Answer: Peroxides degrade to form oxygen gas, water and foam.
Explanation:
A foam forms when bubbles of a gas are trapped in a liquid or solid. In this case oxygen is generated when hydrogen peroxide breaks down into oxygen and water on contact with catalase, an enzyme found in liver or kidney.
Answer:
Kingdom --> phylum/division --> class --> order --> family --> genus --> species
Explanation:
The formal system of classification used in taxonomy was introduced by a Swiss scientist named Carolus Linnaeus.
He first split living things into a general category called KINGDOM.
- The kingdom is further split into large smaller groups called PHYLUM (for animals) and DIVISION (for plants).
- Each phylum or division is broken down into CLASSES.
- Each class is broken down into ORDERS
- Orders into FAMILIES,
- Families into GENUS
- Genus into SPECIES
Thus, the system of classification from highest (most general category) to the lowest level is as follows: Kingdom --> phylum/division --> class --> order --> family --> genus --> species
