Biology Chapter 1

• The science that deals with life.
• Science is the process used to solve problems & understand natural events.

• Natural events have specific causes.
• Causes for events in nature can be identified.
• Natural events follow general rules & patterns.
• A recurrent natural event has a common cause.
• Different people can observe the same natural events.
• Natural laws hold true regardless of time & place.

• When one event happens as a firect result of a preceding event.
• Ex. Lightning causes Thunder.

• Obervations
• Questions & Exploration
• Forming & Testing Hypothese
• Evaluation of new information.
• Review by peers.

• Logical
• Account for all current information
• Testable
• Make the least possible assumptions

History - because it is not testable so they cannot establish a cause & effect relationship.

Living things can manipulate energy & matter.

• Metabolic Processess
• Generative Processes
• Responsive Processes
• Control
• Unique Structural Organization

Organisms gain & store energy in the chemcial bonds in the ntrients they take in. (When we eat, we turn it into energy)

Organisms grow by the increasing the number of cells & they reproduce.

Organisms react to changes in their enviroment.

Enable organisms to carry out metabolic processes in the right order.

• Biosphere
• Ecosystem
• Communities
• Population
• Organisms

• Organ System - Many organs that perfor a particular function.
• Organ - many tissues that perform a particular function.
• Tissue - Many Cells that perform a particular function.
• Cell - Simplest unit that shows characteristics of life.
• Molecules - Specific arrangements of atoms.
• Atoms - the fundamental units of matter.
