What is the organelle inside the cell that breaks down toxic chemicals?

Peroxisome
Nondisjunction
Morula
RNA

The correct answer is: Peroxisome

Peroxisomes are the organelles inside the cell that are responsible for breaking down toxic chemicals. They contain enzymes that help in the detoxification process by converting toxic substances such as hydrogen peroxide into water and oxygen. Option B, nondisjunction, is a term related to genetics and refers to the failure of homologous chromosomes or sister chromatids to separate properly during cell division. Option C, morula, is a stage in embryonic development where a solid ball of cells is formed before the blastocyst stage. Option D, RNA, is not the organelle responsible for breaking down toxic chemicals in the cell; RNA is involved in protein synthesis.
