Anh Le 10SC Bio Where are the stomata? Aim: To determine where the water comes out of the leaf or not which would explain where the stomata are located. If yes, water does come out then where? Variables: Independent: Side where the Vaseline is applied to: Where you place the vaseline if you apply it or not will determine if the water vapor will escape or not will enable you to measure the weight change. Dependent: Weight of the leaves: First of all you find the original weight of the leaves.
To determine if hyphae grow at the same rate, graph the results of table 2 and compare the slopes of the 3 hyphae from the slide preparations. 11. To determine if mycalolide B affects fungal tip growth and nuclear position repeat all the steps except in step 2 need to add mycalolide B and let it incubate for 10 minutes. Make sure to label the slides with the

Make sure to use the same amount of weed killer in each box. Continue watering the boxer and record data on how much the weeds have grown and or decreased. Analysis Possible results to keep an eye out for would be dead grass, weeds, and the growth of molds. Conclusion To determine whether or not the

Water from a variety of sources that receive precipitation is being sampled. Using a pH meter, the pH of water samples is being measured. In the first approach using titration methods in combination with pH measurement, the volumes of sulfuric acid needed for reaching two different pH levels are being measured. Difference in the volume of sulfuric acid used, is an equivalent for the amount of CaCO3 expressed in grams per (gL-1) in the analyte. Therefore the alkalinity of water samples is being calculated.
At the beginning of the first paragraph in the left column, insert the sunflower picture named “support_NP_W10_T4_CP1a_Sunflower.JPG” (available from the SAM Web site). Rotate the image using the Rotate Right 90º option. Flip the image horizontally. 11. Resize the photo so that it is 1.5 inches wide if necessary, and then remove the green background, retaining only the image of the sunflower.

Ally Emerson Lab Report H. Chem. Period 3 1-11-15 How does mixing distilled water, iron, and copper (II) sulfate and then boiling the mixture help us determine the theoretical and percent yield of copper after the chemical reaction? Partner: Naomi Purpose: To determine the theoretical and percent yield of copper after a chemical reaction between distilled water, iron, and copper (II) sulfate. Hypothesis: There will be around 2 grams of copper left, which will equal a 89% yield. Materials: scale, filter paper, weighing paper, distilled water, copper (II) sulfate, iron, beaker, tongs, drip, and a funnel.
Samples were taken where red arrow is located. The sampling procedure was repeated on November 13th, 2014, at Providence River. The samples were taken in the same exact manner as the week before. All of the samples were then taken into the lab to be analyzed. The analysis was done by identifying the first 100 organisms found in each sample and recording the results in an excel spreadsheet.
