Answer 2

I am an MD. Mr Premier is all wrong. For one thing, there are seven questions and he gave eight answers(?!). I believe the correct answers are: B,C,A,A,A,D,A. However, I must argue with several of the questions. In question 3, you may well carry antibodies to type B, but there is no assurance that you will. The correct answer to question 5 is tetany, not Tetanus. Tetanus is actually a disease that is caused by Clostridium Tetani bacteria. In question 6, the most abundant plasma proteins are the globulins, but they are not a single type of protein. The most abundant single protein is albumen. In question 7, Angiotensin II also increases aldosterone production and secretion, which is not mentioned in the correct answer, making this answer incomplete.
