The foregut includes the pharynx, esophagus, crop, and gizzard.
The midgut is primarily responsible for the absorption of nitrogenous waste.
Gaseous exchange in cockroaches occurs in the gizzard.
Malpighian tubules convert waste into glucose for excretion.
Correct Answer
Detailed Explanation
The foregut of the cockroach indeed includes the pharynx, esophagus, crop, and gizzard, as described in the NCERT context. The midgut does not deal with nitrogenous waste, gaseous exchange does not occur in the gizzard, and Malpighian tubules are responsible for converting waste into uric acid, not glucose.
