| biology word |
definition |
| analysis | interpretation of data |
| biology | science that seek to understand the living world |
| active site | a specific portion of an enzyme that attatches to a substrate |
| covalent bond | bond formed by the sharing of electrons between atoms |
| polysaccharide | large marcromolecule formed from monosaccharides |
| substrate | reactant of enzyme |
| eukaryote | organism whose cells contain nuclei |
| prokaryote | a single-celled organism lacking a nucleus |
| active transport | energy requiring process that moves material against gradient |
| cellular respiration | releases energy by breaking down glucose and food molecules with oxygen present |
| diffusion | when molecules move are moved through protein channels |
| facilated diffusion | when molecules are moved through protein channels |
| osmosis | movement of water according to the gradient |
| photosynthesis | process inwhich autotrophs use light to convert water, co2, into energy compounds usable by the plant; glucose |
| cell cycle | series of events that the cell goes through to grow and divide |
| crossing over | during meiosis; when genes of one chromosome switch onto another chromosome while forming a tetrad |
| diploid | a cell with two homolohous chromosomes (pairs) |
| haploid | a cell containing one pair of homologous chromosomes |
| point mutation | mutation |
| replication | copying process in which cell duplicates its |
| transcription | copyong DNA into RNA format |
| translation | copying RNA into protein synthesis |
| heterozygous | organism that has two different alleles for one trait |
| homozygous | organism that has one pair of the same alleles |
| hybrid | offspring of crosses between parents of different traits |
| incomplete dominance | situation in which one allele is not completely dominant over the other |
| principle of independent assortment | alleles of different genes; usually segregated |
| principle of dominance | one allele may be expressed all alone |
| autotroph | an organism that makes its own food |
| biodiversity | total of variety of organisms in the biospherean organism that obtains energy throught the consumation of other animals |
| carnivore | an organism that obtains energy through the consumation of other animals |
| commensalism | process in which one member is helped, the other is normal |
| consumer | organisms that gains energy by consuming other organisms |
| decomposer | organisms that gain energy through dead organisms |
| food chain | series of steps in which energy is transformed by being consumed |
| food web | complex interactions formed by feeding relationships between many organisms |
| herbivore | organism that obtains energy by eating only plants |
| heterotroph | organism that eats for energy; called a consumer |
| limiting factor | factor that causes the growth of the population to decrease |
| mutualism | when both organisms benefit from the relationship |
| omnivore | eats bothe plants and animals for energy |
| parasitism | when 1 organism is benefited and the other has loss in relationship |
| succession | a series of predictable changes overtime |
| trophic level | a step in food chain or food web |
