Why do bacteria numbers start to decline when treated with antibiotic C but then
begin to increase as time goes on?
15
A) Some bacteria with resistance to antibiotic C were selected for over time.
B) Additional bacteria were added to the experimental group.
18
C) Antibiotic C degraded and thus was no longer effective.
D) This is the normal course of bacterial growth no matter which antibiotic is
applied.

The correct answer is - option A) Some bacteria with resistance to antibiotic C were selected for overtime.

Explanation:

In the given question it is stated that the bacteria number initially declines when they are treated with antibiotic C but then started to increase as time passes on. It is clear with the given data that initially the number of bacteria declines due to bacteria does not resistant to antibiotic C but after some time some bacteria developed resistance to the antibiotic and were selected and increased overtime.

The correct answer is - option A

good thing- during decomposition the organic molecules in organic matter are broken down into simpler organic molecules that require further decomposition or into mineralised nutrients

bad thing- it can be harmful in crop productivity
