___________________ is the principle of selecting the simplest explanation, which suggests the best phylogenetic tree is the one requiring the fewest character changes.

Based on the phylogenetic tree, which statement is correct?  

To determine the intrapulmonary shunt fraction, the respiratory care practitioner should collect and evaluate the1. CaO2.2. CvO2.3. HCO3.4. CcO2.

When you have completed the exam, be sure to document your work as described in the video posted earlier in our course Canvas site.  Take this moment right before submitting your exam to show your handwritten notes and work to the camera to have all opportunities to earn credit for your work. As shown in the picture below. Once you have completed all questions, documented your work in HonorLock, and submitted the exam, you will need to upload a pdf of the written work in a separate assignment. The link for this is a separate assignment in Canvas.  The file must be sent within ten (10) minutes of the time that you submit the exam.  The work will need to match what you have shown in Honorlock.  More information is available in the announcements in our course canvas site.  All the best. 

A 38-lb cardboard box sits on an oak beam. Determine the maximum bending moment in the beam if the weight is modeled as distributed load w = 1.4615 lb/in. Let a = 40 in. and b = 26 in.

A load of P = 33 N is applied a = 145 mm from the center of a 12 mm bolt. Determine the torque applied to the bolt.

A 36-lb cardboard box sits on an oak beam. Determine the maximum bending moment in the beam if the weight is modeled as distributed load w = 1.3846 lb/in. Let a = 36 in. and b = 26 in.

Determine the magnitude of the largest bending moment (consider both positive and negative peaks) in the beam. Let M = 114 lb·ft, a = 2.9 ft, and b = 8.1 ft. Assume the beam cannot lift off of the supports.
