Going from point A to Point B in a single line
Ex. Past Future
Moving at a constant pace in circles continuously repeating
Ex. Calendar, Seasons
Multiple cycles (Beg. End, Beg. End etc.)
*Both the Greco-Roman and Judeo Christian believed in this cycle
-Golden Age (Beginning- Adam & Eve etc.)
-Degeneration (Eve making Adam eat apple)
from a neighboring island arrived. These larger finches could drive away the native medium ground finches and would eat all the large nuts. Over the period of study, the medium ground finches of Daphne island were found to have developed smaller beaks more suited to the smaller nuts, ignored by the invading larger finches. This is a classic study in evolutionary biology.

Exam 3 Micro Study Guide
Chapter 14: Disease / Epidemiology
Microbiota (the host)
Transient Microbiota may be present for days, weeks, or months
Normal Microbiota (normal flora) permanently colonize the host becoming resident Microbiota
Symbiosis is the relationship between normal Microbiota and the host
Commensalism: One organism is benefited
Mutualism: both organisms benefit
Parasitism: one organism is benefited at the expense of the other
Some normal Microbiota are opportunistic…
• Atom: the smallest part of an element that retains its property
• Molecule: (can be an element or a compound) 2 or more atoms chemically bonded together- smallest it can be divided and retain essential chemical properties
• Element: Pure substances that cannot be broken down chemically different/smaller substances
• Compound: when elements combine chemically
1st and 2nd Laws of Thermodynamics:
Law of Conservation Energy: Energy cannot be created nor destroyed, only changed in form. The…
biology - the scientific study of life
biosphere - all environments on earth that support life
ecosystem - all organisms living in a particular area
community - entire array of organisms in an ecosystem
population - all individuals of a particular species living in an area
organism - individual living thing
organ system - consists of several organs that cooperate in a specific function
organ - made of several different tissues

Midterm Study Guide
Is reproduction necessary for the continued life of a single organism?
Living things are based on a universal genetic code.
Q: What is that code?
A: In terms of genetic code- what’s the difference between organisms that reproduce asexually and those that reproduce sexually?
Q: How do we get bacteria that are resistant to anti-biotic.
A: They evolve.
Q: Living things grow and develop:
A: Cells become specialized for different functions…
KEY NOTES CHAP 7
* The first view of cells: Robert Hooke’s drawing from 1665 (30X microscope)
* Cells are dynamic.
1. Thousands of chemical reactions occur each second within cells
2. molecules constantly enter and exit across the plasma membrane
3. cell products are shipped along protein fibers
4. elements of the cell’s internal skeleton grow and shrink.
* Electron micrograph(higher resolution than Light microscope)
* fact that it was easily stained with early…
CELL THEORY AND MEMBRANES
Hooke: First to look at cells (dead cork)
Leevwenhoek: first to look at living cells (pond water) Determined organisms live in peoples’ mouths.
Dutrochet: “All things are made of cells” had no/little support
Brown: Discovered the nucleus of cells
Dujardin: Discovered the cytoplasm
Schleiden: all plants are made up of cells
Schwann: all animals are made of cells
Virchow: all cells come from previous living cells
1. A cell is the smallest…
