7. Regulation-
Regulatory Mechanisms
ensure balance in Life
Regulatory Mechanisms
Negative feedback- accumulation of
product inhibits an enzyme in the
production sequence of product
QuickTime™ and a
decompressor
are needed to see this picture.
Regulatory
Mechanisms
Positive feedback- accumulation of
product enhances an enzyme
increasing production of product.
Platletes aggregate @ cut, chemicals

EVOLUTION, UNITY, DIVERSITY
EVOLUTION IS THE CORE
THEME
•Species change over time
EVOLUTION IS THE CORE
THEME
•Species change over time
•Populations have potential
to produce more offspring
than can be supported.
EVOLUTION IS THE CORE
THEME
•Species change over time
•Populations have potential
to produce more offspring
than can be supported.
•Natural selection
EVOLUTION IS THE CORE
THEME
Similar species share a
common ancestor on
phylogenic tree
•All life connected and traced
back to prokaryotes
EVOLUTION, UNITY, DIVERSITY
Diversity of all life TaxonomyUnity of all lifecell structure, DNA,
metabolic pathways
Scientific Processes
1. Asking a question
John Endler Univ of Cal - why is there a significant difference in
populations of guppies regarding average age and size @ sexual
maturity?
Scientific Processes
2. Hypothesis testable, tentative
explanation for what we
observe.
Could it be the predator
which preys predominately
on the population?
Scientific Processes
3. Prediction - if/then (If the
hypothesis is true, then the
results of the experiment will
be…)
IF, guppies from Pike-Cichlid
pools are introduced to new
pools th,at contain only
killifish THEN, the average
age and size at maturity will be
heavierand older than
nontransplanted individuals
Scientific Processes
4. Testing the validity of the
hypothesis
Control Group - the group not moved
Experimental Group - the group that was
moved to the pool with only killifish, and
no guppies
Scientific Processes
5. Conclusion
