b) Has no growth factor receptors on its surface

c) Cyclin B is present, the spindle is present, and chromatin is completed condensed

d) Cyclin B is absent, separase is active, and the kinetochore microtubules are shortening

e) The cell can be strongly labeled by adding fluorescent de-oxy-nucleoside triphosphates to its culture medium.
