Fat acts as subcutaneous insulation of body for thermoregulation
Fat present in the subcutaneous layer acts as an insulator to prevent the loss of heat from internal body environment during cold climates. It also helps in reserving food during the periods of food scarcity.
The subcutaneous fat or adipose tissue lies just below the skin surface or in between internal organs. Being poor conductor of heat it acts as a a good insulator. It reduces the heat loss from the body, i.e., regulates the body temperature.
Fishes respire with the help of gills. Gills are richly supplied
with blood capillaries and can readily absorb oxygen dissolved
in water. Since fishes cannot absorb gaseous oxygen they die
soon after they...
Anything that occupies space and has mass is called matter. Matter can exist in three physical states—solid, liquid, and gaseous.
Chair and almond are forms of matter in the solid state.
