Protein Synthesis
 microRNAs
function in transcriptional and
post-transcriptional regulation of gene
expression
Immune system
 Antibody
medited response is sometimes
called Humoral response
Plant Immune system
Plant defenses against pathogens include
molecular recognition systems with
systemic responses; infection triggers
chemical responses that destroy infected
and adjacent cells, thus localizing the effects
Compartmentalization
 Plant
response to a wound or pathogen
 Walls around area thicken
 Toxins and resins are produced at site
Compartmentalization
strong
moderate
weak

Ecology
Mathematical or computer models are used
to illustrate and investigate population
interactions within and environmental
impacts on a community
Ecology
Interactions between populations affect the
distributions and abundance of
populations.
Behavioral Ecology
Animals use visual, audible, tactile, electrical
and chemical signals to indicate
dominance, find food, establish territory and
ensure reproductive success.
Behavioral Ecology
Cooperative behavior tends to increase the
fitness of the individual and the
survival of the population.
