Introduction Human life is continuously exposed to millions of microorganisms—bacteria, viruses, fungi, and parasites—that can cause infections and diseases. Despite this, we survive and thrive because of a remarkable defense network called the immune system. The immune system is the body’s security force, identifying and neutralizing harmful invaders while remembering past infections to protect against…

The human body is a masterpiece of natural engineering. Beneath our skin lies a network of organs, tissues, and cells working in harmony to keep us alive. This incredible organization is divided into body systems—groups of organs and structures that perform specific functions. From pumping blood and transporting oxygen to digesting food and fighting infections,…

Introduction One of the most fascinating areas of life science is genetics and heredity. These two concepts explain how living organisms inherit characteristics from their parents and how these traits are passed down through generations. Genetics is the scientific study of genes, DNA, and the mechanisms that control inheritance, while heredity refers to the actual…

Among the greatest scientific discoveries of the 20th century is the identification of DNA (Deoxyribonucleic Acid) as the molecule of heredity. DNA is the blueprint of life, containing the instructions that determine the growth, development, functioning, and reproduction of all living organisms. From the shape of your eyes to your resistance against certain diseases, DNA…

Introduction Life is a fascinating and complex phenomenon. From the tiniest bacteria to the tallest trees and the most advanced animals, all living beings are made up of one common building block – the cell. The cell is the fundamental unit of life, often described as the “smallest living factory” because it performs all the…

Life surrounds us in countless forms, from the tiniest bacteria thriving in extreme environments to complex animals like humans capable of thought, language, and culture. The study of this vast diversity of living organisms, their processes, and their interactions with each other and their environments is known as Life Science. It is one of the…
