The main branches of science (also referred to as "sciences"‚ "scientific fields"‚ or "scientific disciplines") are commonly divided into two major groups: social sciences‚ which study human behavior and societies‚ and natural sciences‚ which study natural phenomena (including fundamental forces and biological life). These groupings are empirical sciences‚ which means the knowledge must be based on observable phenomena and be capable of being tested for its validity by other researchers working under

Gas exchange is a biological process that is essential for the survival of an organism. The purpose of this process is to obtain oxygen from the environment (which is necessary for cellular respiration‚ and to dispose of CO2‚ a bi product of respiration. An efficient gas exchange system has 3 requirements. It must have a large surface area over which the gases can diffuse. A large surface area maximises the amount of area available for the gases to exchange. It must also be moist. Oxygen must first

Application on Normative Ethical Theories Is organ donation to a family member a moral obligation? Is it possible to love ones child well‚ yet dent them the very organ that one is physically capable of giving them?
