Chapter 1 Test Review Flashcards
Biological organization mnemonic device
(M.O.C.T.O.O.P.C.E.B)
My old cat touched only orange people to cut eye balls
Hierarchy of biological organization
Least to most complex
Molecules, organelles, cells, tissues, organs and organ systems, organisms, populations, communities, ecosystems, biosphere
Two major processes of any ecosystem
Cycling of nutrients
One-way flow of energy
Similarities between prokaryotic and eukaryotic cells
Both have DNA and make all living things
Differences between prokaryotic and eukaryotic cells
Eukaryotic cells have a membrane bound nucleus and organelles
Prokaryotic cells do not
Summarize negative feedback
Most common form of feedback in life
Accumulation of an end product of a process slows that process down
Summarize positive feedback
Less common form in life
End product speeds up its production
Three domains of life
Bacteria, archaea, and eukarya
Explain the cycling of nutrients
Circular flow
Recycling
Nutrients go to Plants to animals that die and nutrients are recycled and the process starts over
Explain one way energy flow
Energy flows from sunlight to producers (plants) to consumers (animals)
Hierarchical organization of the traditional Linnaean system
Domain, kingdom, phylum, class, order, family, genus, species
Mnemonic for Linnaean system
(D.K.P.C.O.F.G.S)
Doctor king Philip came over from Germany swiftly
What is the mechanism for descent with modification?
Natural selection–
- Individuals in a population vary in their traits (which are heritable)
- Population can produce more offspring than can survive, therefore there is competition for survival, the best traits are passed on
Who is credited for the Theory of Evolution
Charles Darwin
Domain bacteria
Prokaryotic
Single celled organisms
Domain archaea
Prokaryotic
Single celled organisms
Domain eukarya
Eukaryotic •protists •fungi •plants •animals
Why is evolution considered the core theme of biology?
It accounts for the unity and diversity of life, and for the match of organisms to their environments
What is a controlled experiment?
Experiment that controls an experimental group with a control group where THE TWO GROUPS DIFFER IN ONLY ONE WAY
Explain emergent properties
New properties that arise with each step upward in the hierarchy
Cannot function alone
Arise due to the arrangement and interactions of parts as complexity increases
Discovery science
Making observations and drawing conclusions
Hypothesis based science
Having a hypothesis and setting up a controlled experiment to draw a conclusion
Explain how structure and function are related
Form fits function
