Question

The backbone is made up of 33 small bones called _______.

a. Vertebrae b. Vertebrates C. Cerebrum

​

Answer 1

Answer:

Vertebrae.

____________

Answer 2

Answer:

a. Vertebrae (singular vertebra)

Explanation:

It cannot be Cerebrum as it is the largest part of the brain (when compared to Cerebellum and Medulla). It is nowhere related to the structure of the backbone.

It cannot be Vertebrates either as Vertebrates refer to organisms which have a backbone.

Vertebrae is the plural form of Vertebra which are the small bones which make up the vertebral column (or backbone).
