Autophagy is a process where cells degrade and recycle their own components. Damaged or unnecessary cellular material is enclosed in a membrane, forming an autophagosome, which then fuses with a lysosome. The lysosome contains enzymes that break down the materials for recycling.\n\nIt is a work created by CG, not created by AI. \nIt was designed and created by myself.

Unique geothermal features where hot springs deposit iron-rich minerals, creating reddish-brown formations resembling molten chocolate. These iron-oxide deposits are formed as the hot, mineral-laden water flows out and cools, precipitating the iron and other minerals. They were first documented by members of the Hayden Geological Survey of 1871, led by geologist Ferdinand V. Hayden.
