Match the following structures/terms of frogs with their correct descriptions: COLUMN I (Structure/Term) 1. Cloaca 2. Cranial nerves 3. Mesorchium 4. Tadpole 5. Ecological role of frogs COLUMN II (Function/Description) A. Double fold of peritoneum attaching testis to kidney B. Opens separately into cloaca in females; passage for urine, faeces, and gametes in males C. Larval stage that undergoes metamorphosis into adult D. Maintain ecological balance by eating insects and linking food chains E. Ten pairs arising from brain
