Lab Questions Unit 4 1. Who were the Poor Clares? Why is it somewhat surprising that they were accomplished musicians? Poor Clares were nuns from a catholic church. It is surprising that they were skillful musicians because they secluded themselves in the church. So people didn’t know what they were doing. When they did come out it shocked everyone. 2. What is a chanson? A chanson is a French song. 3. What is the song "Five Knacks for Ladies" about? What type of song is it? The song is saying that

The Lymphatic System Laszlo Vass‚ Ed.D. Version 42-0024-00-01 Purpose A. What was the purpose of doing this exercise? The purpose of this exercise was to learn about the lymphatic system and its components. We learned about lymph‚ structure and function of lymph nodes‚ T-Cells‚ B-Cells‚ and Macrophages‚ and differentiating between antigens and antibodies. Exercise 1: Microscopic Anatomy of Lymphatic Structures A. Sketch of Reticular Connective Tissue Slide (Lymph Node)

NT1210 Chapter 4 Lab 4.1.1 Why are standards so important for NICs‚ connectors‚ and media? Use your textbook and Internet research to justify your answer. Standards are put in place to make everything work together error free. Because Stability‚ Consistency‚ Minimization of packet errors. 4.1.2 The voltage for registering a bit of 1 on Ethernet can be as low as 2.5 volts or even 1 volt. Why is this so low when the capacity for transmitting electricity on the copper wire is so high? Use your

So in order to get to element 30 you would need to go all the way to the 6p orbitals. In other words‚ every two electrons would necessitate going to a new orbital. 1 | 1s1 | 11 | 1s2 2s2 2p2 3s2 3p2 4s1 | 21 | 1s2 2s2 2p2 3s2 3p2

1. Diffusion and Osmosis‚ June 4‚ 2013 2. Purpose: The purpose of this lab is to help give visual understanding of diffusion which is a solution of high concentration spontaneously (no energy required) moving to an area of low concentration. Also taking a look at osmosis‚ which is the movement of chemicals across the cell membrane. Osmosis requires some type of energy to be put in for this to happen. After these experiments we should have a better idea and visualization of how chemicals transfer
