question 1
1. Your experiment used the decolorization of DCPIP to indirectly measure rates of photosynthesis in the isolated chloroplasts. Why does this work? To answer this, first provide a detailed description of the Linear Electron Flow pathway as it occurs in chloroplasts, and then explain what part of this pathway actually decolorizes DCPIP and why this only occurs when light is shining on the chloroplasts. Feel free to research this before answering. Provide the URL of any source(s) you...

Why does power supply decrease when you add additional resistors in series? (For example, using 3 resistors in series versus 4 resistors in series) I understand that as you increase the number of resistors in series, it increases the equivalent resistance. If the equivalent resistance increases, and the voltage stays the same, then the current decreases (V=IR). Then you can say P=V^2/R, which means that the power decreases, right? But shouldn't the total power be the same as the first...

Does the pH of the solution increase, decrease, or stay the same when you add solid sodium hydrogen oxalate, NaHC2O4 to a dilute aqueous solution of oxalic acid, H2C2O4? Explain your answer using the equation below. H2C2O4 (aq) + H2O (l)⇌ HC2O41– (aq) + H3O+ (aq) 2)Why a solution of sodium chloride and hydrochloric acid cannot act as a buffer? (b) Propose a conjugate acid/base pair which can function as a buffer. 3) (a) Calculate the pH of a buffer...

Chapter 4(microbiology) 1. What are the shapes and arrangements of bacteria cells? 2. Why is it important to be able to identify the shape and arrangement of an unknown bacterial sample? 3. Differentiate between eubacteria and archaebacteria. 4. What are the differences between eukaryotes and prokaryotes? 5. Why would a microbiologist care about those differences? Be specific. 6.

1. What are the similarity and differences between the two
graphs?
2. Does this data support the hypothesis that some reaistance
genes evolved in bacteria that werent exposed to modern
antibiotics? Why or Why Not?
3. Did any antibiotics affect gram-positive and gram- negative
strains very differently? What is a possible explanaition for
this?
4. Do the results of this study give us any insights into how
we might combat antibiotic resistance going foward? If so,
what?

saponification of coconut oil with NaOH
1. What is the nucleophile in this reaction?
hydroxide???
2. Why doesn’t sodium acetate act as soap?
Sodium acetate cannot be used as soap because there is no
non-polar hydrocarbon side component long enough to bind nonpolar
dirt fats or oils. Without this organic component it cannot be used
as soap.???

instead of a carboxylate. Why do detergents work better than soaps
