Simply put, skeletons are similar because the organisms processing them arose from common ancestry. All mammals for instance, have skeletons that are quite similar because all mammal skeletons arose from common ancestry in the Mesozoic age. These mammal skeletons are used in different manner by the entry of populations of organisms into different environments where individuals were selected along lines of adaptation to those different environments. Then the different populations of mammals arose with the very similar skeletons being used in very different ways. Consider yourself, your dog, and whales to see the similarities in skeletal structure with vast differences in use.
Yes. The basic structure of DNA is universal for all organisms.

To my knowledge, there are no mammals that do not have skeletons. One of the classifications of a mammal is that is has a vertebrae, which would need the rest of the skeletal structure to support it.
Anatomy is the study of the structure of organisms, and physiology is the study of their function.
The Yellow Calcareous sponge is Arthuria canariensis (formerly Clathrina canariensis, and also previously classified in the genera Nardoa, Leucosolenia, and Ascuris).Clathrina clathrus (the typical Clathrina species) is also yellow, bit has a dissimilar structure.

Amoeba, protozoans have the simplest cell structure as thery are predominantly unicellular organisms

A structure of bones connected by ligaments, as in almost all other animals with internal skeletons.
