Sherman is a medical researcher trying to find the causitive agent of a very sick patient with a lung disease. he is fairly sure that the germ causing the illness is not a bacteria, because saliva samples from the patient have not grown any bacteria in the lab. he has also not seen any cells under the lab's basic microscope. all signs seem to be pointing towards the germ being a virus. to know for sure, sherman needs to see the germ under a microscope and determine its 3-dimensional shape. which type of microscope should sherman use to try to see the 3-dimensional shape of a virus in the patient's sample? a) light microscope b) stereomicroscope c) scanning electron microscope d) transmission electron microscope

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
