Find the area under the standard normal curve to the left of z = 1.5.

For the following questions, you will need a periodic table.  Use the one found at this link (don’t worry … Proctorio will be fine if you click this): https://www.fishersci.com/us/en/periodic-table.html   READ CAREFULLY: This question has FOUR parts (A, B, C, and D) and you will need ONE blank sheet of paper (use it wisely).  FOR PARTS A, B, AND C: Write your answers to these parts on your black piece of paper. When you answer each part, write the letter along the left side of the paper and show your solution just under and next to that letter.  SHOW ALL YOUR WORK AS INSTRUCTED IN LABS 1 AND 2. Also, draw a horizontal line across your piece of paper to show where your solution for each part begins and ends. For all atomic weights pulled from the periodic table, round to TWO decimal places.  For all calculations, also round your values and answers to TWO decimal places. Make sure to circle your final answer for each part. When you finish Parts A, B, and C, take a picture of your work with your smartphone and email that image to Dr. Machado at christopher_machado@cuesta.edu.  Make the subject line: Lab 1 Calculations   FOR PART D, TYPE YOUR ANSWER IN THE TEXT BOX BELOW IN COMPLETE SENTENCES!   Part A (6 points) Calculate the number of grams in one mole of cysteine (C3H7NO2S).    Part B (8 points) Magnesium chloride (MgCl2) is a molecule held together by ionic bonds and completely dissociates in solution.  If you are given a MgCl2 solution that has a concentration of 0.5 g/dL, what would be the molarity of that solution?   Part C (8 points) Calculate the osmolarity (in mOsM) of the MgCl2 solution you worked with in the previous question.    Part D (8 points) If you added 5 mL of this solution to a test tube containing 1 mL of human blood and then observed the erythrocytes with a microscope, DESCRIBE what you expect to see in terms of erythrocyte appearance/structure and EXPLAIN HOW that change occurred by comparing this solution to the normal osmolarity of blood.  TYPE YOUR ANSWER IN THE TEXT BOX BELOW, USE COMPLETE SENTENCES AND INCLUDE AS MUCH TECHNICAL TERMINOLOGY AS POSSIBLE!

Approximately ______% of the human body is made up of water.

Study this image carefully.  It shows a microscopic image of various blood cells.      What specific kind of microscope most likely produced this image?  Type the best and most specific answer into the text box below:

  A router with IP address 138.76.29.7 manages a NAT translation table for a private network. The router uses ports starting from 8000. Each time a new connection is needed, it increments by one. For example, if a host in the private network with address 10.0.0.5:5000 sends a message to 132.239.8.45:80 then the entry in the NAT table would be filled in as below. The next time the router will use 8001 as the port to establish a new connection and so on.  All connections are TCP. Complete the NAT Table for the following events:a) 10.0.0.5:5000 sends a message to 132.239.8.45:80 (already filled in)b) 10.0.0.6:5000 sends a message to 74.125.239.33:80    Private Address Private Port External Address External Port Transport Protocol a) 10.0.0.5 5000 132.76.29.7 8000 TCP b) TCP    

If you are using the 10x objective lens with one of the microscopes used for the virtual simulations in Lab 1, what is the total magnification of the image? Type the best answer below in the text box:

When handling body fluids, there are seven Universal Precautions that everyone should follow to keep themself safe and free from infection with bloodborne pathogens.  In the space below, describe ALL SEVEN of these universal precautions using complete sentences.

Proteins in this functional category move polar solutes or ions across the plasma membrane. Type the best answer into the text box below:

Which of the following body fluids DOES NOT require extra safety and handling precautions in the laboratory?

Learning more about enzyme function and modulation was a huge part of Lab 3, so hopefully you absorbed that information.  In the essay space below, briefly describe FOUR distinct “fun facts” or characteristics (1-2 sentences each) that apply to ALL enzymes that you learned in Lab 3 or in our Unit 1 & 2 lectures. As always, write in clear, complete sentences if you expect to earn full points.
