A student put a half teaspoon of yeast in each of three
different balloons. Then he added a quarter cup of water to each balloon. Each balloon received water of a different temperature: hot, warm, and cold. After adding the water, the student tied off the end of each balloon to seal it shut. The yeast began to produce bubbles of gas inside the balloons. After 20 minutes, the student measured the circumference of each balloon to determine how much it had grown in size.

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.
