Bread is one of the oldest and most widely consumed foods in the world. Made from flour and water, and usually baked, it comes in many forms, from simple flatbreads to more complex loaves. Bread has been a dietary staple for thousands of years, and its variety and versatility have made it an essential part of cuisines worldwide. History of Bread The history of bread dates back to ancient times. Evidence of bread-making dates back at least 14,000 years, based on archaeological findings of ancient grain-based foods. Early bread was likely unleavened, meaning it didn’t rise during baking. As time passed, people began discovering leavening agents like yeast, which made bread lighter and fluffier. In ancient Egypt, around 4,000 years ago, bakers mastered the process of making leavened bread, which is still a key element in bread-making today. Over the centuries, bread-making spread to other cultures, and its popularity grew. Basic Ingredients of Bread Flour : The most essential ingredient ...

 An egg is a small, oval-shaped reproductive body produced by female animals, particularly birds, that is commonly consumed by humans as a food item. Among the most commonly eaten eggs are those of chickens, although eggs from other animals like ducks, quails, and even fish are also consumed in different parts of the world. Eggs are rich in nutrients and provide a variety of essential vitamins and minerals, making them a staple food in many cultures. Components of an Egg An egg typically consists of three main parts: Shell : The shell is the outer protective covering of the egg. It is made primarily of calcium carbonate and provides a barrier to protect the contents inside. The shell is typically white or brown, with the color depending on the breed of the bird. The shell is also porous, allowing gases to pass in and out, which helps preserve the egg. Egg White (Albumen) : The egg white is the clear, viscous liquid that surrounds the egg yolk. It is made up mostly of water and pro...

It is one of the most significant inventions in modern history, allowing people to travel long distances quickly and efficiently. Airplanes are used for various purposes, including commercial air travel, cargo transportation, military operations, and private flights. What is an Airplane? An airplane is a vehicle that uses wings to generate lift and a propulsion system (usually an engine or turbine) to move through the air. The wings are designed to create lift as air flows over and under them, allowing the plane to stay airborne. Airplanes are typically designed with a fuselage to house passengers and cargo, and they are controlled by a pilot using a system of controls, including an yoke (steering wheel), pedals, and throttle. Types of Airplanes Commercial Airplanes : These airplanes are used for transporting passengers and cargo over long distances. Commercial airplanes are typically large and can carry...
