Paper , Order, or Assignment Requirements

Write a lab report with the information given. In the report there must be:

– An introduction

– Materials & Methods

– Results

– Discussion

Requirements for practical write-up (results/discussion)

1) For the class data plot one of the morphological measurements (height, length, width, weight) against oxygen consumed by the species maintained at 20 oC, and plot by eye a line of best fit for each species (you could put all species on the same plot).

2) Calculate the slopes of the lines (gradients) and use it to compare between the species. Are there differences and if so why?

3) For the snails, using the class data, plot their respiration (oxygen consumed) against incubation temperature and calculate a Q10 for the species.

4) Using the class data calculate a mean respiratory rate per gram of whole animal (wet weight) and convert this to metabolic rate. Is there a difference between the species? How do your metabolic/respiratory rates compare with those in the literature?

5) How could you improve the experiment? What do you think are the biggest sources of error?
