No, you don't have to.
Did I make your day? ::) :P

Glycogen is a monomer of alpha glucose, yes.
You know about the complementary bases of DNA, right? Adenine binds with Thymine and Cytosine binds with Guanine. (This is for DNA.) The complementary base for Adenine in RNA is Uracil. So accordingly;
Q 21 - B. If you introduce a thymine molecule in the position 'B' the triplet in DNA will be ATC. The complimentary codon of ATC in RNA will be UAG (the stop codon).
Q 22 - D. The mRNA codons for the sickle cell heamoglobin has been listed. Now, you have to find the complementary codon of the tRNA that doesnot help in the making of sickle cell. The codon for tRNA D will be ACG - this is not listed as one of the anti-codons which forms sickle cell heamoglobin.
I hope you get it. ;)

YOU DIIIIIIIIIIIIIIIIIIIID!! BIG TIME!! :D :D :D :D :D
So, in the chapter gas exchange, we're supposed to know:
-the adaptations of the alveoli as gaseous exchange surface
-inhalation and exhalation [what happens during them]
-definitions like tidal volume, residual volume, vital capacity, etc.
-tobacco smoke and COPD and the effect of nicotine, CO, etc.
that's it?
& what about 'epidemiological evidence' whether in this chapter or in the cardiovascular diseases, do we need to know that as well, as in would we be asked to provide such evidence?

Yes, you do need to know about that. You wont be asked to provide evidence but I think, the questions will as such the evidences will be provided and questions will be asked based on them. Get my point?
