Terms in this set (33)
Order, regulation, growth and development, energy processing, response to environment, reproduction, and evolutionary adaptation are the seven properties common to all life.
The three domains are Bacteria, Archaea, and Eukarya, differing in cell type and genetics.
From smallest to largest: molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere.
New properties that arise at each level of biological organization due to interactions among components.
Observation, question, hypothesis, prediction, experiment, analysis, conclusion.
Includes an independent variable manipulated, a dependent variable measured, and control groups for comparison.
Human-directed breeding to select for desired traits in organisms.
The scientific study of life and living organisms.
All ecosystems on Earth where life exists.
The basic unit of life in all living organisms.
All populations of different species living and interacting in an area.
An experiment that tests a hypothesis by changing one variable while keeping others constant.
Recorded observations and measurements from experiments.
The measured outcome that responds to changes in the independent variable.
