When a jogger starts to run, the rate at which his muscles produce carbon dioxide rises sharply. but the carbon dioxide in his blood rises only slightly before he starts to breathe faster and his heart starts beating more strongly. soon his increased rate of co2 production is balanced by an increased rate of co2 removal. this would be an example of feedback because the jogger's circulatory and respiratory systems are

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.
