SCIENCE FINAL STUDY GUIDE
THE STUDY OF LIFE
- Scientific method
- Energy
- Homeostasis
- Qualitative
- Quantitative
Scientific method-
Procedures that biologists and other scientists use to gather information and answer questions.
Energy -
The ability to cause change, organisms use energy to preform biological functions.
Homeostasis-
Organisms regulation of its internal environment to maintain conditions suitable for survival.
Qualitative -
Relating to, measuring, or measured by the quality of something rather than it's quantity.
Quantitive -
Relating to, measuring, or measured by the quantity of something rather than its quality.
PRINCIPLES OF ECOLOGY
- Heterotroph
- Autotroph
- Symbiosis
- Relationships
- Abiotic
- Biotic
- Ecology
- Consumer -decomposed, herbivore, omnivore.
Heterotroph -
Organisms that can not make their own food, and must feed on other organisms for food and nutrients.
Autotroph -
Organisms that use energy from the sun or energy stored in chemical compounds to manufacture their own nutrients.
Symbiosis -
Permanent, close association between two or more organisms of a different species.
Relationships -
The way in which two or more concepts, objects, or people are connected, or the state of being connected.
Abiotic -
Non living parts of an organisms environment.
Ecology -
Scientific study of interactions between organisms and their environments.
Biotic -
All the living organisms that inhabit an environment.
Ecology -
The scientific study of interactions between organisms and their environments.
COMMUNITIES AND BIOMES
- Tolerance
- Successions
- Pioneer species
- Climax community
- Biome
Tolerance -
As the body becomes less responsive to a drug and an individual needs larger or more frequent doses of the drug to achieve the same effect.
Successions -
A number of people or things sharing a specified characteristic and following one after the other.
Pioneer species -
The first to colonize previously disrupted or damaged ecosystems.
Climax community -
The final stage of succession, remaining relatively unchanged until destroyed by an event such as fire or human interference.
Biome -
A large naturally occurring community of flora and fauna occupying a major habitat like a forest or tundra.
POPULATION BIOLOGY
- Density - dependent and independent
- Population graphs
- Limiting factor
- Carrying capacity
- Immigration
- Emigration
Density -
The degree of compactness of a substance.
Population graph -
A graph showing the growth and declination of an ecosystem/ habitat.
Limiting factor -
The factor(s) that limit the reaction rate in any physiological process governed by many variables/ the environmental factor that is of predominant importance in restricting the size of a population.
Carrying capacity -
The number or quantity of people or things that can be conveyed or held by a vehicle of container, but in this case a habitat/ environment.
BIOLOGICAL DIVERSITY AND CONSERVATION
- Endangered
- Extinct
- Threatned
- Biodiversity
- Fragmentation
- Reintroduction
- Conservation biology
Endangered -
Seriously at risk of extinction
Extinct -
Having no living members.
Threatened -
Cause to be vulnerable at risk and danger.
Biodiversity -
The variety of life in the world or in a particular habitat or ecosystem.
Fragmentation -
The process or state of breaking or being broken down into small or separate pieces.
Reintroduction -
The action of bringing something into existence or effect again. Bringing a new species into a new habitat
Conservation biology -
This branch of biology deals with threats to biodiversity to plants and animals.
THE CHEMISTRY OF LIFE
- Atom structure
- Electrons in shells
- Ions
- Macromolecules
- Polymer
- Monomer
- Disaccharide
- Monosaccharide
- Acid
- Base
Atom structure -
Positively charges nucleus and negatively charged electrons circling around it. All within an atom
Electrons in shells -
The outside part of an atom around the atomic nucleus.
Ions -
An atom or molecule with the net electric charge due to the loss or gain of one or more electrons.
Macromolecules -
Subunits of molecules containing protein, nuclei acid, and synthetic polymer.
Polymer -
Consists of a large number of similar units bonded together.
Monomer -
A molecule that can be bonded to other identical molecules to form a polymer.
Disaccharide -
Any class of sugars whose contain two monosaccharides residues.
Monosaccharide -
Any of the class sugars.
Acid -
A chemical substance that is sour tasting and dissolves substances.
Base -
Water soluble compound that reacts with acid.
Organelles -
Any of a number of organized or specialized structures which in a living cell.
Cell theory -
The cell is a fundamental structure of living matter. All cells come from other cells, and an organism is composed of one or more cells.
