| 599242373 | Biology | The scientific study of life | |
| 599242374 | Five Properties of life | Order, Evolutionary Adaptation, Response to Environment, Regulation, Energy Processing, Growth and Developement, and Reproduction. | |
| 599242375 | Levels of Biological Organization | Biosphere, Ecosystem, Communities, Population, Organisms, Organs/Organ System, Tissue, Cells, Oganelles and Molecules | |
| 599242376 | Producers | Plants and other photosynthetic organisms that convert light energy to chemical energy. | |
| 599242377 | Consumers | Organisms that feed on producers and other consumers. | |
| 599242378 | Deoxyribonucleic Acid | (DNA) The substance that make up the chromosomes within the nucleus of our cells that code for our genes. | |
| 599242379 | Genome | Entire "library" of genetic instructions that an organism inherits | |
| 599242380 | Eukaryotic Cells | A cell subdivided by internal membranes into various membrane enclosed organelles including the chloroplast | |
| 599242381 | Prokaryotic Cells | Cells where the DNA is not seperated from the rest of the cell by enclosure in a membrane-enclosed organelles. These also lack the other kinds of membran-enclosed organelles that characterise eukaryotic cells. | |
| 599242382 | System | "The whole is greater than the sum of its parts"....... Combination of components can form a more complex organization. | |
| 599242383 | Emergent Properties | New properties that emerge with each step upward in the hierchary of life | |
| 599242384 | Reductionism | Reducing complex systems to simplier components that are more manageable to study. | |
| 599242385 | Negative Feedback | A change in a physiological variable that is being monitered triggers a response that counteracts the initial fluctuation. Ex: When the body creates too much ATP, the body send feedback that will inhibit an enzyme near the beginning of the pathway. | |
| 599242386 | Positive Feedback | When the end product of a process speeds up the production of that pruduct. Ex: When a blood vessle is broken blood platelets rush to the site which leads to more platelets rushing to the site to clot the site. | |
| 599242387 | Domain Bacteria | Contains all the bacteria and are the most diverse and widespread prokaryotes | |
| 599242388 | Domain Archaea | Contains the prokaryotes that are known to live in the earths extreme environment such as salt lakes and boiling hot springs. | |
| 599242389 | Domain Eukarya | Contains the kingdoms of Protists, Plantae, Fungi, and Animalia. They are all unicellular. |
