The last two times that i was sick, my neck really hurt/ached and if i touched it, it felt kinda like it was bruised (and i know it wasn't bruised). i was just wondering if there is a reason for this and if this is normal because it seems pretty weird to me. any ideas why it happens?

Which step in healthy decision making requires you to look at the decision you made and determined whether different actions would have produced different results

Me with this i need to get the answer quickly.

Which of the following best reflects what we know about how the flu virus moves between species? a) the flu virus in a pig is mutated and replicated in alternate arrangements so that humans who eat the pig products can be infected.b) a flu virus from a human epidemic or pandemic infects birds; the birds replicate the virus differently and then pass it back to humans.c) an influenza virus gains new sequences of dna from another virus, such as a herpesvirus; this enables it to be transmitted to a human host.d) an animal such as a pig is infected with more than one virus, genetic recombination occurs, the new virus mutates, the virus is passed to a new species such as a bird, and the virus mutates again and can now be transmitted to humans.
