When a plastic block is released under water, it never stays under water but instead comes to the suface of water. Explaing Why?

Assertion: Water-logged soil is physiologically dry Reason : Water dislodges air from the soil so that roots cannot breathe

7. Breathing And Exchange Of Gases_Mechanism Of Breathing

There are five animals P, Q, R, S and T. The animal P always lives in water and has gills for breathing. The animal Q can saty in water as well as on land and can breathe both, through moist skin and lungs. The animal R lives in soil and breathes only through its skin. The animal S lives on land and breathes through spiracles and tracheae. And animal T lives in water and breathes through its cell membrane. (a) Which of the animals could be Amoeba ? (b) Which of the animals could be frog ? (c) Which animal could be fish ? (d) Which animal could be grasshopper? (e) Which animal could be earthworm ?

Dust stroms and polluted rivers have made it HAZARDOUS to breathe the air and drink the water.

Assertion plants show wilting under water logging conditions Reason Root fail to respire because they do not get oxygen under water logging conditins
