Accuracy v. Precision
• Precision• Def: Achieves same
result multiple times
• Accuracy• Closest to actual
value/condition
Range of Acceptable Measurements• An observed value is
considered “accurate” if it falls within the range of acceptable measurements
• Ranges vary based on the measurement device
• RANGE IS DETERMINED AS THE MEASURED VALUE + and – HALF THE SMALLEST INCREMENT ON THE MEASURING DEVICE
WHAT IS LIFE?
WHAT ARE THE CHARACTERISTICS OF LIVING ORGANISMS?
Characteristics of Individual Living Organisms
• Living organisms are cellular• Living organisms reproduce on some level• Living organisms are based on a universal genetic
code• Living organisms grow and develop• Living organisms have a metabolism (i.e. use materials
and energy and produce waste)• Living organisms respond to their external environment• Living organisms maintain a stable internal
environment
ORGANIZATION
• All life is organized on multiple levels– Organ Systems– Organs– Tissues
• The smallest level of organization is the cell
UNIVERSAL GENETIC CODE
Nucleic Acids
• DNA• RNA• “Language” used for the
assembly of proteins
ENERGY FLOW
• Since energy cannot be created or destroyed, organisms change the form of energy on multiple levels
• An organisms’ energy needs and means for changing energy is its metabolism
HOMEOSTASIS
• Organisms try to maintain the “same state” for many of its internal systems– Body Temperature– Water Balance– O2/CO2 Balance
• Loss of homeostasis = death/illness
RESPONSE TO ENVIRONMENT
• When environmental conditions change, organisms must respond to survive and maintain internal homeostasis
• Behavior
REPRODUCTION
• Organisms must have the capacity for either sexual or asexual reproduction on some level of organization
GROWTH
• Living organisms increase through the addition of protein and/or the addition of additional cells to their structure
DEVELOPMENT
• Living organisms must change their forms or functions over time to best suit the needs of the organism at that time
