Question

Tommy is investigating a strain of bacteria. He observes that the bacteria is only found in environments with a pH range from 6 to 8. His lab partner prepares a growth medium for this bacteria with a pH of 5. Which explanation best predicts what will happen to the bacteria grown in this growth medium?

A
The bacteria will quickly die because the growth medium is too acidic for survival.

B
The bacteria will grow quickly and then begin to die because they will run out of food.

C
The bacteria will grow slowly because the growth medium will provide fewer resources.

D
The bacteria will grow quickly because they can change the pH level of the growth medium.

Answer 1

A but correct me if I’m wrong

Answer 2

Answer: A

The bacteria will quickly die because the growth medium is too acidic for survival.

Explanation: it was only found in 6 to 8 pH range so it will not survive in pH of 5
