How does petrified wood form?
Petrified wood forms when wood becomes buried underground by sediment and minerals, such as silica, seep into the wood's cells. Over time, the organic material is replaced by minerals, preserving the wood's structure and turning it into stone.
The presence of white blood cell casts in the urine is indicative of pyelonephritis and red blood cell casts indicative of glomerulonephritis?
White blood cell casts in the urine are typically associated with acute interstitial nephritis, while red blood cell casts are more commonly seen in acute glomerulonephritis. Pyelonephritis is usually characterized by the presence of white blood cells in the urine without casts.

Do hairline fractures require casts?
Hairline fractures, being small cracks in the bone, typically do not require casts. These fractures usually heal on their own with rest and limited weight-bearing activity. However, depending on the severity and location of the fracture, a splint or brace may be recommended to support and protect the affected area during the healing process.

How is petrified wood different from molds and casts?
Petrified wood is when the tree is in contact with elements and minerals that solidify it into a rock or petrified tree. A mold is the fossilized imprint from an animal or plant organism, whilst a cast is when the organism died or ended up in a rock/mineral and ended up being filled with the minerals of the surroundings over time (from the limestone as example). This creates a replica of the organism once the actual organism dissolves. This is what I gathered from science class today... So I suggest you do more research if needed. Forgive me if I'm wrong. Good luck with whatever you need this for
