Hypothesis (declarative statement)
Prediction (If ....., then......)
the smallest particle of an element that displays the properties of the element
negative subatomic particle, moving about in an energy level around the nucleus of an atom
a positive subatomic particle, located in approximately one atomic mass unit.
neutral subatomic particle, located in the nucleus and having a weight of approximately one atomic mass unit
number of protons within the nucleus of an atom
chemical bond in which atoms share one pair of electrons
chemical bond in which ions are attracted to one another by opposite charges
a charged particle that carries a negative or positive charge
power of hydrogen ions. Smaller the pH number the more acidic the solution
Larger the pH number, the more basic the solution
Neutral is 7 on the pH scale
molecules that raise the hydrogen ion concentration in a solution and lower its pH numerically.
molecules that lower the hydrogen ion concentration in a solution and raise the pH numerically
has a pH of 7
a substance or group of substances that tend to resist pH changes of a solution, thus stabilizing its relative acidity and basicity.
union of 2 or more atoms of the same element; also, the smallest part of a compound that retains the properties of the compound
maintenance of normal internal conditions in a cell or an organism by means of self-regulating mechanisms.
one of two or more atoms with the same atomic number but a different atomic mass due to the number of neutrons
the process by which an unstable nucleus emits one or more particles or energy
type of molecule that interacts with water by dissolving in water and/or forming hydrogen bonds with water molecules
type of molecule that does not interact with water because it is nonpolar
substance in which a solute is dissolved to form a solution.
loss of normal shape by an enzyme so that it no longer functions; caused by a less-than-optimal pH or temperature
type of protein found in all living things that changes the rate of chemical reaction.
a chemical reaction in which two or more simple substances combine to form a new, more complex substance
The process by which a gas changes to a liquid.
the splitting of a compound by the addition of water, with the H+ being incorporated in one fragment and the OH- in the other.
Process in which a receiving neuron releases an enzyme into the synapse, breaking down neurotransmitters into other biochemicals
a type of lipid molecule having a complex of four carbon rings; i.e. cholestorol, prgesterone, and testosterone
a molecule that forms the bi-layer of the cell's membranes; has a polar; hydrophilic head bonded to two nonplolar, hydrophobic tails
Family of elements (18) with a full outer enrgy level (full set of valence electrons). They do not bond with other atoms. Include Helium, Neon, Argon, and Krypton to name a few.
cellular structure, exisiting in pairs, that possibly organzies the mitotic spindle for chromosomal mmovement during mitosis and meiosis
threads in the nucleus composed of DNA and proteins
chromatin condensed into a compact structure
contents of a cel betweenthe nucleus and the plasma membrane that contains the organelles
internal framework of the cell, consisting of micrtubules, actin filaments, and intermedidate filaments
organelle, consisting of saccules and vesicles, that processes, packages, and distributes molecules about or from the cell.
flexible double layered sheet that makes up the cell membrane and forms a barrier between the cell and its surroundings
membrane-bound vesicle that contains hydrolytic enzymes for digesting macromolecules
cylindrical structure that contains 13 rows of the protein tubulin around an empty central core; present in the cytoplasm, centrioles, cilia, and flagella
powerhouse of the cell, produces energy (ATP) from oxygen and sugar(Cellular respiration)
surrounds the nucleus and controls what enters and leaves the nucleus
dark-staining, spherical body in the cell nucleus that produces ribosomal subunits out of the nucleus
