Answer 1

Answer:

hi

Explanation:

a ) The excretory organs of flatworms (Platyhelminthes) are flame cells and function like a kidney, removing waste materials. Nephridia remove metabolic wastes from an animal's body. They are present in annelids.

b)In many marine nematodes, one or two unicellular 'renette glands' excrete salt through a pore on the underside of the animal, close to the pharynx. In most other nematodes, these specialized cells have been replaced by an organ consisting of two parallel ducts connected by a single transverse duct.

Answer 2

Answer:

A) The excretory organs of flatworms are flame cells and function like a kidney, removing waste materials.

B) Though not assigned to any major organs, the nematode turns its waste into ammonia and partly urea, but mostly the former. This is released through diffusion of the skin.

C) In annelids, the excretory organs are nephridia.

D) Major organs are the kidneys, the ureter and the cloaca. Two kidneys, each with a ureter that carries the urine produced by the kidneys to the cloaca where it leaves the body . No urinary bladder in bird.
