The following four chemicals commonly found in defined growth media contain all of the necessary atomic macronutrients, namely C, O, N, H, S and P, which microbes require: glucose (C6H12O6), K2HPO4, MgSO4.7H2O, and (NH4)HPO4. Part a. Create a simple diagram to map which growth media chemical contributes atoms to which of the four biological macromolecules (amino acids, polysaccharides, lipids, and ribonucleic acids). Part b. Consider a cell culture broth that originally (before inoculation with cells) contains 5.0 gr/L glucose (C6H12O6), 1.2 gr/L K2HPO4, 0.3 gr/L MgSO4∙7H2O, and 1.0 gr/L (NH4)HPO4. Create a table showing how much of each of the different atoms (C, H, O, K, P, Mg, S, N) are available for incorporation into cell macromolecules (assume 50% of the glucose is catabolized, while the remainder goes for energy (respiration). Express your answers with units of grams of atomic species / liter of culture broth.

When separating your organic and aqueous layer and collecting organic for the final time, is it better to take some of the aqueous layer than the organic layer to ensure collection of all of the organic layer, or to leave some of the organic layers with the aqueous layer to ensure collection of all of the aqueous layer? Explain why.

[Chapter 10] In the figure below, we see the transition from austenite (point a) through the eutectoid point to pearlite (point b). However, other microstructures (bainite, martensite) can also be formed from austenite through the same eutectoid point. How is this possible, given that they are not on the diagram below? 1100 1000 y + FezC 900 800 a a + y 727°C 700 600 FegC 500 a + FezC 400 1.0 2.0 Composition (wt % C) This diagram does not show transformations below 400°c. Austenite must transform to pearlite before it can form bainite or martensite. O Bainite and martensite are non-equilibrium microstructures and this is an equilibrium phase diagram. This is an outdated diagram. Temperature (°C)
Plants absorb several ions and water from soil. For this reason, it is necessary for the soil to have a pH value at the range of 6.0 – 8.0. Again, if the p4 is less than 3.0 or greater than 10, then the beneficial microbes of the soil die. Normally rainwater is slightly acidic, its p# value is 5.5. During thunderstorm nitrogen and oxygen of air react to form nitric oxide, which is oxidized to form nitrogen-dioxide. This nitrogen-dioxide reacts with water vapor and forms nitrous acid and nitric acid. Acid-rain occurs because of it. 2NO2+ H2O → HNO2+HNO3 Examination of soil in a region of Rajshahi revealed that its p" value was 6.43. Nitrogen-dioxide is formed in the air because of thunderstorms, and its concentration is 0.297 ppm. What will be the difference between the p" value of the soil after rain and the lowest standard pH value ?
