Answer: she wants the water to turn green and green is neutral on the PH scale. If the water is turning acidic she might want to add a bit of baking soda to balance out the acidity with a bit of alkaline. Minerals can balance acid. If the water is too much of a base she may consider adding something a little acidic to balance it.

Explanation: the science of PH balancing

On average, activated yeast cells divide once every 120 minutes; that is, each individual cell divides into two individual cells
astra-53 [7]

Answer:

The correct answer is 4,960,000

Explanation:

If a yeast cell divides into two yeast cells in 120 minutes that means a yeast cell needs 2 hours to get double. So according to the question 2 hours ago a yeast colony consisted of 310,000 cells that means the present colony should have 620,000 cells.

So after six hours from now, this population will divide three times in six hours because the generation time of yeast cell is 2 hour and each time the number of cells will double.

Therefore, in first time the number will increase to 1,240,000(620000*2), the second time the number will increase to 2,480,000(1240000*2) and after final division, the number will be 4,960,000(2480000*2).

Therefore after 6 hours from now, the approximate number of yeast cells will be 4,960,000.
