5001038129	Isotopes	Atoms of the same element with different numbers of neutrons	2
5001040563	radioactive decay	the spontaneous release of material from the nucleus of radioactive isotopes	3
5001042319	half-life	the time it takes for one-half of an original radioactive parent atom to decay	4
5001045550	covalent bond	the bond formed when elements share electrons	5
5001047064	ionic bond	a chemical bond between two ions of opposite charges	6
5001048446	Hydrogen bond	weak chemical bond the forms when hydrogen atoms that are covalently bonded to one atom are attracted to another atom in another molecule	7
5001052233	polar molecule	a molecule in which one side is more positive and the other side is more negative	8
5001054353	surface tenstion	a property of water that results from eh cohesion of water molecules at the surface of a body of water and that creates a sort of skin on the water surface	9
5001058258	Capillary action	a property of water that occurs when adhesion of water molecules to a survade is stronger than cohesion between the molecules	10
5001060174	acid	contributes hydrogen ions to solution	11
5001062119	base	a substance that contributes hrdoxide ions to soulction	12
5001063460	pH	The number that indicates the relative strength of acids and bases in a substance	13
5001078266	Inorganic compound	compound that does not contain the element carbon or contains carbon bound to element other than hydrogen	14
5001081354	organic compound	compound that contains carbon-carbon and carbon-hydrogen bonds	15
5001138682	Nucleic acid	Organic compounds found in all living cells	16
5001142176	DNA	A nucleic acid, the genetic material that contains the code for reproducing the components of then next generation, an which organism pass on their offspring	17
5001147120	RNA	A nucleic acid that translates the code stored in DNA, which makes possible the synthesis of proteins	18
5001154278	Lipid	a smaller organic biological molecule that does not mix with water	19
5002762669	First law of thermodynamics	energy can't b created or destroyed but can change from one form to another	20
5002766094	Second law of thermodynamics	when energy is transformed the quantity of energy remains the same, but its ability to do work diminishes and entropy of the universe is increased	21
5002772813	energy efficiency	ratio of amt of energy expanded in one form you wan total amount of energy that is introduced into the system	22
5002786076	Open system	exchanges of energy or matter occur across system boundaries	23
5002788888	Closed system	in which energy exchanges do not occur across boundaries	24
5002800914	negative feedback loop	system responds s to a change by return to its orniganl state or by decreasing rate at which change occurs	25
5002805045	positive feedback loop	change in system is amplified	26
5002907069	Energy Quality	the ease with which an energy source can be used for work	27
5002925553	Why is water such an important component of most environmental systems?	Water supports life on earth because humans and animals alike rely on it for survival. Also its unique properties such as capillary action and surface tension support various species in ecosystems such as water striders.	28
5002929059	how are the first and second laws of thermodynamics influenced by environmental science?	State laws and then explain how they are connected: This affects environmental systems because the varying forms of energy in ecosystems determines what species can survive in said systems such as thermal energy heating up effects what animals can survive in water	29
