Answer:
A flat sheet of connective tissue that extends beyond the muscle fibers to attach the muscle to bone is a TENDON.
Explanation:
Tendon can be described as a fibrous connective tissue which functions mainly to attach muscles to bones hence, playing a major role in the movement of the bone or structure. Tendons also function to connect muscles to other structures like the eye ball. 
Contrary to the tendons, ligaments are also fibrous connective tissues which are involved in the attachment of bone to bone. Hence, ligaments play major role in holding the structures and keeping them stable. 
 
        
             
        
        
        
The three substances that cause a double displacement reaction to occur are:
(i)   Ionized compounds. These are usually water.
(ii)   A gas that bubbles out a solution.
(iii)  A precipitate.
In double displacement reaction is where two new compounds are formed when two parts of two compounds switch places. For example; when sodium chloride combines with silver nitrate, the two new compounds formed are Sodium nitrate and silver chloride reason being sodium and silver switched places.
