Moninder wants to find out the best temperature for mustard seeds to germinate. He uses three Petri dishes. Each dish has a layer of moist tissue paper covered with 30 mustard seeds. Moninder puts one dish in a warm cupboard, one in a cool cupboard and one in a refrigerator. He waters all of the seeds regularly for 21 days. His results for the first four days are shown in the table.
| Number of germinated mustard seeds | Number of germinated mustard seeds | Number of germinated mustard seeds | Number of germinated mustard seeds | |
| Day 1 | Day 2 | Day 3 | Day 4 | |
| Warm cupboard | 0 | 5 | 20 | 24 |
| Cool cupboard | 0 | 2 | 8 | 14 |
| Refrigerator | 0 | 0 | 0 | 0 |
What conclusion can you draw from Moninder's results?
