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.

How many types of reactions can an enzyme perform?

Your goal is to produce black seeds resistant to mold. So you make the same cross again (between a homozygous black seeded, mold susceptible parent and a homozygous white seeded and mold resistant parent), and, again, advance progeny by SSD to create 100 F10 generation plants. Based on the information you obtained from your first crossing experiment (Question #4), how many F10 plants would you expect to have black seeds and be resistant to mold? Assume that a toxin produced by the mold fungus has been isolated. Only mold resistant seeds will germinate in the presence of the toxin. Could you use this toxin screening procedure to have segregation distortion work in your favor in the F2 generation? Explain your answer. Info from Question 4 a. P Locus (Seed Color): Hypothesis: The null hypothesis (H₀) is that seed color is controlled by alleles at a single locus. Observed Data: Total white seeds: 45 (resistant plants) + 6 (susceptible plants) = 51 Total black seeds: 7 (resistant…
