To find the organism for the project, all I had to do was follow my normal path. I missed the route 35 OH bus from the corner of Olympia Dr. and Authority Way, next to where I had parked in yellow lot 13C. I walked up Olympia Dr. away from the undergraduate admissions offices. I turned right onto East Pleasant St. and headed towards the police station for approximately ten yards. I crossed the street, walked around the chain that crosses the dirt trail and entered the frisbee golf course and walked straight down the trail. I noticed that day that the grounds crew had just mowed down a section of the meadow on my right. The field during the spring and summer months is maintained in such a manner to allow for secondary succession to occur. Paths are mowed to allow people to have access to the area. On my left hand side, my attention turned to an open dried seed pod of the plant species Asclepias Syriaca. There was evidence that something had been eating this milkweed, I was hoping to find a monarch caterpillar somewhere on the plant. I did not find any interesting insects on the plant and I continued on my way. Down past the small little body of water by purple lot 44 D. I crossed Eastman Lane and walked down the hill by Sylvan Residential area.

 

Chem Lab Disscusion

In this lab cyclohexanol was put through dehydration via phosphoric acid and heat. The end product resulted in a 97% yield and 100% purity of synthesised cyclohexene. The purity and identity of the synthesised chemical was determined through GC and IR. The data from the GC shows a relatively short retention time from the  injection point to the large peak. Cyclohexene has a boiling point of 82.146 oC, this correlates to a short retention time. The relative area was calculated by an electronic integrator, which found the sample 100% pure. The results of the IR shows a  strong peak at 3022.45 cm-1 represents stretching between a hydrogen and a carbon which has a double bond to another carbon. A weak peak at 1653 cm-1 represents the stretching of  a carbon double bonded to another carbon. This small or weak peak indicates the presence of only one double bond.

 

Terminal electron acceptor

Once the glucose is catabolized the electrons are transferred to electron carriers. These electrons combine with the electron carriers and they form NADH + H, NADPH + H, FADH2, respectively. The electrons are normally accompanied with hydrogen molecules. Transferring these electrons from the electron carriers to the electron transport chain, creates a proton motive force which fuels the synthesis of ATP. Finally the electrons wind up on the terminal electron acceptor.

The results of the experiment showed as more weights were added the tension in the string increased. With each added weight the speed of the wave increased, this is due from the frequency of the string staying the same and the wavelengths increasing along with the tension and speed of the wave. As the frequency was elevated to create more antinodes the wavelength decreased and the speed of the wave stayed relatively constant through each trial. With each trial increasing the tension resulted in a higher frequency being needed to create the desired number of antinodes from the previous trial

The mornings in my household are normally very busy. From the moment my children awake, getting ready for school and out to the bus is the priority. Breakfast is made,served, eaten, and cleaned up before anybody is dressed. Next making sure my 4th grader is wearing underwear and socks, due to his aversion to these undergarments. Teeth brushing is set up and done by age group youngest to oldest. My daughters hair usually requires my assistance being brushed and put up in a ponytail or braids, etc. Next is making their lunches and putting them in the right lunch bag, and into the right backpack. Out to the bus stop to wait for the bus to arrive and deliver my offspring to the indoctrination of public schools. I then commute to Umass for my classes for the day.

The afternoons and evenings are just as high paced as the mornings, whether it's cleaning, cooking or taking the children to their extra curricular activities.

 

Electricity of life

The profound chemical interactions that take place in all life great or small, one could easily state that chemistry is the electricity of life. In part without an overwhelming number of chemical reactions taking place in one cell alone. Nevermind trillions of cells simultaneously, reducing, adding, and rearranging chemicals and molecules all in the name of maintaining homeostasis of an organism.                                

What is an enzyme? An enzyme is a type of protein, what is a protein made of? Most proteins are made up of polypeptides, sometimes multiple. Polypeptides are chains of amino acids held together by peptide bonds. These amino acids are but molecules, molecules are chemicals held together through chemical interactions. Chemicals are then just atoms, the smallest unit of the foundation of life.

This larvae is 24 mm in length, it contains twelve body segments including the head. The first three pairs of legs have some type of grasping system at the end of the leg used for grasping and forward movement. The next four pairs of legs have cups or suction type parts. These four sets of legs do not release during forward movement until the front three sets of legs can maintain the body weight of the insect, these four legs appear to aid in climbing vertically more than in forward movement. The movement resembles the movement of an energy wave through a medium, starting from the hindquarters moving in the direction of motion up through the insect towards the head.
