assimilation- changing of absorbed substances into chemically different forms
circulation
reproduction
growth
what are the requirements of life? - Answer water
,food
heat
pressure
oxygen
define homeostasis - Answer maintaining of a stable enviroment
what is a homeostatic mechanism - Answer monitors aspects of internal environment and corrects as
needed
*negative feedback mechanism
define matter - Answer anything that takes up space and has mass
element - Answer composed of chemically identical atoms
atom - Answer smallest particle of atom, basic unit of matter
what are structure of an atom - Answer nucleus
protons
neutron
electrons
define nucleus, proton, electron, neutron - Answer nucleus- central part of atom
proton- positive charge
electron- negative charge
neutron- no electrical charge
ionic bond - Answer formed when electrons are transferred from one atom to another
, what are covalent bonds - Answer when two molecules share electron
hydrogen bond - Answer formed between water molecule, attraction between positive end of polar
molecule and negative end of another polar molecule
define synthesis, decomposition, and exchange reactions - Answer Synthesis- A+B=AB
Decomposition- AB=A+B
exchange- AB+CD=AD+BC
define reactant - Answer starting materials of reactions
product - Answer ending material
define catalyst - Answer a substance that speeds up a chemical reaction
what is an acid - Answer dissociates with water
base - Answer combines in water
what happens to salts when dissolved in water and what is produced? - Answer The salt molecules are
"torn apart" by the water, and are reduced to sodium (Na+) and chlorine (Cl-) ions.
what is the pH scale? what ions are involved in the pH scale? - Answer pH scale- indicated the
concentration of hydrogen ions in a solution, H+ and OH-
organic molecule - Answer contains Carbon and hydrogen and dissolves in water.
inorganic molecule - Answer does not contain C and H and dissociates with water
