Influenza can be spread by a) direct transmission (by sneezing thereby mucus entersdirectly into the eyes, nose or mouth of another person b)the airborne route (when aerosols produced by an infected person coughing, sneezing or spitting is inhaled) and through hand-to-eye, hand-to-nose, or hand-to-mouth transmission, either from contaminated surfaces or from direct personal contact .
RESERVOIR: Humans are the principle reservoir of human influenza A viruses. The avian reservoir of influenza A viruses is wild birds,ducks, geese, and shorebirds,

Which of the following best describes why invertebrates isn't considered a scientifically valid word when classifying animals? A. The term invertebrates describes all animals, so is not helpful in classifying organisms within the animal kingdom. B. The term invertebrates is unhelpful because all animals possess some sort of backbone or notochord. C. The term invertebrates classifies animals haphazardly based on a missing characteristic rather than a common one. D. The term invertebrates is too vague, since all animals evolved from...
