Evidence against the Davson -Danielli Model are all of the following EXCEPT? A. It was unclear how the proteins in the model would permit the cell to change shape
B. Electron micrographs that showed a three layer structure.
C. Membrane proteins are hydrophobic and therefore should not be found where the model placed them.
D. The realization that the lighter and darker areas in the electron micrographs represented phospholipid tails and heads

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
