Organic Molecules The Chemistry of Life:
Biology is the study of the evolution, diversity and functions of life on Earth. Source What is Biology? Biology is the science of life. Biology is the study of living things. We usually take it for granted that we can tell the difference between something that is alive and something that is not alive; between organic and inorganic things.
But scientists don't take anything for granted. We don't just want to guess. Scientists like to figure things out. So, what is "life"?
How does it "work"? What factors do living things have in common? What are their differences? These are all great questions that Biology, the science of the study of life, sets out to try to answer. What You'll Learn About Biology on This Page By the time you've completed studying this page, you should be able to do the following things: All the answers can be found on this page and you'll get your score straight-away.
Ready to get started? First let's agree a definition of what we mean when we say that something is 'alive'. Charles Darwin's Theory of Evolution and the Scientific Developments That Followed from It Explain All Biology Since Darwin first explained his theory of evolution by natural selection in the nineteenth century, an overwhelming amount of evidence has been accumulated, from palaeontology to genetics, to support it.
Source The Characteristics of Living Things One of the first things we notice when we stop to observe the differences between the things we understand to be alive and other things that aren't, is that living things do stuff.
Rocks, dirt, puddles of water, don't do much. But birds fly, rabbits run, trees grow, people watch TV. You get the idea. So, most scientists agree that living things are defined by what they do.
In order to be thought of as alive, a thing must do most of the following things: All living things need to consume raw materials food, sunlight, water to get the energy and chemicals they require to function. Biologists call this nutrition.
Eating Is Fun and Sociable. It Is Also Essential for Life. One of the things that defines living things, is that they require nutrition in order to gain the energy needed to do stuff.
Have a nice lunch!
basic building blocks of matter and cosmologists studying the structure of the universe on the largest observable scales—have started to converge on a common picture of how the universe expanded from a hot, dense "particle soup" shortly after the Big Bang to form galaxies, stars, and planets. Chapter 1 Cells: The Building Blocks of Life. Practice your knowledge of cell history and the components of cells with this game! Building Blocks in Life Science presents the evidence in an even better fashion in this illustrated worktext. The content of Building Blocks is challenging since author Gary Parker takes the time to explain the scientific evidence for each piece of evidence.
Respiration is the process that breaks up big, carbon-rich molecules to release energy. Sometimes, people get confused about the difference between breathing and respiration.
Breathing is a mechanical action of the muscles and lungs that sucks oxygen containing air into your body. Respiration is the chemical action within the cell that uses the oxygen to make energy.
Sometimes people confuse breathing and respiration. This diver is holding his breath. He has voluntarily stopped breathing. But his cells continue to respire to create the energy he needs to swim. Well, more technically, they excrete.
The processes of nutrition and respiration produce waste material that needs to be gotten rid of.
That's excretion to a biologist.success in college, careers, and life have become commonplace. Specific descriptions of the knowledge and skills needed, however, vary and often remain quite vague.
but few recognize that this coursework is a critical building block for success in school, work, and life, for all students. The Building Blocks of Success 5.

There are four categories of organic molecules: Carbohydrates, lipids, proteins and nucleic acids. When these building blocks are joined together, they form a large molecule (polymer), just as bricks joined.
