The Tubes

to identify the extent of the damage to his abdominal area, they would need to operate. To prevent post-operative complications, tubes were inserted into the patient. Upon waking up from surgery, Mr. Howell became uncooperative, by trying to pull out the tube, due to his mental state. On October 15th, his abdomen became distended due to the surgery. A second tube was inserted to help resolve the abdominal complication with the intent…

the xylem tube. An embolism is the blocking of a xylem tube by an air pocket. If a tree experiences cavitation it will eventually starve to death from lack of water. Cavitation and embolism are similar concepts. Both are the blocking of the xylem with air or water vapor that prevents the tree from drinking. Cavitation and embolism can occur is a single xylem tube or many at once (Trifilo, Barbera, Raimondo 2014). When the drought becomes severe, cavitation will occur in all the xylem tubes,…

as the ending volume. Each reagent was added to the tubes carefully. The tubes were placed in the PCR machine and ran on a 0.7% agarose gel. The samples were observed. Tube three had the biggest band that implied that it had the highest concentration in the MgCl2. Introduction PCR (polymerase chain reaction) is a technique enabling researchers to produce millions of copies of a specific DNA sequence in approximately 2 hours in a small test tube. This…

The results from the experiment generally show the trials with full light intensity to have produced more oxygen, showing the elodea samples to have photosynthesised more than the lower light intensity trials. Trials 1 and 2 were in water bath 1 with full light intensity, whereas Trials 3 and 4 were in water bath 2, with lower light intensity. Experimental error caused the trials with the lower light intensity to be disrupted, and no data was collected for these trials on Day 8 of the experiment…

The second time I went tubing I was at big bear lake for the second time that month to go tubing. I nervously walked down the pier and to the boat. Me, Chen, Kayla, and Noah were all going tubing together. We all got on the zipper up life jackets and got on the boat. As we sat down, the boat started to make rumbly grumbly noises of the engine turning on. I was nervous because my last tubing experience had been a total disaster. I thought back about it and then suddenly I flashed back to that…

kill”. Demonstrators picketed the court house and death threats were made toward Judge George Greer. They viewed that withholding tube feeding and hydration from Terri was killing her. It was viewed not only as unconstitutional but immoral. In their eyes Terri’s wishes did not matter. At this time the Florida courts would not rehear the case and Terri’s feeding tube was…

µL mixed bacterial suspension were removed from the tube labeled “C” and the lid from the control was removed, as well as the bacteria dispensed onto the agar. A cell spreader was dipped in ethanol and was used to spread the bacteria evenly along the agar surface. The transfer of 130 µL of bacterial suspensions from the “lux” tube was placed into the “lux” plate and the cells were spread onto the agar surface once again. The cells in the “NP” tubes were plated onto 2 plates labeled “NP” and the…

use of FDA had an average of 26% of pollen was viable out of total pollen grains. Self-pollinated styles collected after 24 hours showed presence of pollen and pollen tubes germinating. One outcrossed style collected after 24 hours showed presence of pollen germinating and the other style was lost. It was not clear if pollen tubes were germinating in the outcrossed style. One self-pollinated style collected after 72 hours showed the presence of pollen germinating and the other…

shaped curve (similar to theoretical data – See Background Information for reference) which can be seen as an effect of the specific pH on the catalase enzyme. This identified trend can also be supported by the raw data values of the control test tubes as it demonstrated that the hydrogen peroxide and the pH buffer solution did not affect the boiling chips (which did not contain the enzyme catalase) and it was from the presence of catalase within the potato discs which caused the resulting froth…

Introduction: The purpose of the tests (culture media, motility, enzymes, etc.) we preform on the numerous bacteria in lab is to show any biological or chemical characteristics of the bacteria that may help it survive or adapt in the wild, how it may be useful or hazardous to humans, and use as general knowledge to differentiate bacteria from each other. In the Culture Media test we can use solid and liquid media to grow multiple bacteria in lab. It can help us determine what processes the…
