Question

The __________ of most birds has a large, medial keel for attachment of flight muscles.

Answer 1

The keel is the structure in most birds that is responsible for the attachment of flight muscles.

Step-by-step explanation:

The structure responsible for the attachment of flight muscles in most birds is called the keel. The keel is a large, blade-shaped projection that projects ventrally from the sternum (breastbone). It provides a large surface area for the attachment of flight muscles, allowing birds to generate the necessary power for flight.
