Students do an experiment to show static charge. They set a piece of clear plastic on blocks above a desk. They put
some dry rice cereal under the plastic. The students rub the plastic with a wool cloth to cause a static charge. This makes the
cereal jump, as it is attracted to the plastic.
Pane of clear plastic
Wooden block
Cereal
Desk
The students try other materials. They rub each material against the plastic to see if it creates a static charge that makes the cereal jump.
Which material will most likely produce the same result as the wool cloth?
O A a brass key
O B. a wood block
C. an iron magnet
OD. a piece of nylon

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.
