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
