- Every day, Sulfur surface coverage doubles in a pond On Day 30, the surface of the pond is completly covered. What was the first day that greater than 30% of the pond was covered?Mukul conducted an experiment in the Green House of University of Delhi. He filled 10 kg of sterilized and unsterilized rhizospheric soils collected from the Wheat farm in pot X and pot Y respectively. 20 g of rice crop straw was added in both these pots and they were watered daily to the field capacity with equal and measured amount of water. After one-month period, a significant decrease in the soil pH of pot B was observed. Speculate the possible reason behind this observation. Thanks in advance ?Pls solve this question asap with proper explnantion, STRICTLY TO BE HANDWRITTEN
- (Please give clear handwritten answer) A medium containing an abundance of substrate was seeded with 20 mg/L VSS of an active mixed culture. After 8.0 hours, the VSS concentration was measured at 590 mg/L. Data indicate that there was a lag time of 0.5 hours. Assuming log growth, what is the average generation time of this culture?Two microorganisms that use naphthalene as a food source have the same Umax but different Ks values for naphthalene. If both types of microorganisms are inoculated at the same cell density into a liquid culture containing naphthalene as the sole carbon source (i.e. the only food source), which microorganism will outcompete the other: the one with the higher Ks or the one with the lower Ks. Why?.Thermal images are photographs of the heat emittedby an object. Researchers have used thermal imaging ofplants to isolate mutants that overproduce abscisic acid.Suggest a reason why they are warmer than wild-typeplants under conditions that are normally nonstressful.
- In UV/Visible spectrophotometer analysis for a multicomponent system, there are only two dyes used in the mixture, the two proportions should be totalled to 1.0. but on finding You got 0.6 in total. Explain the reasons for the difference.You are applying a 15-inch band of herbicide over 30-inch soybean rows and have 10 acres of soybeans left to spray.

How many quarts of herbicide are needed to complete the application?In a photosynthetic investigation, a student measured the following pH of the stroma and the inner thylakoid compartments of spinach leaf cells at the conclusion of the experiment. Source of Fluid pH (mean) Standard Error of Mean (SEM) Stroma 8.2 0.75 Inner compartment of thylakoid 5.6 0.35 b. Construct an appropriately labeled graph to illustrate the sample means of the two locations to within 95% confidence (i.e. sample mean + 2 SEM).
- Order of Draw: Match the following additives found in the rows to their corresponding use/purpose in the columnsA biofilm is a layer-like aggregation of microscopic particles and organisms attached to a solid surface. Nutrients must diffuse through the layer in order to sustain the organisms throughout the film. A typical biofilm thickness is 0.01 cm and the diffusivity of the nutrients in the biofilm layer is estimated as 0.8 cm^2/day. A. Assume that the concentration in the bulk fluid and at the solid surface are both constant. Derive a general expression for the steady-state concentration profile within the biofilm. (hint: recall that Fick's second law of diffusion can be used to solve for concentration profiles.) B. If the bulk and surface concentrations are 3.2 mg/liter and 0.25 mg/liter respectively,what is the expression for the concentration profile in this specific case? C. Calculate the flux of nutrients at the solid surface and at the interface with the bulk fluid. D. Explain the reasonableness of your answer.The authors of this paper also tested another minimal media (Media C) which is exactly the same as Media B except that the pH is 7.4 instead of 7.1. Which media components would be different in Media C? For each component that is different, state if will be larger or smaller than the amount in Media B.
