Starting with a fertilized egg (zygote), a series of five cell divisions would produce an early embryo with how many cells?
Correct answer: D. 32
- A. 4
- B. 8
- C. 16
- D. 32
Explanation
Starting with a fertilized egg (zygote), a series of five cell divisions would result in a total of 32 cells in the early embryo.The number of cells at each division can be calculated using the formula:Total number of cells=2nwhere n is the number of cell divisions.For five cell divisions (n=5), the total number of cells would be:Total number of cells = 25 =32
