4) The invertebrates found are color-coded according to their sensitivity to pollution. For example, species that can live in (tolerate) high levels of pollution are shown in red and blue. Finding indicator species at a site shows scientists there is no pollution in the water. Knowing this, which site has better water quality? a) Lowry Park Boat Ramp b) Hillsborough River State Park

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.
