Chapter One: Exploring Life

Chapter One Exploring Life
1.1) Biologists explore life from the
microscopic to the global scale 1.2)
Biological systems are much more than the sum of
their parts 1.3) Biologists explore life
across its great diversity of species

Welcome to the Team!

• Meet the coaches
• Summarizing Coach J. Fox
• Clarifying Coach E. McLaughlin
• Predicting Coach B. Calabrese
• Questioning Coach C. Fornaca

Get the Basics!

• Hierarchy of Biological Organization
• 12 levels starting from Biosphere to Atom.
• Cells are the smallest level that can perform all
  activities for life. 9th level
• Reductionism
• Species are classified in Taxonomy
• Three Domains Bacteria, Archaea, and Eukarya
• Natural Selection survival of the fittest
• Hypothesis so they can make a prediction
• Test Hypothesis to see if the prediction is
  correct
• Theory is made up of hypothesises.
• Science is a very social subject

Do you Get it?

• Energy Conversion Wheres the batteries?
• Everything works together, living organisms live
  and feed off each others energy.
• Only Two Cell Types Eukaryotic Prokaryotic
• Negative Positive Feedback Simple Terms ?
• Both Forms of regulation
• Negative Slows/ Ends a process
• Positive Speeds/ Continues a process
• Enzymes vs. Catalysts Say whaa?
• A Catalyst is a chemical agent that changes the
  rate of a reaction.
• An Enzyme is a protein acting as a catalyst.
• An enzyme can act as a catalyst but a catalyst
  can not be an enzyme like squares and rectangles

You Should Care!

• We will study Eukaryotic and Prokaryotic Cells in
  chapter 6, which involves the study of cells and
  their functions in living organisms.
• We will study feedback in chapter 40, when we
  study how the body regulates its own temperature
  using evaporative heat loss.

Know Your Stuff?

• How would a tree make use of all the non-living
  factors in its environment?
• How does that tree interact with other living
  organisms in its environment?
• How does the flow of sunlight affect consumer
  organisms?
• Give an example of the process of cycling
  nutrients.
• What is the basis for all reproduction and the
  growth and repair of multicellual organisms?
