Biology Study Guide

Study Notes

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.
