Regulatory Mechanisms ensure balance in Life
53
Regulatory Mechanisms Negative feedback-
accumulation of product inhibits an enzyme in the
production sequence of product
54
Regulatory Mechanisms
Positive feedback- accumulation of product
enhances an enzyme increasing production of
product.
55
Regulatory Mechanisms
Platletes aggregate _at_ cut, chemicals released by
platletes attract MORE platletes

EVOLUTION, UNITY, DIVERSITY
57

• EVOLUTION IS THE CORE THEME
• Species change over time

58

• EVOLUTION IS THE CORE THEME
• Species change over time
• Populations have potential to produce more
  offspring than can be supported.

59

• EVOLUTION IS THE CORE THEME
• Species change over time
• Populations have potential to produce more
  offspring than can be supported.
• Natural selection

60

• EVOLUTION IS THE CORE THEME
• Similar species share a common ancestor on
  phylogenic tree
• All life connected and traced back to prokaryotes

61

• EVOLUTION, UNITY, DIVERSITY
• Diversity of all life -
• Taxonomy-
• Unity of all life-
• cell structure, DNA,
• metabolic pathways

62
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 _at_ sexual
maturity?
63

• Scientific Processes
• 2. Hypothesis -
• testable, tentative explanation for what
  we observe.

Could it be the predator which preys
predominately on the population?
64

• 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
65
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
66
Scientific Processes 5. Conclusion
