Define Molecules
complex clusters of the components that make up atoms.
__________ 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
Homeostasis.
state in which physical and chemical aspects of internal environment are being maintained with in ranges suitable for cell activities.
Deductive thinking
using the general principles to explain specific observations.
Inductive thinking
discovering general principles by careful examination of specific areas.
what are the 5 stages of the scientific method
1. observation
2. hypothesis
3. Predict
4. testing
5. conclude
What are the four theories that unify biology as a science?
1. Cell Theory
2. The Gene Theory
3. The theory of hereditary
4. the theory of evolution
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
(deoxyribosenucleic acid) the basic storage vehicle or central plan of hereditary information.
DNA is stored in a sequence of ________ in a linear _______ ______.
Nucleotides

Nucleotide polymer.
RNA
a particular protien, or different kind of molecule encoded by a gene.
Gene
the baic unit of heredity.
Genome
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.
What are the 3 domains of the living world's diversity?
1. Bacteria, Archaea, Eukarya
