The alpha subunit dissociates from the beta and gamma subunits and interacts with other molecules, ultimately triggering a cellular response. ... GTP is hydrolyzed to GDP, and the signaling molecule comes off of the receptor.

A drought causes a wildfire which destroys a forest. Which Earth systems interact during this process? (1 point) Select one: a.
Ne4ueva [31]

<u>Answer:</u>

<em>It is the biosphere and hydrosphere that interact when a drought causes a wildfire that destroys a forest. </em>

<u>Explanation:</u>

Hydrosphere consists of all the water bodies of earth like oceans, seas, rivers, lakes etc.  a drought occurs due to scarcity of water which affects the hydrosphere. The scarcity of water causes plants and trees to dry up and become more prone to catching fire

Biosphere includes all the living organisms of the earth. It includes plants, trees, birds, insects, animals etc. A drought dries up a whole area and a small fire that starts up somewhere in  a forest would then engulf the whole forest.
