State how each of the following features enhance efficient movement of fish in water:
(i) Scale
(ii) Body shape

Answer:

i)
Answer
- Scales overlap and points backwards to allow water to pass over the fish easily without resistance.
ii)
- Has streamlined body shape to reduce resistance against movement and to enable the fish cut through water easily.
