Answer:

<u>2,048 cells</u>

Step-by-step explanation:

Number of cells after 1 hour = 4 * 2 = 8

Number of cells after 2 hours = 8 * 2 = 16

Number of cells after 3 hours = 16 * 2 = 32

Number of cells after 4 hours = 32 * 2 = 64

Number of cells after 5 hours = 64 * 2 = 128

Number of cells after 6 hours = 128 * 2 = 256

Number of cells after 7 hours = 256 * 2 = 512

Number of cells after 8 hours = 512 * 2 = 1,024

Number of cells after 9 hours = 1,024 * 2 = 2,048
