Biology Study Guide

Types of Science

• Sciences can be categorized into various branches: Astronomy, Chemistry, Physics, and Biology.
• Natural Science encompasses the study of natural phenomena through observation and experimentation.

Pure vs. Applied Science

• Pure Science aims to expand knowledge without immediate practical applications.
• Applied Science utilizes knowledge gained from pure science to solve real-world problems, often focusing on product or service development.

Scientific Reasoning

• Discovery Science employs inductive reasoning, which involves deriving general principles from specific observations.
• Hypothesis-based Science uses deductive reasoning, starting with a broad understanding to formulate specific, testable hypotheses.

Inductive vs. Deductive Reasoning

• Inductive reasoning generates generalizations based on observations of natural processes.
• Deductive reasoning begins with a known principle to make predictions about specific scenarios.

Experimental Design

• Controlled experiments maintain constant conditions across all parameters to isolate the effect of the independent variable.
• An experimental group tests the independent variable, while a control group serves as a baseline comparison.

Hypothesis and Theories

• A hypothesis must be testable and falsifiable, providing a basis for scientific inquiry.
• Scientific theories are well-supported frameworks that withstand repeated testing and are backed by significant evidence.

Notable Theories in Biology

• The Cell Theory states that all living organisms are composed of one or more cells, which are the basic units of life.
• Other significant concepts include Chromosome Theory, underlying genetic inheritance, and the theory of evolution.

Evidence and Support for Theories

• Theories are validated through a robust body of evidence gathered from multiple experiments and observations, reinforcing their credibility within the scientific community.
