Arrange the following statements about the Big Bang Theory in chronological order. Hydrogen atoms were forced together under the force of gravity, forming stars and galaxies through nuclear
fusion.
= After one second, the new universe expanded and cooled, forming protons and neutrons.
After several thousand years, cosmic microwave background formed the first light that began to shine in the
universe.
Under extremely hot and dense conditions, a single point called a singularity began to expand, causing a
sudden, massive explosion.
= Electrons became attracted to protons and neutrons, forming hydrogen and helium atoms.

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.
