I have some question regarding this exam. I took the test yesterday where I am and I scored by their scale a 32 (10, 10, 12). However, I have some question that I could not just answer even though I went over them many times. Please, any who has taken this exam, show your compassion and answer this question or elucidate why the answer are what they are. Physical Section: PII. 73-- D was my answer but they say its' B. Please elucidate PIII. 78-- I guessed A and it's correct but don't know why. PIV. 85-- I don't understand this question. Indep. Ques. 89 -- I don't understand how they got D as the answer. 92.-- I have totally forgotten how to convert Normality to molarity. I don't know how they came up with the answer PVII. 105-- B was the answer, please explain why since I believe its A. (Y can't I answer these questions?) 108-- An increase of 50'C (degrees) to my opinion is a lot of degrees and would not allow water to condense. but they indicated that it would condense slowly? I don't get it. PIX. 124--please explain this problem since it confused the heck out of me. PX. 127-- I concluded from the passage that at higher altitudes the energy would be greater but I was wrong. Elucidate please. Same goes for Q130. PXI. 131-- I could not for the life of me figure this one out. The answer was A but I just did not know how to come up with the answer. Q133, 136. Did not understand how to solve, need explaination. Indep. Ques. 138&139. I did there 5 times, but came up with the same answer. I think the answer key is wrong. my answers where B and C respectively. However, in the answer sheet it's C, B. Please I would greatly appreciate your help. Biological section: PIII.159--how did they come up with the answer? PIV.167--What is paten foramen ovale? I have not learned or read this the biology review section. Hence, my answer was wrong. Explaination needed. PVII.184-- I thought that the difference b/w a H and 'Deuterium' is that 'D' is a heavier isotope of Hydrogen. therefore, would 'D' not also give a signal in NMR? Indep. Ques. 197-- Please explain how they came up with the answer. PX.207, 208,209--Same reasoning, I came up with the wrong answer but still do not understand why? BTW, what is AROMATIZATION? Indep. Quest. 216-- what constitutes a right shift in Hb dissociation curve? and I thought that the concentration of EPO in the blood can not increase within a day, it would take more like a couple of days before one reaches high levels of RBC. I know this is a lot of question that I am asking but I urge anyone who has taken this test recently to look over it and give me some insight to these question. Again, I thank you much.
