This instrument has made it possible for scientists to observe certain objects and processes that would otherwise never have been seen with the naked eye or a common magnifying glass, because they are more stable and can be built with greater magnifying power, so that smaller structures can be seen and studied. It is used in a wide range of scientific fields, and has contributed to major discoveries in biology, medicine and materials research. What is the instrument?

Some mining processes involve removal of large areas of earths surface in the mined region this practice causes severe environmental damage by allowing which natural process to accelerate in the affected areas? a. precipitation b. erosion c. migration d. condensation

To be or not to be that is da question

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.
