    when is the cell cycle is likely to be very rapid in an human being, and when it is likely to be relatively slow?

    When part of the body is damaged, cell replication and growth is high because more cells are needed to repair the damage to the tissue. Therefore the cell cycle goes quickly. This is also the case for cancer which is essentially the uncontrolled growth of cells.

    sorry to bug you but can you help with this...
    Explainhow and why you would expect the length of the cell cycle to vary:i)between an early embryo in the first days after fertilisationand a 5-year-old childii)between a 13-year-old student and a 70-year-old adult.

    Well I would say that the length of the cycle in an embryo will be shorter as an embryo is growing therefore it needs quicker cell replication to build up tissue which can from organs. This would lengthen slightly although would still be fairly short at 13 years old because at that stage your body is going through puberty and cells are being replaced. As you get older the cell cycle would increase in length further as you approach 70 when the body begins to deteriorate and cells die.
