Regional carrier
Explanation:
Like in many countries, in United States, the airlines are either privately owned or publicly owned. In the United States, airlines are categorized in to major airline carriers, national airline carriers and regional airline carriers by the revenue it generates.
Accordingly, if an airline generates revenue more than 1 billion dollar in a year, it falls in the Major Airline carriers category.
It the revenue generated by the airline is within the range of $100 million to $1 billion, then it is called National airline carriers.
However, if the revenue is less than 100 million dollar for a year, then that airline is called a Regional airline carrier.

Hydrogen gas/bubbles
Explanation:
Photosynthesis is defined as the process by which green plants and other organisms like blue-green algae etc. synthesize organic matter. In the presence of light energy, they convert CO2 and H2O into organic sugar with the release of O2 gas.
The plant was performing photosynthesis since there is the presence of CO2 (baking soda) and water and therefore the bubbles seen is hydrogen gas guven off from photosynthesis .
6CO2(g) + 6H2O(l) --> C6H12O6(s) + 6O2(g)
