When we look at a chemical equation the substances present before a chemical equation are called the
(5)__, and the substances produced afterward are
.
called the (6) _ _. Through the process of a
chemical reaction, we know that mass cannot be
created or destroyed according to the (7) Law.
This is reflected in a chemical equation that is (8)
, where the total amount of (9)
side of the equation equals the total amount on the
other side.

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.
