Exploring Life

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.
