Description
Biology is the science of life, and this course is designed to make that science accessible, exciting, and relevant to your everyday world. Whether you are fulfilling a general education requirement, preparing for a career in health or environmental fields, or simply curious about how living things work, this course will guide you through the essential principles that explain life on Earth. You don't need a strong science background to succeed here-just curiosity and a willingness to explore.We begin by asking the most fundamental question: what is life? From there, we build a foundation by examining the nature of science itself-how scientists ask questions, design experiments, and interpret evidence. You'll learn how biology connects to chemistry, because understanding atoms, molecules, and chemical reactions is key to grasping how living systems function. We'll explore water, pH, and the molecules of life-carbohydrates, lipids, proteins, and nucleic acids-so you can see how these building blocks come together to form cells.Cells are the basic units of life, and you'll discover their structure, function, and diversity. We'll compare prokaryotic and eukaryotic cells, study membranes and transport processes, and understand how cells maintain homeostasis. From there, we dive into energy-how organisms capture, store, and use it. You'll learn about ATP, enzymes, cellular respiration, and photosynthesis, and see how these processes power life on Earth.Genetics is another cornerstone of biology, and this course makes it clear and approachable. You'll explore DNA structure and replication, transcription and translation, and the central dogma of molecular biology. We'll cover Mendelian genetics, non-Mendelian inheritance, and chromosomal patterns, helping you understand how traits are passed from one generation to the next. You'll also learn about cell division-mitosis and meiosis-and why these processes are essential for growth, reproduction, and genetic diversity.As we move forward, we'll broaden the lens to evolution and the history of life. You'll examine natural selection, genetic drift, speciation, and other mechanisms that shape biodiversity. We'll look at the fossil record, phylogenetic trees, and the incredible story of life's development over billions of years. Along the way, you'll meet single-celled organisms, plants, fungi, and viruses, and discover how they fit into the web of life. We'll also touch on biotechnology, including PCR, genome sequencing, and mRNA vaccines, showing you how biology impacts medicine and technology today.This course is more than memorizing facts-it's about understanding connections. By the end, you'll see how molecules, cells, organisms, and ecosystems are linked in a dynamic system that sustains life. You'll gain the ability to interpret scientific information, think critically about biological issues, and appreciate the relevance of biology to health, environment, and society. Whether you're a student, a professional, or a lifelong learner, this course will give you a solid foundation in biology and inspire you to keep exploring the science of life.What You'll LearnExplain the fundamental principles of biology and the nature of life.Understand cell structure, function, and energy flow.Describe DNA structure, replication, and protein synthesis.Apply concepts of genetics, inheritance, and evolution.Interpret scientific data and think critically about biological issues.Explore biodiversity, ecosystems, and the history of life.Understand biotechnology applications like PCR and genome sequencing.Materials and videos provided under this course are on a Creative Commons (CC) License.
