definition of homeostasis - ANSWER: the maintenance of a constant internal
environment
define a negative feedback loop - ANSWER: changes are met with responses that
restore the balance back to the original state
define a positive feedback loop - ANSWER: changes are met with responses that
amplify themselves until balance is restored
describe a covalent bond - ANSWER: *typically between nonmetals

describe a hydrogen bond - ANSWER: weak bond between a hydrogen atom and a
pair of other atoms that have a high affinity for electrons
describe a synthesis reaction - ANSWER: *occurs when two or more simple
compounds combine to form a more complicated one
*requires energy (endothermic)
describe a decomposition reaction - ANSWER: *occurs when a complex molecule
breaks down to make simpler ones
*releases energy (exothermic)
define a reactant - ANSWER: start the reaction
define a product - ANSWER: what you're left with after a reaction
