Study Notes

Introduction to Biology Today

Biology is the scientific study of life
Taxonomy is the science of naming and classifying organisms
The Mars rover aims to search for signs of life on Mars

Biology All Around Us

Most people have an inherent interest in life
Biology is vital in the understanding of health, fitness, and the importance of nature
Chapter topics vary but include medical aspects, society aspects, biological importance, and relationships within the subject of biology

The Scientific Study of Life

Biology is the scientific study of life
Science is an approach to understanding the natural world grounded in inquiry, which is the search for information, explanations, and answers to questions
Two principal forms are discovery science and hypothesis-driven science
Data (recorded observations) are the foundation of scientific inquiry.
Science distinguishes itself from supernatural beliefs as data must be verifiable.

The Process of Science

Biology is the scientific study of life
Scientific studies involve observations and measurements
These observations lead to questions and hypotheses
Hypotheses are tentative explanations that require testing
Predictions are developed based on the hypothesis, and testing follows predictably
Experiments are conducted to test the hypothesis and predictions
Experiments can lead to revised hypotheses or additional questions
Scientists often incorporate discovery science and hypothesis-driven science in conjunction with one another

Theories in Science

Facts, while important, are not the primary objective of science
Theories are broad statements encompassing a wide range of observations, supported by evidence, and capable of generating new testable hypotheses
A theory emerges when a large amount of evidence supports a particular explanation
Scientific theories continually revise and develop as more data emerges.

The Nature of Life

Biology is the scientific study of life.
There's no single, concise definition of life.
Living things exhibit certain characteristics, such as: order, reproduction, growth, adaptation, and evolution.

Major Themes in Biology

Evolution: living things evolve (change) from ancestral species over time
Structural/functional relationship: Structure relates to function, and vice-versa
Information flow: information is passed from one cell to another, from one organism to another
Energy Transformations: Organisms receive, transfer, and use energy
Interconnections: living things are interconnected within biological systems
