Regulatory Mechanisms ensure balance in Life

Regulatory Mechanisms Negative feedback- accumulation of product inhibits an enzyme in the production sequence of product

Regulatory Mechanisms Positive feedback- accumulation of product enhances an enzyme increasing production of product.

Regulatory Mechanisms Platletes cut, chemicals released by platletes attract MORE platletes

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 phylogenic tree Similar species share a common ancestor on phylogenic tree All life connected and traced back to prokaryotes

EVOLUTION, UNITY, DIVERSITY Diversity Diversity of all life - Taxonomy- Unity Unity of all life- cell 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 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
