Answer:
The grooves in the rubber are designed to allow water to be expelled from beneath the tire and prevent hydroplaning. The proportion of rubber to air space on the road surface directly affects its traction. Design of tire tread has an effect upon noise generated especially of freeway speeds
The streamlined body shape (boat shape) allows the fish to move easily in water. (ii) Fishes cannot survive outside water because fishes have gills which help them to use the oxygen dissolved in water. Gills are unable to absorb atmospheric oxygen, due to which the fish will die when removed out of water
