Look inside the cells of the largest animal or the smallest bacterium and you will find the same things happening. All living things need to be able to process molecules to generate energy, repair damage and grow new cells.Enzymes speed up these chemical reactions. They need specific conditions to work at their best. Understanding the processes of life helps us to treat diseases and improve food production. It allow us to investigate the workings of all life on Earth.
How does a human embryo develop? What makes things with the same genes develop differently? Exploring questions like this is part of the fast-moving world of modern biology.
The Periodic Table is important in chemistry because it helps to make sense of the mass of information about all the elements and their compounds. The table offers a framework that can give meaning to all the known facts about properties and reactions.
Humans have always been interested in how things move and why they move the way they do. Motion is such an obvious part of our everyday lives that we cannot really claim to know very much about the natural world if we cannot explain and predict how objects move.
