Joe's hobby is running marathons and he jogs 10 miles per day to keep in shape. What proportion of fast muscle fibers to slow muscle fibers are found in Joe's leg muscles compared to a sprinter?
O Equal numbers of fast, slow, and intermediate fibers.
Equal numbers of fast and slow fibers:
More fast fibers than slow fibers.
More slow fibers than fast fibers.
Joe's leg muscles are atrophied because Red Bull gives you wings. He flies everywhere so his leg muscles aren't used.

Most animal cell membranes have proteins that pump. ions out of the cell and potassium ions into this

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.
