Humans can’t digest cellulose, a component of plants, very well. Imagine you developed a mutation in one of your stomach cells and it allowed your cell to start producing cellulase, an enzyme that breaks down cellulose. Every time that cell divides, the mutation is spread to another cell in your stomach and that cell can produce cellulase too. Soon, you can start getting more energy from salads than other people, because you can break down the cellulose. Which of the following terms describe this type of mutation? Select all correct answers.
