Marine biologist, Igor Vladimir, is conducting research on the 25-40 cm in diameter, Aurelia aurita, commonly known as the moon jellyfish. He is trying to determine how much water is needed to propel the translucent jelly, that is capable of only limited motion, and drifts with the current, even when swimming. Which of the images, A or B, most likely represents a measurement this scientist made? Justify your answer.

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.
