Answer:
Bill should classify the organism as a bird.
Explanation:
It would be right for Bill to classify the newly discovered organism as a bird. This is because the birds are a category of animals which have feathers as well as hollow bones. As for the flying criteria, not all birds belonging to this category can fly. For example, ostrich and kiwi cannot fly but yet still belong to the category of birds, Hence, this newly found organism can be classified into birds as it has feathers and hollow bones.

Cadherin is the protein complex present in the cell which is responsible for the sticking together of cell in tissue-like in the skin. The cadherin junctions allow the communication between the cells and the loss of the cadherin could cause cancer.
The cadherin junction is involved in the signalling pathway in the cells like in the Rho GTPase signalling, Ras signalling and many others which shows that they are responsible for the biological processes in an organism.
Thus, Option-1 and 3 are correct.
All types of matter are made up of atoms...
