What Is Biology The science of biology is, broadly speaking , the study of living things.It draws on chemistry and physics for its foundation and applies these basic physical laws to living things. Because there are many kinds of living things, there are many special areas of study in biology. Practical biology—like medicine, crop science, plant breeding, and wildlife management –is balanced by more theoretical biology—such as medical microbiological physiology, photosynthetic biochemistry, plant taxonomy, and animal behavior (ethology). There is also just plain fun biology like insect collecting and bird watching. Specifically, biology is a science that deals with living things and how they interact with all of the things around them. Biology was defined as the science that deals with livings. But what does it mean to be alive? You would think that a biology textbook could answer this question very easily. However, this question is more than just a theoretical one, since it has become necessary in recent years to construct some legal definitions of what life is and especially when it begins and ends. The legal definition of death is important since it may determine whether or not a person will receive life insurance benefits or if body parts may be used in transplants. In case of heart transplants, the person donating the heart may be legally ― dead ‖ , but the heart certainly isn’t since it can be removed while it still has ―life‖ . In other words ,there are different kinds of death. There is the death of the whole living unit and the death of each cell within the living unit. A person actually ―dies‖ before every cell has died. Death ,then, is the absence of life, but th...
