PLEASE HELP!!!!!!HERE ARE THE QUESTIONS!Olivia is a veterinary parasitologist who is studying a recent outbreak of giardia among beavers in a Colorado river. Since this is the first time she has seen beavers with this type of protozoa, Olivia is attempting to trace where they contracted it. After extensive testing, it is found that human sewage was leaking from a treatment plant nearby. This sewage contained the giardia protozoa, and the beavers picked it up in the nearby waters. Olivia now writes a research paper concerning this case in order to reclassify giardia. After her investigations, into what category is Olivia MOST likely hoping to place these protozoa in?Group of answer choiceszoonosesanthroponosisectoparasiteshelminthsAlthough there is no denying that something killed a third of the population of Ancient Athens, there has been debate as to cause for many years. A historian who lived through it called it The Plague and so for many years, it was accepted to be Yersinia pestis, the same as the bacteria responsible for the Black Death. Recently, though, scientists have become convinced that the outbreak was actually due to typhoid. Given that this opinion of an event that occurred hundreds of years ago has only recently changed, what conclusion can be reached?Group of answer choicesHistorians understand the language of written records more clearly and have discovered that the symptoms match typhoid.Scientists have been able to examine samples of human teeth found in the Athens area and isolated typhoid in the pulp.A recent resurgence of typhoid in the Athens area leads scientists to believe that the climate is perfect for typhoid but not for Yersinia pestis.There is no real reason for the change except that some scientists believe the plague is just a catch all.As the Black Death spread up the Italian peninsula, into France, Germany, and further north, people alive in the 1300s felt that there was little they could do to protect themselves. What option might have been open to England and Scotland that the rest of Europe could not take advantage of?England and Scotland are on an island so they could have closed their shores to ships.England and Scotland had access to scientists who should have found a medicine.England and Scotland have cold, wet environments that should have killed the bacteria.England and Scotland had access to wool that could be used to create masks.
