    A sample of healthy human cells contains 4 cells. After they were allowed to divide 5 times using the same type of cell division, there were 128 cells in the sample.
    Assuming that no mutations occur, which two of the following statements are correct?

    1 All the cells would have the same number of chromosomes.
    2 The cells were gametes.
    3 The cells would be clones of the original cells.
    4 This type of cell division is called meiosis.
    A. 1 and 2 only
    B. 1 and 3 only
    C. 1 and 4 only
    D. 2 and 3 only
    E. 2 and 4 only

    First we have to determine whether the underwent mitosis or meiosis. We do this by seeing which process will give 128 cells after it happens 5 times. In the case of mitosis we have 4 cells then 8 then 16 then 32 then 64 and then 128. So we have mitosis. Therefore, the cells created are identical to the initial cells and statements 1 and 3 are correct.

    The answer is B.
