Some plants also have large leaves to soak up nutrients and water, very helpful in this biome since it rains a lot. - Having some needles cased in wax, withstand cold temperatures and losing water from their leaves. - Having thin bark and shallow roots enables trees to withstand fire.
Explanation: If the rate of photosynthesis increases, then the number of bubbles will increase.
If the stimulus reaches the threshold an action potential will be generated. If the stimulus doesn't reach it no action potential will be generated. If the stimulus will be stronger the action potential will have the same amplitude. The refractory period makes it harder to generate an action potential so they decrease the frequency of action potential production.
The theory developed by Wegener that the continents of the Earth were once a part of a single big super-continent is based on his observations that these continents fir together as a part of the jig-saw puzzle. And these observed continents have similar flora and fauna along with similar rock formations. Such a derivation of theory from observations is an inductive reasoning.
Hence, the answer is 'inductive reasoning'.
