NEED URGENT HELP PLZ What is the evolutionary significance of developing pouches on animals such as kangaroo? (What makes a pouch a good adaptation?)

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !

it would lead to upper respiratory infections and pneumonia.
