Fish exhibits locomotion by the process of swimming. Muscles and bones bring about locomotion in fish. The body of the fish is supported by endoskeleton made up of bones. So that they have less resistance when swimming in water

Dear student 
Streamlining doesn't reduce friction, it reduces drag. In air, this is often called air resistance, Streamlining reduces air resistance because it reduces the surface area of the moving object that is put under a large force by the air.
Hope this will help 
Good Luck

(i) 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

the answer is reduces friction.the friction exerted on objects by water is known  as drag ,shape is a major factor that drag depends on. most of the things are given a streamlined shape[broad in middle and narrow at the ends] so that the object can paas easily  through water.fish has a naturally streamlined shape whereas other organisms like octopus make thewir body streamlined and can swim easily

(i) Fishes can’t live without water because fishes have gills which help them to breath in water 
(ii) Fishes have boat shape body which help them to swim in water 
(iii) Fishes gills are unable to to absorb atmospheric air due to which is fish die when we removed it
