Biology is a life science which studies living organisms and how they interact with each other and their environment. It examines the structure, function, growth, origin, evolution, and distribution of living organisms because life is organized in a hierarchical manner from atoms to molecules and then to organelles, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and biosphere. I find the four major unifying principles formed as the foundation of biology, namely the cell structures, the evolution of living organisms, genetics, meiosis, and homeostasis to be most intriguing. The biological disciplines taught me the significance of responsibility for the protection and the welfare of all living species. The knowledge about the diversity of life forms and their conservation/exploitation is greatly important for our day to day life. The study also taught me the basic idea of the normal organic functions that we consider within the homeostatic parameters. The more I learned about the foundation of biology, the more I was surprised about the mysterious nature of the creatures’ feedback mechanisms. The feedback mechanism is often involved in maintaining homeostasis, with which the body’s systems are stabilized and self-perpetuated. As the result of my biology study at LAVC, the importance of maintaining homeostasis interests me significantly and it connects me deeply with the nursing program I am pursing since nursing work is to assist patients to maintain their homeostasis. Controlling bodily conditions such as blood pressure, body temperature and blood glucose are all related to homeostasis. Nursing knowledge is not only about caring for patients but is also about having the variety of knowledge in terms of the connection between human beings and living organisms affected human beings.
