Which of the following would be an example of diffusion occurring in the cells of the human body? Q1. The exocytosis of a large protein out of the cell. Q2. A white blood cell engulfing a bacteria cell. Q3. Oxygen molecules moving from oxygen rich air in the lungs to the red blood cells. Q4. The movement of sodium up its concentration gradient in a nerve cell.

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.
