The making of replicas of the original fossils, is pretty much the say way, just different materials, in which the fossils originally have been formed and preserved.
When an organism dies, be it a plant or an animal, it gets fossilized only if very quickly after the death it is covered with sediments or mud. The sediments or the mud protect the plant or animal from the outside influences, so once it is kind of in a vacuum, or protective layer if you will, in which parts of the plant or animal that are long-lasting are preserved.
The clay and plaster used for the replica, work in the same way, because they wrap around the fossil tightly and isolate it from outside influences, with the result being different though, as they just make a copy of the fossil.
Liver contains a enzyme called catalase. When hydrogen peroxide (H2O2) is added to liver, a chemical reaction occurs which results in the production of oxygen gas (O2) and liquid water (H2O).

Matter is anything that has mass. everything has matter, even the air.
Answer:
Answer: The correct answer is- Theory.
Hypothesis can be described as an assumption or proposition, which is made on the basis of certain evidences without knowing the real truth about it. It is tested further for investigation about the proposed explanation with the help of repeated experiments (using certain protocols).
When it becomes supported by repeated experimentation, it is converted into theory.
Thus, theory is the right answer.
