Ethics in Synthetic Biology Have you ever wondered what healthcare would be like if ethics were not governing the crucial decisions regarding the lives of people? If so‚ you possibly understand how important ethics is in general and if not‚ imagine a world where the best interest that was not considered and the decision that may inflict harm was used as the best decision. Ethics is a very important factor in everyday decisions‚ especially referring to the well being of others. Special fields in science

Biology 101 : A Crash Course The school bell rings on the first day of school. Your students start to trickle into the class little by little. They see the various microscopes and dissecting equipment‚ and their eyes go wide. Biology is a very fun and interactive subject for students‚ which makes it all the more exciting to be able to teach it. Ever since I took sophomore biology in high school I haven’t been able to stop thinking about it. My teacher just always seemed like he was having as much

Biology is the study of life. Without biology‚ we would have no idea about an organism’s makeup‚ or the most basic unit of life‚ a cell. It plays a very important role in our lives. It teaches us how our body functions and how we can take care of it. You have a better overall view when you know all areas of academic study. Likewise‚ you get to know the scientific method. Biology influences me in many ways. Biology influences me by teaching me why to take care of the environment‚ why I am to take

and their abundance‚ leading to three questions ecologists often ask about organisms : Where do they live? Why do they live where they do? And how many are there? Because of it’s great scope‚ ecology is an enormously complex and exciting area of biology‚ as well as one of critical importance. Ecology reveals the richness of the biosphere—the entire portion of Earth inhabited by life—and can provide the basic understanding that will help us conserve and sustain that richness‚ now threatened more than
