franciscana are known to live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat

In testing for the calibration of speed‚ the values in trial 1‚ 2 and 3 were very similar to the adjusted level of speed on the treadmill. The speed level in trial 1 was 1.0 mph‚ which yielded a measured value of 1.06 mi/hr. Trial 2 was 3.0 mph‚ which yielded 3.2 mi/hr and tiral 3 was 4.0 mph‚ which yielded 4.3 mi/hr.

The purpose of this lab was to calibrate a variety of equipment frequently utilized in the Exercise Physiology lab and to become familiar with the operation of the calibrated equipment (Lab manual). The equipment calibrated in the exercise physiology lab was the speed of the Parvo treadmill‚ the incline of the Cosmed treadmill
