Rate of reaction will increase with the presence of a catalyst.
This is due to catalysts providing an alternative reaction pathway with lowered activation energy required, allowing an increased rate of reaction.
I think at Approximately 7 years the child should be able to use each hand independently. Hand control is the ability by a child to accurately use and manipulate objects, utensils, tools and even finger in isolation for functional tsak performance.
At some convergent boundaries, an oceanic plate collides with a continental plate. Oceanic crust tends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone.

The presence of Glossopteris in Antarctia proves that the continent was located closer to the equator and have since drifted to the south pole. This observation supports the theory of continental drift. </span>
