A10-7 is performed on a culture of bacteria in order to perform viable plate counts. from the dilution, *0.1 ml* of solution is plated on solid media, and 66 colonies of bacteria grow on the plate. assuming each colony came from a single bacterium, how many bacteria are in a single ml of the original culture?

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.
