What are the three subatomic particles and what is their electric charge?
Proton - positive charge
Electron - negative charge
Neutron - Neutrally charge
Homeostasis
Maintaining internal conditions
Hydrophobic vs Hydrophilic
Hydrophobic- not attracted to water
Hydrophilic- attracted to water
The law of biogenesis
All life comes from life
What are the three types of energy?
Kinetic energy, potential energy, radiant energy
What are the three great transcendentals?
Goodness, beauty, and truth
A paradigm is a way of seeing and doing something, true or false
True
Covalent bonds
A molecular bond where electrons are shared
Ionic bonds
A molecular Bond where atoms give and take electrons
What is the order of organizing life?

-Kingdom. (King)
-Phyla. (Philip)
-Classes. (Come)
-Orders. (Over)
-Familes. (For)
-Genus. (Good)

What are five scientific characteristics of life?
- Life reproduces
- Life reacts to stimuli
- Life maintains homeostasis
- Life needs food and water
- Life makes adaptions
What are the properties of water?
- water is very dense (denser than ice)
- water possesses amazing surface tension
- water is known as the universal solvent because it is very good at dissolving things
- water has a very high heat capacity (that means it’s very hard to change its temperature)
- Water often in liquid form
- water is very sticky
Give two examples of how the adhesive and cohesive properties of water allow for Life as we know it
-They allow for precipitation
-They allow for due on plant roots which help plants grow
What are the four groups of biomolecules?

Which three elements are found in every lipid?
Carbon, hydrogen, oxygen (cho)
Which elements are found in proteins?
Carbon, hydrogen, oxygen, nitrogen, sulfur, selenium (cho nss)
What elements are found in nucleic acids?
Carbon, hydrogen, oxygen, nitrogen, phosphorus (cho np)
What are the monomers of the polymer macromolecules?
Proteins- made of amino acids
Lipids - fatty acids and glycerol
Nucleic Acids- DNA and RNA made of nucleotides
Carbohydrate- monosaccharides (like glucose, fructose, and other sugars)
What is Lactose?
Dimer: found in milk
What is Starch?
Polymer; energy storage in plants
What is Sucrose?
Dimer: table sugar
What is Glucose?
Monomer: common fuel source for life
What is Fructose?
Monomer: very sweet, found in fruit
