Our body performs countless functions simultaneously—digesting food, transmitting nerve signals, pumping blood, circulating nutrients, synthesizing proteins, and filtering waste—all of which are made possible by the cell, the basic unit of life. Each cell functions like a miniature factory, equipped with specialized structures known as organelles, each responsible for a specific task. These organelles ensure … Read more
Salivary glands are organs in the mouth that produce saliva, which helps in digestion, keeps the mouth moist, and protects teeth from bacteria. They play a vital role in swallowing, tasting food, and maintaining oral health. Questions about salivary glands often appear in competitive exams like RRB NTPC. Topics include the types of salivary glands, … Read more

Photosynthesis is a remarkable process that sustains life on Earth, and at the heart of this process lies the Calvin Cycle. This cycle, a vital component of photosynthesis, plays a crucial role in transforming carbon dioxide into glucose, which plants use for energy and growth. Let’s explore the Calvin Cycle’s phases, significance, and the complex … Read more
In this article, we explore some fundamental physical properties of liquids and gases, which are collectively known as fluids. The defining characteristic of fluids is their ability to flow, setting them apart from solids in a crucial way. Both liquids and gases are omnipresent in our environment. Earth itself is surrounded by an atmosphere composed … Read more
Electrical power is the result of electrical energy. When an electric current flows through a circuit, it performs work. This work creates power, which can then be stored and used as energy. Electrical power is similar to mechanical power, and they can be converted from one form to another. In this article, we will explore … Read more
An atom is the tiniest part of any element. It contains smaller particles called subatomic particles. The most important of these are electrons, protons, and neutrons. These particles give the atom many of its key properties. The discovery of electrons, protons, and neutrons came from several interesting experiments. In this article, we’ll explore how these … Read more
The proton is one of the three main subatomic particles that make up an atom, along with neutrons and electrons. First discovered in the early 20th century, the proton is a positively charged particle that resides in the nucleus of every atom.
