Question

Different animals have different arrangements (or organs) for excretion, which depend on the constitution of the animal. Give some example for this statement​

Answer 1

$\huge \bold { \fbox { \underline \pink{required \: answer}}}$

different different animals have different arrangements organs for excretion which depend on the constitution of the animal..For example:

1. In amoeba (and other single celled animals), the waste material carbon dioxide is removed by diffusion through the cell membrane, but nitrogenous wastes (like ammonia) and excess water are removed by the contractile vacuole
2. In earthworm, the tubular structures called nephridia are the excretory organs. In addition to nephridia, the moist skin of earthworm also acts as an excretory organ.
3. In human beings, the microscopic thin tubules form nephron, which functions as excretory unit. About 1 million nephrons taken together form the excretory organ of human beings called kidney.
4. In cow carbon dioxide is excrete, and urea ( in the form of urine ), as waste products. Carbon dioxide is being excreted by the lungs of the cow ( while 'exhaling' ) and urea is being excreted by the kidneys in the form of urine

Answer:

different different animals have different arrangements organs for excretion which depend on the constitution of the animal..For example:

   In amoeba (and other single celled animals), the waste material carbon dioxide is removed by diffusion through the cell membrane, but nitrogenous wastes (like ammonia) and excess water are removed by the contractile vacuole
