The homework problem sets for Biology 3550 will be posted here.

Each problem set will have a total 50 points. At the end of the semester, the the lowest score will be dropped and the problem set average will be calculated from the remaining scorees. This average will represent 30% of the total score for the class.

Problem sets will be accepted up to 5 days after the due date, but the score will be reduced by 10 points for each day that it is late.

- Please be sure to read and follow the guidelines for doing these calculations and submitting your work, and let me know if you have any questions.
- This problem set requires a good deal of calculation and graphing. This work can be done using a spreadsheet program, such as Microsoft Excel, or more specialized software for analying and graphing scientific data, such as SciDAVis. SciDAVis is a free, open-sourch program that is quite capable, though the user interface is not quite so polished as those in some commercial programs. I have written a short tutorial for using SciDAVis, which can downloaded here. Links to the SciDAVis download page can be found in the problem set.

- As originally posted, problem 2d referred to ``page xx'' of the lecture notes. Page xx is page 174. Also, the problem asks for the permeability coefficient in units of cm/s, but the figure referred to shows values in units of m/s. Either is fine, but it will be easier to make the comparison if you use units of m/s. Both of the corrections have been incorporated in the version now available for download.
