Steroid hormones easily diffuse through the cell membrane. The hormone binds to its receptor in the cytosol, forming a receptor–hormone complex. The receptor–hormone complex then enters the nucleus and binds to the target gene on the DNA.

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

<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
