b) chemical equilibrium. In this article, we shall study physical equilibrium. State of Equilibrium: In many chemical reactions, it is observed that they do not proceed to completion when they are carried out in a closed […]
