Expert Solution & Answer

Explanation of Solution

The clearing of the forest cover of Hubbard Brook in the year 1965 and 1966 lead to a runoff of a large amount of water which was about 40% of the water present in the valley. The amount of nutrient that was eroded also increased. The change in the quantity of nitrogen in the disturbed valley was different from the undisturbed part of the valley. The undisturbed area has accumulated about 5kg per hectare of nitrate per year but in two years the runoff leads to a loss of about 53 kg of nitrate per year. The nitrate concentration in the stream water also rapidly increased due to runoff. The fertility of the soil in the valley decreased strikingly.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours. (Example: If percent is 20%, then Time in Hours = .2 * 24 = 4.8) Record your data in Data…
