Document Summary

Science is a system of generating and organizing knowledge about the universe. It is a system that is testable and undergoing constant revision. Biologists use the scientific process when they study the natural world. A hypothesis is formulated and tested to arrive at a conclusion. Data and observations are collected and analyzed in the formation of conclusions. Hypotheses, theories, or models in science are never proven, they are just supported or rejected. If rejected, then alternative hypotheses need to be developed and tested. The scientific method uses controls to evaluate outcomes from experiments or studies and frequently looks at correlations through the use of independent and dependent variables. The scientific method may yield error (technical or otherwise) and is prone to bias. Biology is the study of living things and their interactions. Successful organisms achieve this in changing environments that may pose complex challenges. The biological solutions may be thought of as adaptations.
