Folks:
Homework will need to be turned in tomorrow at the beginning of class.
Here are the questions:
- Define: A form, a system, a principle, confederacy, democracy, republic, physics, chemistry, biology, matter, energy, mathematics, hydrophilic, hydrophobic, solution, solvent, acid, base, pH.
- List & Describe the 10 Unifying Themes of Biology
- List the taxonomic scheme
- What is the scientific method & why has it been so successful
- List & Describe the four types of chemical bonds.
Chapters 1-6 will need to be read, arrive with questions or I will assume that you understand everything and we'll move onto chapters 7, 8 and 9.
We had some questions in class that were left unanswered...will folks post links or answers as they find them?
Thanks and we'll chat tomorrow! Happy Reading.
Grading & the Final Exam:
All the reading is required
Come to class with questions, if you don’t I’ll assume you understand everything we have covered.
50% of your grade is the final exam
50% of your grade is the homework and I take the median.
Your final exam will be 60 questions answered in 2 hours or less
Questions will be taken from class lecture, homework and all the readings
25% questions on Biochemistry, 25% of the questions on Cell Biology, 25% of the questions on Genetics and 25% of the questions on Plants.
You will be expected to memorize chemical structures, models and cycles
When is something alive?
It must:
Eat, Breathe, Grow and Reproduce
Begs the question….is a virus alive?
Homeostasis-Regulatory mechanisms that maintain an organism’s internal environment within tolerable limits…despite environmental influences.
Page 6 of your book gives a good example of the size comparison of the two cells.
Basic Principles in Biology:
Structure: Work
Form: Function
Surface: Volume
Reductionism – reducing complex systems to simpler components that are more manageable to study. However, there is a dilemma: We cannot fully explain a higher level of order by breaking it down into its parts. The other side of the dilemma is the futility of trying to analyze something without taking it apart!
Cell Theory– Robert Hooke first gave the name cell (1665) in 1839 cells were acknowledged as the universal units of life.
Continuity is based on Heritable Information
Biology has a Vertical Dimension (Size)(Atom to Biosphere) as well as a Horizontal Dimension (Time-4 billion years)
The Story of Biology (Linnaeus)
1735 Linnaeus 2 kingdoms Animals and Plants
1969 5 kingdoms animals, plants, fungi, protists, bacteria
1990 3 domains 4 kingdoms
Darwin’s “Origin of the Species”
2 Main concepts:
Contemporary species arose from a succession of ancestors
He proposed a mechanism of evolutions called Natural Selection
p.13 read a bit of it here.
Evolution is THE core theme of biology.
p. 16 Discovery Science/called….Descriptive Science
The Scientific Method
Observe, Question, Hypothesis, Predict, Test
If yes, support with additional data and tests
If no, Revise your Hypothesis

Here is a link to the sea scorpions we discussed. http://www.sciencecentric.com/news/article.php?q=07112101
Here's a link to wikipedia's explanation of Schrodinger's Cat.
http://en.wikipedia.org/wiki/Schrodinger%27s_cat
If you don't want to read it all, just remember that:
1. "Schrödinger did not wish to promote the idea of dead-and-alive cats as a serious possibility; quite the reverse: the thought experiment serves to illustrate the bizarreness of quantum mechanics and the mathematics necessary to describe quantum states."
2. "Schrödinger's famous thought experiment poses the question: when does a quantum system stop existing as a mixture of states and become one or the other?" Or 'Why does the molecule not form more bands when we are observing it enter through the double slit?'
