The Cell Structure and Function

Cells are the structure and basic unit of life, the study of the cell structure and function is called cell biology. Robert Hook was the first biologist to discover cells. All living things are made up of cells. They can be composed of single cells (single cells) or multi-cells (multi-cells). Mycoplasma is the smallest known…

Living Things are the Bedrock of Life

Living Things are the Bedrock of Life

Living things are organisms that possesses or display the characteristics of life or being alive. They include many kinds of organisms, from plants, animals, fungi, and algae that can be easily seen in nature, to numerous small organisms called protozoa, bacteria, and archaea that can only be seen with a microscope can be found in…

Fluids in the Body or Biofluids

Fluids in the Body or Biofluids

In physiology, fluids in the body is the liquid content of the human body. It accounts for a significant percentage of the total composition of the body. Water is a necessary part of maintaining life for many reasons. Most of all cells in the human body consist of the water content in the cytoplasm. Water…

Molecules in Biology, Molecular Biology

Molecules in Biology, Molecular Biology

Molecules in biology refer to any tiny particles, such as charged organic molecules or substances (called biomolecules) that are naturally produced and occurring in organisms, such as proteins, carbohydrates and DNA. In physics and chemistry, the smallest unit of an element or compound is connected together by two or more atoms through reinforced chemical bonds….

ELASTIC PROPERTIES OF SOLID

ELASTIC PROPERTIES OF SOLID

Elastic composition or elasticity is the property of a solid material to restore its original shape and size after being removed from the force that deform it. CONTENT Concept Of Elasticity Hooke’s Law Definition of Elastic Limit Yield point Tensil Stress Tensil Strain Young Modulus     Concept of Elasticity In physics and materials science,…

Electrical Energy and Power

Electrical Energy and Power

Electrical energy is the power of charged particles of atoms to cause action or moving objects. The movement of electrons from one atom to another atom is the cause of generating electrical energy. CONTENT ELECTRICAL ENERGY ELECTRICAL POWER FLEX AND CIRCUIT BREAKER   ELECTRICAL ENERGY Electrical energy is the power of charged particles of atoms…

What is Electric Resistance

What is Electric Resistance

A circuit is a closed path where electrons move to generate current. To answer the question, what is electric resistance of an object, is to know the measure of its opposition to the flow of current. Its reciprocal is conductance, measuring the ease with which current passes. CONTENT DEFINITION RESISTANCE CONDUCTORS AND INSULATORS TYPES OF…

Electric Current and It’s Field

Electric Current and It’s Field

Electric current possess electrical property associated with each point in space when a charge exists in any form. The size and direction of the electric field are represented by the value of E, called electric field strength or electric field strength or simply electric field. CONTENT ELECTRIC CURRENT POTENTIAL DIFFERENCE ELECTROMOTIVE FORCE SOURCES OF ELECTRIC…

Fields at rest; Surface tension in water

Fields at rest; Surface tension in water

Stationary liquids usually take the shape of containers. If the volume of the container is greater than the volume of the liquid placed in it, there will be a free surface at the top of the liquid. The difference between a gas and a liquid is that the gas has neither size nor shape. The…

Nature of Matter II: Molecules

Molecules, are groups of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
