Final answer:
If the pedicle is attached in the middle, the brachiopods will be positioned in a perpendicular or upright direction.
Step-by-step explanation:
The direction of brachiopods depends on the attachment of the pedicle. If the pedicle is attached in the middle, the brachiopods will be positioned in a perpendicular or upright direction. In this case, the brachial valve will be oriented towards the top and the pedicle valve towards the bottom.
