1. How does HIV become AIDS?

  • infects T helper by the CD4 receptor and replicates its DNA from RNA using reverse transcriptase, lives in T cell forever
  • infects T helper by the CD4 receptor and replicates its DNA from RNA using RNA polymerase, destroys them when it leaves
  • infects T helper by the CD4 receptor and replicates its DNA from RNA using reverse transcriptase, destroys them when it leaves
  • infects T killer by the by the CD4 receptor and replicates its DNA from RNA using reverse transcriptase, destroys them when it leaves

2. When does TB become active?

  • false - you only have 1 year to live after infection
  • false - it destroys your lungs so you cannot breathe

4. Why do secondary infections occur in HIV/AIDS?

  • reduced T helper cell numbers
  • increased T killer cell numbers
  • reduced T killer cell numbers
  • reduced hormonal secretion
