Kidneys are bean shaped organs present in veterbrates and it is located in the retroperitoneal space. Kidney filtration involves where blood passes through the afferent arterioles and enters the glomerulus where blood that can be filter like nitrogenous waste and water moves towards the glomerulus and nonfilterable substances such as cells and serum albumins pass out through efferent arterioles.

Explain how invertebrates can be used to monitor water pollution?
Ira Lisetskai [31]

Explanation:

Many invertebrate animals cant survive in water that has been polluted and resulted in a lowering of oxygen concentration so the presence or absence indicates the extent to which a body of water is polluted.

Lichens can be used to indicate air pollution as they grow exposed to places such us rocks and tree barks. They need to be efficient at absorbing water and nutrients to grow there. Rain water contains enough nutrients to keep them alive. Air pollutants dissolve in rain water especially sulfur dioxide can damage lichens and prevent them from growing. This makes them a natural indicator of air pollution.
