Ap Bio Lab 2.1 Lab Report

Purpose: What is the purpose of this exercise? Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken. To understand the structure and function of multipolar neuron,unipolar and bipolar neurons. Also to identify the structures of a nerve. There are no safety concerns for this lab.

Based on the 1H NMR spectrum that was collected, a few things can be determined. Based on deshielding and electronegativity, the peak that occurs around 4.7ppm is associated with the O-ethylsaccharin product and the peak at 3.8 ppm is associated with the N-ethylsaccharin product. Based on the height ration, the N-ethylsaccharin product is the more prevalent result.

A) Describe in your own words, in as much detail as you can, the anaerobic metabolism of glucose to pyruvate. B) Draw this pathway (by hand), indicating all substrates, enzymes, cofactors and products. (You do not need to include reaction mechanisms.)

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.

17.At home, the student is cooking with butter and lard. While the fats sit on the counter, it is noticed that the butter begins to melt, but the lard doesn't. Based on what the student knows about fats, which product most likely contains the most

Observation: no bugs were found except small, black, gnats were all close to the ground.

The major storage polysaccharide in plants is starch. These molecules would be found in abundance in the stroma in the plant tubers where it is found as granules. Glucose is stored mainly in the form of starch granules, in plastids like chloroplasts and amyloplasts. Plant starch starts out as glucose, but glucose is very hard for plants to store, so it is converted to starch through polymerization. Amyoplasts turn the glucose into starch and move it to the stroma, and in tubers the stroma is a place to store the food (starch), and when plants need the energy in the starch, it converts the starch back into glucose.

Hypothesis correct?: Yes and no. The tap water did soak up the color best, however the plants in soft water and the reverse osmosis

1.) My hypothesis that the insects would be most repelled by the lemon plant extract was not supported. Our key findings in the experiment do not support my hypothesis because the lemon had a 60% repulsion response and was the second most repulsive behind orange with a 70% repulsion response. Although the Earthworms were repelled by the lemon plant extract, they were more so repelled by the orange plant extract. 2.)

2. (5 pts) List and explain the names and affiliations of the various characters/stakeholders in this story – I’m looking for us to use the story to map out the complexities that are generally associated with solving public health puzzles – the stakeholders you list and explain here should apply to many of the cases we consider going forward.

This study was performed in order to gain more knowledge on mitosis and meiosis. This lab was done by observing mitosis in plant and animal cells, comparing the relative lengths of the stages of mitosis in onion root tip cells, stimulating the stages of meiosis, observing evidence of crossing-over in meiosis using Sordaria fimicola, and estimating the distance of a gene locus from its centromere. Mitosis is the scientific term for nuclear cell division, where the nucleus of the cell divides, resulting in two sets of identical chromosomes. Mitosis is accompanied by cytokinesis in which the end result is two completely separate cells called daughter cells. There are four phases of mitosis: prophase, metaphase, anaphase and

The first agarose gel provided insight into whether or not Zassy’s genomic DNA had been cut by the Sal I HF (NEB) restriction enzyme. As seen in Figure 1, Zassy’s cut DNA, in lane 3 left clear fragments between the 3 kb and 0.5 kb areas. Zassy’s uncut DNA, in lane 2, left a clear and bright band above the 10 kb marker. Therefore, the gel confirmed that Zassy’s DNA was successfully cut with Sal I because there was a significant difference the cut and uncut DNA that was run through the gel. There was an additional lane of cut DNA because another student adopted Zassy in the early stages of this experiment. Nevertheless, the clear distinction between lanes 2 and 3 allowed the experiment to continue on to purification of the DNA.

Everyday society passes by minute details with no regard what so ever for the magnificent organism that functions to produce an essential gas vital for the human life. This magnificent organism are the various leaves one may find in backyards to parks to school. Although they are small and disregarded, they have various forms that are each unique to certain regions. Therefore the purpose of the lab is to explore the different types of leaves in different environment with different climates. Its significance is that we individual can observe how various factors affect the leaves in a specific area. The experiment will take place at Fullerton’s local university, California State University Fullerton. They possess an incredible arboretum that

Organisms cannot depend solely on spontaneous reactions for the production of materials because they occur slowly and are not responsive to the organism's needs (Martineau, Dean, et al, Laboratory Manual, 43). In order to speed up the reaction process, cells use enzymes as biological catalysts. Enzymes are able to speed up the reaction through lowering activation energy. Additionally, enzymes facilitate reactions without being consumed (manual,43). Each enzyme acts on a specific molecule or set of molecules referred to as the enzyme's substrate and the results of this reaction are called products (manual 43). As a result, enzymes promote a reaction so that substrates are converted into products on a faster pace (manual 43). Most enzymes are proteins whose structure is determined by its sequence of its amino acids. Enzymes are designed to function the best under physiological conditions of PH and temperature. Any change of these variables that change the conformation of the enzyme will destroy or enhance enzyme activity(manual, 43).
