<h2>Antibiotics</h2>
<p>Antibiotics are another example of a biotechnological advance in medicine. Antibiotics stop or inhibit the <a data-lesson="population-growth-patterns" data-subject="biology" data-tutorial="ecology-overview" href="https://app.ulearngo.com/biology/ecology-overview/population-growth-patterns">growth</a> of certain disease-producing bacteria. These substances were originally found in organisms such as <a data-lesson="kingdom-fungi" data-subject="biology" data-tutorial="classification-introduction" href="https://app.ulearngo.com/biology/classification-introduction/kingdom-fungi">fungi</a> and can now be chemically manufactured. Antibiotics can be administered to patients intravenously as injections, or in the form of tablets, syrups or suspensions.</p>
<p>The first antibiotic, penicillin, was discovered by Alexander Fleming in 1928. He noticed that some bacteria he had left in a petri dish had been killed by naturally occurring penicillium mould.</p>
<p>Since the discovery of penicillin, many other antibiotics have been discovered or developed. Most of those used in medicine have been altered chemically to make them more effective and more safe for humans. </p>

Antibiotics

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.
