Question

what type of bacterial activity is represented in the diagram?
a generation time
b isotonic conditions
c hypertonic conditions
d hypotonic conditions

Explanation:

• Isotonic conditions mean the concentration of solutes is the same inside and outside the cell. In such a case, there is no net movement of water.
• Generation time refers to the time it takes for a population of bacteria to double in number, which is not depicted here.
• Hypertonic conditions would have more solutes outside, causing water to move out of the cell.
• Hypotonic conditions would have more solutes inside, causing water to move into the cell.
• The diagram shows no net movement of water (arrows in both directions are balanced), which is characteristic of isotonic conditions.

Answer:

B. isotonic conditions
