What can a baby do that an adult Cannot?
Babies can see things that adults can’t — but don’t have any way of telling us about them. Babies who are between three- to four-months-old are able to see differences in pictures with far more detail than older people, meaning that they can see colours and objects in a way that grown adults never will be able to.
How can you tell if a bone is human?
There are generally three levels of identification that can be utilized to distinguish between human and non-human animal bones: 1) gross skeletal anatomy, 2) bone macrostructure, and 3) bone microstructure (histology).
Which is longest bone in human body?

What’s the strongest part of the human body?

Several types of cells take part in this remodeling: Scientists divide all the bones into four groups: short bones, long bones, irregular bones, and flat bones. They are also distributed in two different systems: the axial skeleton and the appendicular skeleton.
