100
This is a substance that can't be broken down into simpler chemical substances
What is an element?
100
This is formed when atoms share electrons.
What is a covalent bond?
100
An example of this is chocolate chips and peanuts.
What is a mixture?
100
This has an unequal distribution of charge; that is each molecule has a positive end and a negative end.
What is a polar molecule?
100
This biomolecule gives quick fuel for the body.
What are carbohydrates?
200
These are needed by living organisms, but only in small amounts.
What are trace elements?
200
This is found in the compound NaCl and is when atoms gain/lose electrons.
What is an ionic bond?
200
This is formed by hydroxide ions.
What is a base?
200
This is the net movement of particles from an area of higher concentration to an area of lower concentration.
What is diffusion?
200
These are fats and oils, waxes, phospholipids, and steroids.
What are lipids?
300
This is allowed up to 18.
What is the third energy level?
300
Water is an example of this.
What is a compound?
300
This has a pH of 7.
What is neutral.
300
When materials or liquids pass in and out of a cell or substance at EQUAL rates, there is no net change in concentration inside the cell or substance.
What is dynamic equilibrium?
300
These are made of 20 different amino acids!
What are protiens?
400
This is an element that has different numbers of neutrons in its nucleus.
What is an isotope?
400
This refers to all of the chemical reactions that occur within an organism.
What is metabolism?
400
When sugar molecules in a powered drink mix dissolve easily in water they form this.
What is a solution?
400
*polar *resists temperature change *expands when it freezes
What are the 3 properties of water?
400
These are special proteins that speed up chemical reactions in the body without raising the body's temperature
What are enzymes?
500
This is inside the nucleus of an atom and tells what element it is.
What is a proton?
500
This is the yield of two reactants.
What is the product?
500
This is a measure of how acidic or basic a solution is.
What is pH?
500
concentration, temperature, and pressure
What 3 factors affect the rate of diffusion?
500
These are found in the cell's nucleus and contain genetic information (DNA/RNA), they are made of nucleotides
