<h2 class="list">Summary</h2>
<p>When you hear the word <em>biology</em>, what do you think of? <strong>Biology</strong> is the <a href="https://app.ulearngo.com/tutorials/biology-101/biology-definition">study of life</a>. When you <a href="https://app.ulearngo.com/tutorials/biology-101/why-study-biology">study biology</a> you will learn about all of the different kinds of living things. You will learn where they live, what they are like, how they depend on each other, and how they behave.</p>
<p>Sometimes it is difficult to tell the difference between living and nonliving things. At times, nonliving things have one or more of the <a href="https://app.ulearngo.com/tutorials/biology-101/characteristics-of-living-things">characteristics of life</a>, but it is necessary to have all of the characteristics of life to be considered living. Things that have all of the characteristics of life are known as <strong>organisms</strong>.</p>
<p>Even though biologists and other scientists study many different types of things, they all use the <a href="https://app.ulearngo.com/tutorials/biology-101/how-science-works">same basic steps</a>. The common steps they use to do research and answer questions are called <strong>scientific methods</strong>. Scientists often <a href="https://app.ulearngo.com/tutorials/biology-101/experimenting-and-forming-theories">figure out questions</a> to ask and answer just by observing the world around them.</p>
<p><a href="https://app.ulearngo.com/tutorials/biology-101/making-biological-drawings">Drawings and diagrams</a> are an essential part of <a data-lesson="introduction-to-cell-communication" data-subject="biology" data-tutorial="cell-communication" href="https://app.ulearngo.com/biology/cell-communication/introduction-to-cell-communication">communication</a> in science, and especially biology. Remember it is not an artwork or sketch! But rather it is a clear representation of what you observe which can be used to interpret what you saw.</p>
<p>Safety is an important factor that scientists think about when carrying out investigations and experiments. It is important to know about dangers that may exist from doing an experiment before you begin it. Anyone doing an experiment has a responsibility to follow <a href="https://app.ulearngo.com/tutorials/biology-101/biology-lab-safety-procedures">safety procedures</a>. </p>

Summary and Main Ideas

Biology studies life and living organisms. Biology can be divided into different sections that cover the morphology, physiology, anatomy, behavior, and so on of living organisms.

Biology

Learn the fundamentals of biology, including the characteristics of living things, scientific method, important principles and tools such as drawing graphs, tables, and biological drawings, and safety procedures in a lab environment.
