Bio Midterm 1 Flashcards
The study of life: biology or ecology
Biology
The perspective or collection of presuppositions a person uses to view and interpret the world: world view or interests
Worldview
The physical stuff that makes up the universe. Anything that occupies space and has mass: organ or matter
Matter
A pure substance made of only one kind of atom: esophagus or element
Element
A measurement of the average speed of the particles within a substance: septum or temperature
Temperature
a chemical reaction that releases energy by light or heat: exothermic reaction or growth hormone
Exothermic reaction
a process or reaction in which the system absorbs energy from its surroundings: endothermic reaction or enzymes system
Endothermic reaction
I naturally occurring catalyst, usually a protein: family or enzyme
Enzyme
To opposite ends: polarity or retina
Polarity
The attraction of particles in one substance for particles in a different substance: antenna or adhesion
Adhesion
The attraction between like particles within polar substances: cohesion or domain
Cohesion
The sum of all the habitable ecosystems on the earth: biosphere or ecosphere
Biosphere
The study of the interrelationships between living things and their physical environments: gestation or ecology
Ecology
The set of plants and animals that are adapted for life in those parts of earth characterized by a particular climate: biome or centromere
Biome
The role of an organism within its habitat: niche or organ
Niche
A group of organisms of the same species living and interacting with in the same geographic area: population or ribosome
Population
Living or derived from living things: biotic factors or cell body
Biotic factors
non-living chemical and physical parts of the environment: cell theory or abiotic factors
Abiotic factors
The average weather in an area over an extended length of time: climate or divergence
Climate
an organism that produces complex organic compounds from simple substances present in its surroundings: autotrophs or cerebellum
Autotrophs
an organism deriving its nutritional requirements from complex organic substances: heterotrophs or insulin
Heterotrophs
The conflict that results when organisms attempt to use the same resources: mma or competition
Competition
a linear network of links in a food web starting from producer organisms and ending at predator species: food chain or food line
Food chain
The process of getting energy by burning wood, and other organic matter: biosphere or biomass
Biomass
3 types of symbiosis
Commensalism, mutualism, parasitism
a pathway by which a chemical substance moves through biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth.
Biochemical cycles
The conversion of nitrogen gas into nitrogen compounds that living things can use: fermentation or nitrogen fixation
Nitrogen fixation
The number of organisms in a defined unit of area: retrovirus or population
Population
A measurement of the variety of life in a particular ecosystem: catalyst or biodiversity
Biodiversity
A rate of population growth in which the population size multiplies at a constant rate at regular intervals: exponential growth or excavation rate
Exponential growth
The human demand on nature: ecological footprint or pollution
Ecological footprint
A gas that can trap heat in the earths atmosphere such as carbon dioxide or water vapor: GlucaGen or greenhouse gas
Greenhouse gas
A technique that uses organisms to remove or neutralize hazardous waste in the environment, such as oil spills
Bioremediation
One of the fundamental models of biology that states that cells are the smallest form of life come from P existing cells are the basic building blocks of all life forms and carry out life processes to maintain homeostasis
Cell theory
An organism consisting of only one cell
Unicellular
An organism consisting of two or more cells
Multicellular
Describes cells having a true nucleus as well as membrane bound organelles
Eukaryotic
Describe cells that don’t have a true nucleus
Prokaryotic
A group of cells that are specialized to perform a particular function: trachea or tissue
Tissue
A group of cells that live and work together: colony or domain
Colony
The structure within cells that helps to find their shape: cytoskeleton or chlorophyll
Cytoskeleton
A whip like cellular organelle and used for movement in many bacteria: flagellum or gizzard
Flagellum
The cellular organelle found in plants that contains the pigment chlorophyll and is where photosynthesis takes place: coagulation or chloroplast
Chloroplast
