A | B |
carrying capacity | number of organisms of one species that an environment can support indefinitely |
Exponential growth | J shaped growth, population growing at a very fast rate |
logistic growth | S shaped growth, population is cycling at or slightly above or below carrying capacity |
density dependent factors | factors that affect population growth that depend on a large population, ex. disease |
density independent factors | factors that affect population regardless of population numbers, ex. hurricane |
exotic or alien (nonnative) species | species that are not native to the area but are introduced to that area |
invasive species | growth of the species takes over an area, ex. Kudzu |
pH | the amount of Hydrogen in solutions |
acid | solution that forms H+ in water, ex. lemon |
base | solution that forms OH- in water, ex. baking soda |
solution | mixture of solutes distributed equally in a solvent |
solvent | part of solution doing the dissolving, ex. water |
solute | part of solution being dissolved, ex. sugar |
amino acids | monomers (small parts) of proteins |
carbohydrate | a biomolecule composed of carbon, hydrogen, and oxygen with a ratio of 1:2:1, ex. C6H12O6 |
monosaccharides | simple sugars or pure sugars, contain only one type, ex. glucose |
disaccharides | two monosaccharides combine to make a carb, ex. sucrose |
polysaccharides | polymers of many monosaccharides, ex. starch |
lipids | large biomolecules that are mostly carbon and hydrogen, small amounts of oxygen, ex. fats and oils |
proteins | large, complex polymer composed of carbon, hydrogen, oxygen, and nitrogen, ex. hemoglobin |
peptide bonds | bond that holds amino acids together |
enzyme | proteins that speed the rates of reactions inorganisms |
nucleic acids | complex biomolecule that store cellular information in genetic code, ex. DNA and RNA |
nucleotides | small subunits that make up nucleic acids |
RNA | nucleic acid used in making proteins |
DNA | nucleic acid used to determine how an organism looks |
metabolism | all the chemical reactions that occur within an organism |
ose | three letter ending of most sugars, ex. fructose |
ase | three letter ending of most enzymes, ex. sucrase |
covalent bonds | atoms sharing electrons, most compounds in organisms |
