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.

Consumer -
Take in

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.

Immigration -
Coming to

Emigration -
Leaving from

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.

A VIEW OF THE CELL

  • Organelles
  • Cell theory

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.
