If you're taking Biology or AP Biology in High School or taking first-year biology in college, we're here to help!
In many ways, it's as kaleidoscopic and rich as living organisms themselves.Biologists study life at many scales, from cells to organisms to entire ecosystems. Biology, defined as the scientific study of life, is an incredibly broad and diverse field.In many ways, it's as kaleidoscopic and rich as living organisms themselves. From you, to your dog, to your dinner, to the global ecosystem, all living systems are made out of atoms that obey the basic rules of chemistry. Learn more about this fascinating molecule: its hydrogen bonds, its properties, and why it's a key ingredient for biological systems of all sizes.Biologists study life at many scales, from cells to organisms to entire ecosystems. Here, you can learn about the key properties of atoms, including what particles they contain, how they are organized, and how they form chemical bonds with one another. Plus, brush up on the acid-base chemistry that takes place in water (and learn how it works in your own bloodstream)!Did you know that your body is approximately 18% carbon?
Learn more about carbon and why it makes a great building block for biological molecules.
We'll look at the bonding properties of carbon, the structures of hydrocarbons, different types of isomerism, and some functional groups important in biology.
There's an old saying, "You are what you eat." In some senses, this is literally true!
When we eat food, we take in the large biological molecules found in the food, including carbohydrates, proteins, lipids (such as fats), and nucleic acids (such as DNA), and use them to power our cells and build our bodies.
Dive into the different types of macromolecules, what they are made up of, and how they are built up and broken down.
You, like other living systems, are an amazing energy transformer.
