Which experiments led to changes to the original cell theory? a: experiments that showed that blood cells transport gases, waste, and nutrients throughout the body b: experiments that showed that all cells are similar in how they metabolize and in their composition c: experiments that transplanted synthetic chromosomes into bacterial cells to create a new species d: experiments that established the existence of single-celled organisms and microbes

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.
