In habitat A, a late-successional plant grows at a rate of 0.5cm per day when surrounded by early successional plants. If the early-successional plants are removed experimentally, the late-successional plants are observed to grow at a rate of 0.9 cm per day. In habitat B, the same late-successional plant grows at a rate of 0.5 cm per day when surrounded by early-successional plants. If the early-successional plants are removed experimentally, the late-successional plants grow at a rate of 0.3 cm per day. For each habitat, which successional model best describes the system

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.
