- Amber fossil- An organism covered in tree resin or tree sap , which then hardens with the body of the organisms preserved inside.
- Ice fossil- An organism dies in a cold place on earth , its body becomes frozen and covered in layers of ice . The hard and soft part of the body may be preserved.
Answer: Option A. 0.820g/mL
Explanation:

Volume = 15mL
Density = Mass /volume
Density = 12.3/15 = 0.82g/mL

Sedimentary rocks are turned into metamorphic rocks by heat and pressure
I think only the second option is wrong.
