Biological Organization
Smallest unit of an element
Atom
Species have multiple generations because they are able to do this
Reproduce
This is the factor in the experiment that is being changed
Independent Variable
This is why salt dissolves in water
Water is a solvent
Has a pH of 7
What is pure water/neutral
A group of cells with a common structure and function
Tissue
All chemical reactions in a cell
Metabolism
This is the group that receives no treatment, standard treatment, or a placebo
Control group
This is why water domes when slowly poured into a container
Surface Tension
Tomato juice is an example of this
Acid
Composed of several organs working together
Organ System
When bacteria "swim" toward light, they are doing this.
Responding to a stimuli
In your experiment you must carefully document this so others can repeat the experiment in the future
Procedure, steps in the experiment and data recording
This is the type of bond between Oxygen and Hydrogen in the H2O molecule
Polar Bond - a type of covalent bond
Milk of Magnesia is an example of this
Base
Organisms of the same species in a particular area
Population
Ability to maintain a stable internal environment even when external environments change
Homeostasis
List the steps of the scientific method

Why is ice a good insulator
It is less dense than water and doesn't conduct heat well
This substance has more H+ than OH-
Acid, pH <7
Community and the physical environment
Ecosystem
This is the result of an organism having adaptations that enable it to survive longer and reproduce more than others of its species
Natural Selection
When performing an experiment, you want to make sure your sample size is large enough so you don't end up with this instead of a causation
Correlation
List the 5 unique properties of water
Solvent
Cohesive/Adhesive
Surface Tension
High Capacity for Heat
Varying Densities
This is a chemical that can resist changes to pH (taking up excess H+ or OH-
