stages of a cell cycle. Arrange the description in the
correct sequence of events. (Record all four digits of your
answer.) - Chromatids separate and move to opposite poles.

Use the following information to answer questions 3 to 6.A student observed three different areas in the mitotic region
in an onion root tip. She counted the number of cells that were
at each stage of the cell cycle at the time the root was killed
and mounted on the slide. Her results are presented in
Table 1.Table 1 Number of Cells in Different Stages of DivisionNumber of cells
Phase Area 1 Area 2 Area 3 Total
interphase 99 79 88
prophase 12 14 16
metaphase 6 4 5
anaphase 0 2 2 4
telophase 2 3 4 93.According to the data in Table 1, the duration of the
phases of the cell cycle, from the longest to the shortest, is
A. prophase, metaphase, anaphase, telophase, interphase
B. interphase, prophase, metaphase, telophase, anaphase
C. interphase, prophase, metaphase, anaphase, telophase
D. not possible to list, since the number of cells and not
the duration was observed4.Calculate the percentage of cells in prophase. (Record your
answer as a value rounded to one decimal place.)5.If the total time for the completion of one cell cycle is 660
min, determine the time required to complete metaphase.
(Record all four digits of your answer.)- Calculate the percentage of cells undergoing mitosis.
(Record your answer as a value rounded to one decimal
place.)
7.A researcher studied the growth rate of a malignant cell in
mice. Every two days, he counted the number of cells in a
1mm^2 area, over a period of two months. Select the graph
in Figure 2, on the next page, that represents the data
collected.
