Often symbolized as R0 in disease equations, and pronounced “are not.” This is a crucial number; if R0 is greater than 1, the disease will spread through the population, while if R0 is less than 1, the disease will die out.

The populations he set up would commonly crash and go extinct, with the Didinium eating all the Paramecia and then finding themselves without food.

O’Neil earned a BS in computer science from Northern Michigan University, and later an MS and PhD in the same subject from the University of Notre Dame. His past and current research focuses on bioinformatics. O’Neil has developed and taught several courses in computational biology at both Notre Dame and Oregon State University, where he currently works at the Center for Genome Research and Biocomputing.

For example, if you place a cell in a salty solution, the water in the cell will move out of the cell, causing the cell to shrink. A cell that is 1% salt is placed in a solution that is 3% salt. Place the cubes in the following solutions: Salt water | Tap Water | Distilled Water. How does the cube serve as a model for the cell? (Consider properties it has that is similar to a cell.)

Respirometers will be submerged in a pan of either cold or room temperature water and the rate of respiration will be measured by observing the movement of water into the pipet. Lean your respirometers on the edge of the bath so that the temperature inside the chamber equals the temperature of the bath.

Measure from the bottom of the chin to the bottom of the sternum in centimeters. Place the stethoscope near the sternum and slightly to the left, which is the approximate location of the cardiac sphincter valve. As the subject swallows the water, listen to the stethoscope, you will hear the opening of the valve as a kind of gurgle.
