|
|
__________ is the complex molecule that stores the hereditary information in all living organisms.
|
DNA (deoxyribosenucleic acid)
|
|
|
What are organelles?
|
tiny compartments w. in cells within which cellular activites are organized.
|
|
|
what are cells?
|
Membrane bound units, the smallest living level of organization.
|
|
|
What are tissues?
|
groups of similar cells that act as a functional unit
|
|
|
What are organs?
|
body structures composed of several different tissues grouped together in a structural and functional unit.
|
|
|
what is an organ system?
|
multiple organs grouped together to serve one functionality.
|
|
|
What is a population?
|
a group of species living in the same area
|
|
|
what is a species?
|
its members are similar in appearance and are able to interbreed.
|
|
|
what is a community?
|
populations of different species living in the same place.
|
|
|
what is an ecosystem?
|
a biological community and the soil and water with in which it lives together.
|
|
|
What are emergent properties?
|
novel properties that emerge, properties that were not present at the simpler level of organization.
|
|
|
Evolution
|
genetic change in a species over time.
|
|
|
Natural Selection
|
those organisms whose characteristics make them better able to survive the challenges of ther environment live to reproduce passing their favorable characteristics onto their offspring
|
|
|
Artificial Selection
|
Selection of traits among a population under contrived conditions
|
|
|
Explain the flow of energy in biology.
|
All the energy used by most organisms comes from the sun and is gradually used up as it passes in ONE direction through ecosystems.
|
|
|
Symbioses
|
Organisms of 2 different species that live direct contact
|
|
|
______ determines function.
|
Structure
|

|
|
Explain the cell theory
|
all living organisms consist of cells
|
|
|
Explain the gene theory
|
the proteins and RNA molecules encoded by an organism's genes determine what it will be like.
|
|
|
DNA

the entire set of DNA instructions that specifies a cell.
|
|
|
Explain the theory of heredity.
|
it is the unity of life, the genes of an organism are inherited as discrete units.
|
|
|
Chromosome
|
the vehicle in which heredity information is physically transmitted from one generation to the next.
|
|
|
Explain the theory of evolution.
|
it is the diversity of life, that attributes the diversity of the living world to natural selection.
