I don't entirely understand your question, but the phases of mitosis are (in order): Prophase, Metaphase, Anaphase, Telophase
This statement is true. To be more specific, the calcium ions bind to the troponin, which are attached to the protein tropomyosin. The tropomyosin then to shifts to expose the actin filaments to which myosin heads need to bind to produce contraction.
Anything that doesn't have to to with the living organisms or life in that sphere such as a rock or the dirt. It would help if you posted options. :) hope this helped
