Biology 105 Professor: Brigitte Blackman CRN: 43667 MWF Lecture 9:00-9:50 First Priscilla L. Exploring Life and Science What Is Biology ● Biology is the scientific study of life. ● Life defies a simple, one-sentence definition ● Life is recognized by what living things do Characteristics Shared by Living Organisms ● Organized from the atom to the biosphere ● Materials and energy from the environment ● Reproduction ● Growth and Development ● Maintain a relatively constant internal environment (homeostasis) ● Responds to internal and external stimuli ● Evolutionary history through which organisms change over time. How Are Organism Classified
