Earth can behave the same way. But if Earth gets
too hot, the rise in temperature can cause rising
sea levels, major storms and changing climates.
In the summer gardeners can open the

Ozone is made when the sun cooks carbon
monoxide with chemicals in the atmosphere.

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.
