|---|
| Species | Group of organisms that have the same structure and can reproduce together |
| Biodiversity | all the different types of organisms on Earth |
| Ecosystem | interaction of living and nonliving thing |
| population | members of a species living in a specific area |
| Community | Different species in a common area |
| symbiosis | the interactions between different organisms |
| commensalism | happy - nothing |
| mutualism | happy - happy |
| parasitism | happy - sad |
| Resourse Partitioning | Dividing up of resources amongst different species |
| variabilty | variation within a species |
| natural selection | survival of the fittest |
| heritable | characteristic that are passed on to next generation |
| nonheritable | characteristic that are acquired not passed on |
| discrete variation | only having two forms |
| Continuous Variation | having many forms of the same gene |
| binary fission | splitting by dividing in half |
| Budding | Splits off a smaller version of itself |
| spores | identical copies of the plant made from asexual reproduction |
| vegetative reproduction | cuttings, shoots and runners |
| zygote | formed when two gametes join |
| embryo | after zygote grows larger |
| pollen | tree sperm |
| DNA | Deoxyribonucleic Acid |
| 4 Nucleic Acids | G joins with C and A joins with T |
| chromosomes | packages of DNA |
| Gene | a segment of DNA |
| Allele | All the possible forms of the gene |
| trait | same as a gene |
| hybrid | One dominant and one recessive gene |
| Dominant Trait | The allele that is expressed |
| Recessive trait | Appears only if two recessive trait are joined |
| incomplete dominance | a sharing of a trait - red and white make pink |
| overspecialization | an organism that uses a very narrow set of environmental conditions |
| artificial selection | man picks trait to be selected for not nature |
| biotechnology | using organisms to produce agricultural, industrial or medical products |
| In vitro | Manually fertilizing an animal |
| genetic Engineering | Altering DNA by theuse of technology |
| In-situ Conservation | Maintaining populations of wild organisms in their functioning ecosystems |
| Ex-situ Conservation | Conserving components of biological diversity outside of a natural habitat |
