fall 2009 SRJC BIO 10 with C. Brown
| Question | Answer |
|---|---|
| Biosphere | The total life zone of the earth's surface, including those parts of the atmosphere, water, soil, and rocks in which living things occur. |
| Biome | A complex biotic region covering large portions of the earth and characterized by distinctive life forms of enduring (climax) communities; examples include desert, tropical rain forests, tundra. |
| Ecosystem | A group of populations in a given area which interact with each other and the physical part of the environment in which they live. |
| Community | A group of interacting populations of different species that inhabit a given area. |
| Population | A group of interacting individuals of the same species that inhabit a given area; examples include a herd of reindeer, baboon troop, group of pond lilies. |
| Organism | An individual living entity which carries out all life functions; examples include a human, an elephant, an oak tree, a fern. |
| Organ-System | A group of organs that perform a specific function; digestive system, circulatory system, reproductive system. |
| Organ | A body part usually composed of several tissues grouped together into a structurla and functional unit; examples include heart, liver, stomach. |
| Tissue | An aggregate of cells, usually similar in both structure and function, that are bound together by intercellular material; muscle tissue, fat tissue, skin. |
| Cell | A microscopic structural and functional unit of most living things, consisting of a cytoplasm surrounded by a limiting membrane. |
| Organelles | A well defined part of a cell, often bounded by a membrane, and having a specific function |
| Macro molecule | A very large organic molecule (polymer) consisting of many repeating smaller organic molecules (monomers). Examples: protein, cellulose, DNA |
| Molecule | A chemical unit consisting of two or more atoms joined together by chemical bonds; EX: water, sugar, carbon dioxide. |
| Atom | The smallest unit of an element, not divisible by ordinary chemical means; EX: hydrogen, carbon, oxygen, nitrogen. |
| Subatomic Particles | Small units making up an atom, such as electrons, protons and neutrons, |
| Anabolism | All metabolic processes which synthesize large complex molecules from smaller ones; the building up of a new protoplasm. |
| Catabolism | A metabolic process that breaks large molecules into smaller molecules. Often accompanied by the release of heat. |
| Homeostasis | adaptations of an organism or cell to environmental stresses; maintenance of constancy of basic functions by varying accessory functions; dynamic equilibrium or steady internal state. |
| Nitrate Bacteria | Bacteria which convert nitrites into nitrates. |
| Denitrifying Bacteria | Bacterial which break down nitrates and other nitrogenous compounds releasing free nitrogen into the environment. |
| 1st law of Thermodynamics | Energy is neither created nor destroyed when converted from one form to another. |
| 2nd law of Thermodynamics | When energy is converted from one form to another, some is lost in the form of heat and therefore cannot perform work. |
| Entropy | The measure of the eof disorder in a system. |
| Heat | Energy in the form of infrared radiation. |
| Dynamic | A continuously changing identifiable function, condition or entity such as the life process of cells, organisms or ecosystems. |
| Daily Periodicity | Daily re-occurrence of some biological phenomenon (also called circadian rhythm). |
| Lunar Fluctuations | Increase and decrease of some biological, phenomenon which coincides with the moons cycle around earth. |
| Seasonal Cycles | Changes in biological activity due to the change of seasons. |
| Succession | A gradual and predictable series of species composition in an ecosystem from the time of first colonization to the mature stable climax community. |
| Sere | One of the stages of succession |
| Climax Community | A stable community at the final stage of succession which is in equilibrium with the current physical environment. |
| Continental Drift | The gradual drifting or movement of continents that occurs over billions of years. |
| Population | A group of interacting individuals of the same species which inhabit a given area. |
| Abundance | The total number of individuals in a population. |
| Geographic Distribution | The total area and geographical location of a population. |
| Dispersion | The internal distribution pattern of the individuals of a population in the area they inhabit. |
| Density | The number of individuals of a population per unit area. |
| Age Distribution | The proportion of individuals of a population in each age group. |
| Variation | Differences which exist among individuals of the same age and sex. |
| Random Dispersion | The internal distribution pattern of a population in which each individual has an equal and independent of occurring at any given point. |
| Clumped dispersion | the internal distribution pattern of a population in which the individuals occur in close aggregations |
| Parthenogenesis | The development of an organism from an egg which has not been fertilized. |
| Clone | Genetically identical cells or organisms produced from a common ancestor by asexual means. |
| Morphological Variation | Differences among individuals of the same age and sex which are due to shape, structure or color. |
| Behavioral Variation | Differences among individuals of the same age and sex due to biochemical and cellular processes. |
| Normal Curve Distribution | A graphical representation of variation in a population which has specific mathmatical dimensions. |
| Immigration | The rate at which new individuals are added to a population from other areas |
| Emigration | The rate at which new individuals are lost from a population by dispersal to other animals. |
| Population Fluctuations | The periodic increase and decrease in numbers of individuals of a population. |
| Food availability | The amount of nutrients which are accessible to a population. |
| Absolute Food Shortage | Low availability of all nutrients (food is not present in any quantity); not enough calories to do a day's work; undernutrition |
| Relative Food Shortage | A shortage of nutrients due to low accessability (food present but in low concentrations); unbalance diet; malnutrition |
