Explanation:

Streak plating relies on serial dilution across the plate to get isolated colonies. Sterilizing the loop between streaks removes most bacteria from the loop, so each subsequent streak transfers fewer bacteria, creating a dilution gradient that leads to isolated colonies.

Answer:

True
