What happens to the substance in the liver that interacts with the hydrogen peroxide when these two subtances are mixed?

When the liver interacts with the hydrogen peroxide, the oxygen gas it released. The hydrogen peroxide is broken down into water, and oxygen, which leads to the formation of foam as the oxygen bubbles escape the liver. The substance that interacted with liver is an enzyme as it remains unaltered. This enzyme is known as catalase. The liver can be reused to give the same reaction again with unused hydrogen peroxide, which proves that the substance in the liver (catalase) remains unaltered.

i think it is dna, i'm not totally sure but i think it might be.

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
