How do you define homeostasis?

1) actively changing due to an environmental stimulus.

2) taking “raw” materials in turning it into a usable energy.

3) the ability to increase in a size complexity.

4) regulation of bodily functions to stay within a certain range.

To maintain asepsis when administering an injection, all parts of the syringe can be handled except the:

What is the next step in the process after a substrate enters the active site of an enzyme

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.
