Hi Jing Apology

After I had settled, the first call came through, my phone rang for three times and there was no reaction from the people studying. After some minutes, he called again, and my phone rang for six times, and I did not answer, and the people in the room did not alert me the phone was ringing. Lastly, during the third call, the phone rang again and finally one of the persons alerted me the phone was ringing. After he had told me, I stepped out of the room like I was going to see who was calling and maybe called them back.

3. Follow all procedures in the weekly iLab page, as well as, ElementK’s lab procedures and tips.

mL cylinder to the beaker on the stir plate and empty it into the beaker. Place the pH probe in the beaker and record the pH in the data table. Drag the beaker to the red disposal bucket. Double-click the bottle of NaHCO3 to move it to the Stockroom counter. Repeat steps 5 and 6 for KNO3.

Complete the experiment and save the PDF lab report. Do not answer the questions in the PDF lab report. Use the data in the PDF lab report

To conduct your laboratory exercises, use the Laboratory Manual located under Course Content. Read the introduction and the directions for each exercise/experiment carefully before completing the exercises/experiments and answering the questions.

On my third day of practical placement I was asked to answer a call bell that was activated from Mrs Bee’s bedroom, when I approached her door I gently knocked and waited for an answer. When Mrs Bee answered and gave permission for me to

I apologize for the terribly "late" response to your earlier email. I also received your voice message yesterday. Thank you.

Dress properly and appropriately in the lab. Take all precautions to lessen the measure of any substance that you are presented

4.Measure 35mL of warm water and add them into each of the 4 test tubes at about roughly the same time. It is essential that the water is warm. Do not seal the test tube.

1 ml of water should be added to the first test tube and make a note. In the second test tube, 1 ml of methyl alcohol should be added. In the third test tube, 1 ml of hexane must be added. Lastly, the fourth test tube will be a control.

Submerge the graduated cylinder in the plastic tub so that it is completely filled with water. Hold the open end of the graduated cylinder and move it vertically upside-down where the open end of the graduated cylinder is still submerged in the plastic tub. Clamp the graduated cylinder the ring stand of the lab table to keep it in place. perforate a hole in the top of the rubber cork for the solution container. Cut a straw the length of about four inches. place the straw inside of the rubber cork hole. Set up your timer for two minutes.

Remove foam plug from the inoculate flask and pour it into a cuvette. Incubate it at 37°C and the optical density readings at 600nm every 10-15 mins. Pour into the

1. Number four clean test tubes 1-4. 2. Place 1 ml (or 20 drops) of the following solutions into each tube: water, egg albumin, starch, and chicken broth. 3. Add 3 drops of Buiret reagent to each tube and gently shake

Collect to 2 large beakers both large beakers are to be filled with hot water (labtutor). Then obtain seven conical tubes these will be used to collect the levels of gas, you will also need test tube a stopper and a plastic tube (labtutor). You want to fill the conical tube to at least 50 ml of water (Cressy). Take the four conical tubes filled with water and place two in each beaker, to do this you must invert the tube and cover the release hole as to not lose any water (Cressy). Then place the beakers with the tubes in the bath so they can be at the same temperature as the bath (Cressy). Next mark all of your test tubes in number order to be sure which tube contains what concentrations and pH (Cressy). Having mixed a solution to the specifications of 2.5 ml of glucose in all tubes, 3 ml of yeast in 2 tubes of pH 5, 2 tubes of pH 9, and the single pH 7 tube, the remaining two tubes will contain no yeast as they will be negative controls. Next add 2 ml of pH buffer 3 tubes will receive pH of 5, three will receive a pH of 9 and a single tube of pH 7. Finally add pure water to make sure all test tubes have 10 ml of solution. When making the solutions

The purpose of this lab is to simply determine the absence or presence of the main
