Question | Answer |
Science that deals with the composition of matter | Chemistry |
Elements, atoms, molecules, compounds, mixtures are? | Fundamental forms of matter |
Substance from which all matter is made | Element |
Fundamental Unit that makes up chemical elements | Atom |
no charge | neutron |
positive charge | proton |
negative charge | electron |
If outermost energy level has less than four electrons but greater than 8, the atom will complete level by gaining electrons | nonmental |
If outermost shell hass less than four electrons, the atom normally loses electrons to complete level. | Metal |
combination of two or more atoms | molecule |
Molecules formed by the union of two or more different atoms | Compound |
Compound made of few elements | Simple Compound |
Compound made of many elements | Complex Compound |
Blends of two or more substances | Mixture |
Mixture in which component substances remain evenly distributes | Solution |
Mixture in which material distributed in the solvent settles out unless constantly shaken | suspension |
mixture in which the particules don't dissolve but remain dissolved in the solvent because they are so small | Colloidal suspension |
Dissolving substance | solvent |
The substance that is dissolved | Solute |
+ charge ion | cation |
- charge ion | anion |
opposites attract, + atom comes in contact with a - atom and - gains electrion from + | Ionic bond |
sharing involves sharing of electrons between the atoms in the molecule | Covalent Bond |
Chemical substance capable of donating a hydrogen ion to another substance | Acid |
Chemical substance usually containing a hydrogen ion, that can accept a hydrogen ion | Base |
Chemnicals that maintain balance | Buffers |
All chemical compounds that characterize living things | Organic Compounds |
simple sugars used for energy | Carbohydrates |
fats made from glycerol in combo with fatty acids | lipid |
May contain nitrogen, sulfer, and phosphorus. Structural materials of the body such as muscle, bone, connective tissue, and hair, eye, skin pigment Building block=Amino acids | Protein |
Function as catalysts | Enzymes |
Shape is important, Must match the shape of the substance with which the enzyme combines | Lock and Key Method |
Basic unit of all life. Simples structure that shoes all life characteristics | cell |
two sets of lenses used in most labs | modern compound light |
combo of magnifications and enlargement can magnify up to one million times or more | transmission electron |
three demensional picture, Magnification approx 250,000 | scanning electron |
outer covering of cell made up mainly of a double layer of lipid molecules | plasma membrane |
main substance that fills cells and hold cell contents. suspension of nutrients minerals enxymes and other specialized material in H20 | Cytoplasm |
little organs specialized structures perform different tasks | Organelles |
control center of a cell | nucleus |
inside nucleus, act in manufacture of proteins | nucleolus |
protein formations | ribosomes |
network of membranes | endoplasmic reticulum |
bean shaped, power house | mitochrondia |
rod shaped, cell division | centrioles |
contains digestion enzymes | lysosomes |
forms special substances released from cells | golgi apparatus |
consists of three items, phosphate unit, nitrogen base, sugar unit | nucleotide |
contant movement from high concentration to lower concentration | diffusion |
diffusion of water through semipermeable membrane | osmosis |
passage of water containginb dissolved material through a membrane as a resut of a mechanical force on one side | filtration |
molecules move in the opposite direction than would normally flow | active transport |
engulging large particles by cell membrane | phagocytosis |
engulging droplets of fluid by cell membrane (cell drinking) | Pinocytosis |
solutions have the same concentration of molecules as the fluids with in the cell | isotonic |
solution is less concentrated than intracellular fluid therefore cell placed in this solution will draw water in, swell, and burst | hypotonic |
solution has higher concentration than cell fluids therefore cell loses water and shrinks | hypertonic |
