Sunscreen pollution in oceans can lead to damage to corals (known as coral bleaching). To study this, the student collected 6 different corals from the Great Barrier Reef, placed each coral sample in its own tank and added sunscreen to each tank. After three weeks, they observed the health of the coral by taking a sample from each coral and observing the sample under the microscope.

1. How many replicates did the student have in this experiment?

2. Are these replicates considered technical replicates, biological replicates, or pseudo-replicates?

3. Is there anything about design of the experiment that will make it difficult for the student to draw conclusions from their data? Explain your answer.
