Elodea Effect of light on the Rate of Photosynthesis in Elodea Hypothesis: Our hypothesis is the closer to the light or natural light will make the process of photosynthesis faster and increase the amount of bubbles produced in elodea. We had predicted 20 bubbles for natural light, 15 for artificial light , and 10 for dark.
If the elodea is placed in the sun then it will produce more bubbles indicating a higher rate of photosynthesis.

Materials:
1: test tube
2: beaker
3: water ( 250ml water in beaker)
4: area of shade
5: one Elodea sprig
6: Sunlight
7 : Artificial light
8: Darkness/shade

We had to refill the beaker which most likely caused the ratio of baking soda to water to be lowered. We then successfully finished the trial. We learned that light and the conicity of water are all contributing factors to how fast photosynthesis is done. This experiment was done but it did not turn out well. The whole class ended up redoing the experiment and the results above are those of the second experiment. When the first trial occurred, no bubbles were produced for anyone. However, for the second trial, it worked but we had less time. This would be useful if someone wanted to buy an elodea a plant and wanted to maximize its health.

Conclusion. Our hypothesis was supported, the closer to the light or the more natural light will make the process of photosynthesis faster and increase the amount of bubbles produced if the elodea is placed outside then it will produce more bubbles indicating a higher rate of photosynthesis. We had some issues in the way but we did it. Again we had a spill because that actually helped because the first water was giving no bubbles but the second helped and got us

Tn 4351 was originally isolated from bacteroides fragilis [30] . The transposon was successfully introduced into Cytophaga succinicans, Flavobacterium meningosepticum, Flexibacter canadiansis, Flexibacter strain SFI and Sporocytophaga myxococcoides by conjugation [25]. Tn 4351carries two antibiotic resistance gene. One of the codes for resistance to erythromycin and clindamycin which is expressed in bactroides but not in E.Coli. The other gene codes for resistance in tetracycline and is expressed in aerobically grpwn E. coli, but not in anaerobically grpwn E. coli or in bacteroides.

Repeat steps 1-10 for two more trials. Conclusion: 1. I chose to compare temperature and amount of reactants in my experiments. I chose these because I thought they would reveal the the most drastic time differences. I also chose these factors because I had prior knowledge of them before I even started chemistry.

In this three-week long experiment conducted in the Bio 13 Lab, we were able to analyze a single nucleotide polymorphism (SNP) in our own genomic DNA and then determine our genotype at this specific SNP. In week one, we extracted genomic DNA from our cheek cells with swabs and prepared our DNA for PCR (Polymerase Chain Reaction) that would amplify the region with the intended SNP of interest. After one week and after the PCR was run outside of the lab section, the resulting PCR product was purified and treated with restriction enzyme Ahdl in order to prepare for the final analysis of our genotypes. In the third and final week of the project, we analyzed our PCR products by means of agarose gel electrophoresis. By the conclusion of the experiment, we had completed the analysis at the SNP of interest and determined our genotypes for this SNP.

We use Mendelian genetics to study the genetics of C. elegans. C. elegans have very similar genetics structure to humans. C elegans belongs to Phylum Nematode species which is very different from the earthworm. C. elegans is the first eukaryotic organism to have an entire genome sequence. It is very easy and simple to conduct an experiment on C. elegans that’s why the majority of laboratories use this organism.

The null hypothesis, “There is no difference in the concentrations of NaHCO3 and the rate of photosynthetic activity.” is rejected. The alternative hypothesis is supported, that which the greater concentration of NaHCO3, the greater the rate of photosynthesis. Since it was found that the p-value was less than 0.05 in table 1 in all five treatments, this allows the null hypothesis to be rejected. This finding correlates with real life observations of faster rates of oxygen production during lab within the higher concentrations of

5. My hypothesis on the outcomes of each key essential that were being examined in both of my procedures was if the waters temperature gets warmer than before, more carbon dioxide will be created during the time of the reaction, correlated to the temperatures that are slightly lower. My other hypothesis on the outcomes of each key essential that were being examined in both of my procedures was the quicker the Alka-Seltzer tablets disintegrate; the amount of time being wasted for the carbon dioxide getting discharged decreases because this could cause some kind of alteration over the time of the

Elijah Brycth B. Jarlos IX-Argon 1. Multicellularity is a condition of an organism to have multicellular cells. An example of a organism who has multicellular cells are plants, animals, and humans. The main reason of why scientists have a hard time finding a good set of existing organisms to compare. Is neither the first set of organisms which is being compared is dying as fast as the second specimen is being examined or they just can’t find the right species.

Transformation in bacteria usually takes place when a bacterial cell accepts strange DNA and integrates to its own DNA. The transformation normally takes place within plasmids, which are tiny circular DNA molecules that have been separate from its own chromosome. The copies of the same plasmid range from 10 to 200 copies within a cell. These copies of plasmids may multiply when the chromosome replicate or multiply independently. One plasmid has a range of 1,000 to 200,000 base pairs.

The objective of this study was to test the phototactic response of Daphnia when exposed to red (>600 nm) and white light. A 30 x 2 cm clear acrylic mesocosms with a 10 cm counting area was filled with distilled water and 10 Daphnia. We counted the number of Daphnia that traveled to the lit counting area after 10 minutes. There were twice as many Daphnia in the lit counting area for the control (white light) compared to the experimental group (red light). The results showed that red light had a negative effect on the phototaxis of Daphnia.

Because carbon dioxide is absorbed by the plant during photosynthesis less carbon dioxide present in the chamber is a sign that photosynthesis is working. The four lights used for this experiment range across the light spectrum on both sides in order to test a wider variety of wavelengths. All lights will be placed directly on the spinach leaf at the same distance so as not to give any spinach leaf a different light intensity, which could affect the data. This experiment will be able to show which light, ranging across the light spectrum, will allow the Spinach to perform photosynthesis more efficiently.

Research Question: How does the presence of light impact the rate of transpiration in plants? Aim: The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants. Hypothesis: As light intensity increases, the rate of transpiration (water uptake) in a plant increases.
