ACTIVITY 1 Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. __The size and the concentration. ___ 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? __ The molecules were to large to go through. My results matched._ 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your

1) Make a graph of resting heart rates from Activity 1. Provide a physiological explanation for fluctuations in resting heart rate over time. Discuss a couple of extrinsic factors that influence the autonomic nervous regulation of resting heart rate. The resting heart rate fluctuates over time because it is under control of the autonomic nervous system and the fluctuations are a result of the sympathetic and parasympathetic systems trying to balance each other out. There are many reasons

This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between 1 and 6

Name: NT1210 Lab 6.4: WLAN Placement Exercise 6.4.1 There are three main types of antennas that can be used for WLAN APs: directional‚ omnidirectional‚ and right-angle. Describe each of these antenna types. You can get more powerful antennas that can broadcast longer distances. Why would these antennas be limited in use for standard WLAN placement in a home? An omnidirectional antenna radiates transmissions out and receives transmissions in from all directions‚ although not equally in all directions
