1.1 INTRODUCTION TO BIOLOGY Key Concepts: What is Biology and how do we study it? What are the characteristics that all living things share? What is the difference between a theory and a law? Vocabulary: Zoology Cytology Ecology Homeostasis Field study Lab study Theory Law

What is Biology? The study of life – Bio means “living,” and logy means “study of.” Biology is divided into many smaller areas that focus on specialized areas of study: Zoology – Study of Animals Genetics – Study of Genes Ecology – Study of Ecosystems Cytology – Study of Cells Botany – Study of Plants

Biological Studies Lab studies – experiments done in a closed environment. Allow scientists to control all variables. Field studies – experiments done in a natural setting. Scientists have little control over variables; however, data may be more accurate. When would a lab study be better? A field study?

CHARACTERISTICS of LIFE All living things have these 7 things in common: CHARACTERISTICS OF LIFE Any Living Thing
