Donna has observed that her father can control the speed of their grandfather clock by adjusting the
height of the weight on the end of the pendulum. Donna thinks that the pendulum will move faster when
the weight is lowered, and wants to test her idea. Donna gets a stopwatch and measures the time it takes
for the pendulum to swing twenty times when the weight is moved to its lowest position. Donna begins to
move the pendulum up by 1 cm and continues to measure the time for twenty swings of the pendulum.
Donna records her data.

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.
