Question

Can anyone put these in the correct sequence, my instuctor an i disagree. Here goes:1.HIV attaches to CD4 receptor site 2. opportunistic infection occurs 3. infected cell replicates itself millions of times 4. T helper cells fail to activate phagocytes 5. Immune system unable to respond effectively. What order do these go?

Answer 1

1. HIV attaches to CD4 receptor site.
2. T helper cells fail to activate phagocytosis.
3. Infected cell replicates itself millions of times.
4. Immune system unable to respond effectively.
5. Opportunistic infection occurs.

Dare I ask, is that what you had or what your instructor says?

Answer 2

I put it the same way you did, but instructor put #3 then # 2, im challenging the question. hopefully she see it my way

Answer 3

OK, if that's the case I think there has been a misprint.

It should say, virus inside infected cell repicates itself millions of times. Not infected cell replicates itself millions of times. Then and only then do you have T cell fails to activate phagocytosis.

That makes much more sense.
