Explanation / Answer
1. The answer is: b. hindgut fermentation.
Vertebrates that have an enlarged cecum, colon, or both, and gut chambers that are specialized to support communities of mixed, fermenting microbes are known as Hindgut fermentation.
2. The false statement is: c.) In vertebrates, disaccharidases are found in the apical membrane of foregut epithelium.
The correct statement is: In vertebrates, disaccharidases are found in the apical membrane of midgut epithelium.
