Water is made of two hydrogen atoms and one oxygen atom bonded together. julia is describing how water undergoes a physical change when it boils. she says that the particles shift to be farther apart and that the oxygen and hydrogen separate. she also says that the total mass of the steam is the same as the initial water, and that heat energy was required to cause the change. she finishes her description by saying that the steam can be turned back into water if it is cooled. which is the mistake in her description?

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.
