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.

In such type of research, where human nuclear material is used for the development of an embryo. So the same policies and concerns are applied as it is about the use of human embryonic stem cell.

Many scientists spent there many years on such research and their work has been standstill because of laws about stem cell research. Some laws ban the use of such an application.

Example: Dickey Amendment.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
