Answer to Problem 15STP

The table below represent the correct match from the Column A to Column B.

Column A	Column B
eyespots	sensitive only to light and dark, and are unable to resolve images
ganglion	head ganglion(brain), usually attached to longitudinal nerve cords that are interconnected across the body by transverse branches.
auricles	auricles (ear-like flaps) that sense water currents.

Explanation of Solution

1. Eyespots- This is sensitive only to light and dark and are unable to resolve images.

2.Ganglion- Its head ganglionis attached to longitudinal nerve cords that are interconnected across the body by transverse branches.

3. Auricles- Auricles are the ear-like flaps that sense water currents.
