If a person forgets to take the reading of his cell culture data now he needs to conclude among the two plates A( with 16 cells) and B (with 128 cells). Which plate has growth of more than 9hrs and which plate has growth of less than 9 hrs if they were yeast cells?
1. A with more than 9hrs
2. B with more than 9 hrs
3. A does not show yeast cell culture
4. B with less than 9 hrs
A person forgets to take the reading of his cell culture data. Now, he needs to compare among the two plates A (with 16 cells) and B (with 128 cells). By counting the number of cells in plate A, he deduces the number of divisions yeast cells must have undergone in plate A would be
1. 4
2. 8
3. 12
4. 15
