- As water cools below 4°C, it expands and becomes less dense. Why is this beneficial to organisms living in a lake during a cold winter?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.Explain how these factors: the size of bioaerosol, inspiratory flow rate, flow pattern, inhaled volume, respiratory rate influence the respiratory degration of bioaerosols.

Assume that the temperature is 37°C Round to the nearest 0.1Using supporting calculations, determine the energy and cost (carbon) savingsassociated with the following biological nitrogen removal strategy: Partial nitrification (oxidation of all the influent ammonia to nitrite) and partialdenitrification (reduction of produced nitrite to nitrogen gas)

Indicate which would be the expected order of elution from first eluted to last.Define water activity and briefly describe how it can be determined. Why is it difficult for microorganisms to grow at low aw values?In one final experiment, you add all the necessary components and program the thermocycler to cycle under the following temperatures Denaturation 95 degrees, 30 seconds, Annealing 65 degrees, 30 seconds, Elongation 68 degrees 30 seconds You find out that the third time's the charm, but now you have many small incomplete fragments instead. What happened and how did you fix it?
