Answer:
Considering A is a picture of a fibrous joint, a suture on the skull, the true answer is c. It becomes ossified late in adult development
Explanation:
Fibrous joints are connected by dense connective tissue, consisting mainly of collagen. A suture is a type of fibrous joint that is only found in the skull (cranial suture). This specific type becomes ossified late in adult development and it is called craniosynostosis, when the fusion is before birth.  These joints are synarthroses.

The mass of an atom is contained primarily in its NUCLEUS.
An atom is made up of three sub particles, which are proton, neutrons and electrons. The proton and the neutrons are located in the nucleus of the atom while the electron  are located outside the nucleus where they move about in continuous motion around the nucleus. The proton and the neutrons, which are located in the nucleus have the same relative mass of 1, which has been estimated to be about 2,000 times bigger than that of the electron, which has a relative mass of 0.0005. This shows that, the mass of an atom is located primarily in its nucleus. <span />
        
                    
             
        
        
        
Answer:
Despite a generally high security standard, <u>accidents can still happen.</u> It is technically impossible to build a plant with 100% security. A small probability of failure will always last. The consequences of an <u>accident would be absolutely devastating both for human being as for the nature.</u>
Nuclear power plants as well as nuclear waste could be<u> preferred targets for terrorist attacks. </u>No atomic energy plant in the world could withstand an attack. Such a terrorist act would have <u>catastrophic effects for the whole world.</u>
