Lab Report On The Lab

When the pH is not at its optimum, the differing pH's will disrupt the bonding between the R groups of the amino acid causing its structure and the shape of the activation site to change

The results of this experiment ended up being very conclusive and not positively or negatively surprising. The data and results collected we what we had expected more importantly the ones on the X-Gal plates where the colonies were above 100. Both the stains of E. Coli grew colonies when they were in the LB. When the ampicillin was present the cells did not grow even with the X-gal. The transformed cells on the other hand grew when the ampicillin was there. When the X-gal and AMP were present the transformed cells grew and had a blue tint, which is why we call it the pBlu lab. (duh)

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

In the LB (pGLO negative), it is expected to not see any colonies growing. As a result of this experiment, it shown any growth colonies but this only had shown a large number of white, circular colonies that were found across the surface of the agar. In the LB/Amp (pGLO negative), it is expected to see any growth colonies. In the experiment, the resulted was no growth colonies because this has Ampicillin and no pGLO. Now, the LB/Amp (pGLO positive), it is expected to have growth colonies in the agar plate. As a result, it was shown growth colonies in the agar plate because has positive pGLO regardless having Ampicillin. In the other hand, both positive pGLO have the same components but in one plate was added Arabinose. The LB/Amp/Ara (pGLO

This is important in the medical field because identification of unknown bacteria can help treat a patient by knowing the contributing source of a disease. Also knowledge of different bacteria helped others make antibiotics used today. This lab was completed by using the methods learned thus far in identification of bacteria.

Make three exposures using given technical factors on a phantom knee in PA position . Include saline bags in exposures 1 and 2 to demonstrate patient soft tissue thickness.

**What I want you to pay attention to in the above example is that I have extracted information from the lab manual and condensed it into a logical paragraph that explains some of the important concepts. Notice that I did not include any "fluff" (useless information to make my introduction longer.) Remember that there is no minimum length for any of your sections so you don’t have to worry about adding in anything that is not pertinent to the lab (unless you actually want to include some background info to help develop your ideas.)

The experiments conducted for this lab report focused on water contamination and filtration. Experiment 1 was effects of groundwater contamination. Oil, vinegar, and laundry detergent were added to clean water with no means of filtration. The clean water was found to be contaminated. A filtration system consisting of cheesecloth and 60 ml of soil was created and the contaminated samples were filtered through it. The soil and cheese cloth did not affectively filter the contaminants. Experiment 2 focused on

The objective of this experiment was to identify two unknown bacteria from a mixed culture. Which was done by using the aseptic technique which was very important to avoid any contamination and keeping the workspace clean while culturing bacteria for different tests. To start, I chose a tube which had a solution of mixed culture. I used the flame to sterilize the inoculating loop and dipped it into the tube and streaked for isolation on 2 TSA plates and placed them in an incubator at 37 for 24 hours. Next day I observed the growth of 2 different types of colonies one for each unknown on the two plates. So I picked the best one and labeled it as master plate and discarded the other plate. From the master plate, I subcultured each type of colony

October 17, 18, and 19, samples were collected from multiple sites along the BSR. The class was split into groups, and samples were collected from seven separate locations along the river and WWTP. There was also a sample collected by the S which is located between sites four and five. For each of these sites, there were ten groups from other labs that also collected a sample from the BSR. At site two of the river, the location included multiple sources of possible contamination. A drainage site was located 200 yards upstream, along with a small PVC drainage pipe next to the collection site. Not only was there drainage running into the river, the site was under a bridge, and contained other trash scattered throughout the area. The

This experiment is about bacterial growth. We will demonstrate a bacterial growth curve using a closed system. Bacterial growth usually takes up to 12-24 hours to get an accurate result so we will be monitoring this growth between two classes. We also used different methods to determine bacterial growth as well as a few different calculations. One way of receiving data is by using a spectrophotometer where we will record the absorption at a given time to create the bacterial growth curve. We also used the plate count method after performing a serial dilution to calculate the actual cell density at different times given. By using this method we can count the population number of the same given and see the maximum cell density

In this lab experiment, students had to create a growth curve for E. coli. The E. coli growth curve would illustrate the progression of the population of E. coli a set time period. In this case, the growth curve depicted the population of E. coli over a 12-hour period. The growth curve for E. coli was created from the absorbance levels, the optical density(OD), recorded from the spectrophotometer.

In this bacteria growth lab, students from Mrs. Bronson’s biology class collected bacteria samples from around the school and grew them in petri dishes filled with agar which were prepared one day before in advance with the expectation that after one week, distinct bacterial colonies will grow larger in numbers so that the human can see them. These single-celled prokaryotes were grown on agar as it is easy to culture and grow bacterial colonies in nutrient agar, a gelatin-like substance with a semi solid surface on which bacteria can grow and reproduce quickly while consuming added nutrients in the agar mixture. The petri dishes were then incubated for a period of one week, so that students can examine the significant bacterial growth and compare observations of various samples collected by students.
