Answer :
Answer:
Bilaterally symmetrical.
In the analogy:
- Starfish are radially symmetrical creatures, meaning they exhibit symmetry around a central axis, like spokes on a wheel.
- Mackerel, on the other hand, are bilaterally symmetrical, which means they have symmetry along a single plane, dividing them into two mirror-image halves.
So, the completion of the analogy would be: **Mackerel : Bilaterally symmetrical**.
Answer:
Fish have different types of body symmetry. Starfish exhibit radial symmetry, which means they are symmetrical around a central point, like spokes on a wheel.
In the case of mackerel, they have bilateral symmetry. Bilateral symmetry means that the body can be divided into two equal halves along a single plane. So, the analogy would be:
Starfish : Radially symmetrical :: Mackerel : Bilaterally symmetrical
