7) The cloaca is common opening of the urinary, genital, and intestinal tract in animals. It collects waste from these three compartments and excretes it outside the body. The cloaca has three main sections: the coprodeum, the urodeum, and the proctodeum. The coprodeum collects the waste from the colon while the urodeum collects urine directly from the ureters or bladder. The urodeum also connects the reproductive tract. The urodeum and coprodeum empty into the proctodeum before excretion.
Right option is cloaca.
8. A pseudocoelomate is an organism whose body cavity is not obtained from the mesoderm. These are group of organisms with a three layered body. A fluid filled cavity lies between the endoderm and the mesoderm known as the pseudocoel. It is also known as a blastocoelomate as it is derived from the blastocoel of the embryo. Body fluids bathe the organs. The organs receive nutrients and oxygen from body fluids. It lacks the endothelial lining of a coelum. The inner surface of body wall is lined by mesodermal tissue. The gut is not lines with mesodermal tissue.
Right option is e. All of the above are correct.
9. Plathymenthis can reproduce sexually or asexually, although sexual reproduction is preferred. Hermaphrodites can fertilize their own eggs. Hermaphrodites can be monecious (planarias and taenias) or dioecius (both gametes; Scictosomes). They reproduce asexually by binary fission and regeneration. Their development can be direct or indirect. In direct development, the offspring resembles adults in all aspects except size and color. Their fertilized eggs form larval stages that can live outside the host for 24 hrs. They enter the host to form sporocyst.
Right option is e. All of the above are possible in this Phylum.
