Nanobubbles are tiny gas bubbles that are less than 200 nanometers in size. These bubbles have properties that can have important impacts on living organisms. Researchers have conducted studies on the impact of nanobubble water on both plants and animals.

In one study, plants were grown hydroponically with either normal water or air-based nanobubble water for 4 weeks. The changes in height, length, and weight of the plants were measured, as shown in Graph 1. In a second study, fish were grown in both normal water and air-based nanobubble water, and the change in their weight was recorded after either 3 or 6 weeks as shown in Table 1.

Table 1

Fish Type Kept for Normal Water Nanobubble Water
Sweetfish 3 weeks Initial weight (kg) 3.0 3.0
Final weight (kg) 6.4 10.2
Rainbow Trout 6 weeks Initial weight (kg) 50.0 50.0
final weight (kg) 129.5 148.0

Which of the following conclusions are supported by the data in Table 1?


The mass of the sweetfish depends on the mass of the plants.


The mass of the sweetfish in normal water had the smallest difference of all the fish measured.


The mass difference of the rainbow trout in nanobubble water is most closely related to the mass of the plants in the nanobubble water.


The mass of the rainbow trout in normal water has the smallest difference in growth of the fish measured.
