OLEGan [10]

Answer:

Both depends on different factors.

Explanation:

The rate of movement of the air bubble is not exactly the same as the rate of water loss from the plant because both depends on different environmental factors. The higher rate of movement of the air bubble occurs due to removal of pressure while on the other hand, the rate of water loss from the plant occurs due to temperature. So both air bubble and transpiration process depends on different environmental factors.
