<span>In Mary's case, the abducens is affected/ The abducens is a motor neuron that is responsible for innervating the lateral rectus muscle, this helps the pull the eye in a lateral direction. In Mary's case, only the right branch of this is affected so when she looks right the eye is simply not able to rotate laterally and she has double vision. The medial rectus muscle that is found in the right eye is responsible for pulling the eye so that she can look left. The oculomotor nerve is in charge of innervating this particular muscle and when it comes to mary's case, her cranial nerve III is not affected.</span>
Well the boiling point of an element is usually higher than that of it's melting point counterpart for one. The similarity begins when you go from right to left on the period of elements. There's an decrease and then an increase. So reactivity effects the physical traits of the element, being your similarity between the boiling and melting points :D
Only small, uncharged molecules (like 02 for example) can go in or out of the cell by simple diffusion.
Since glucose is a relatively large molecule and ions (like Na+, Cl-) have an electric charge, they are unable to diffuse into or out of the cell.
However, since ions, glucose and other big or charged molecules are necessary for the functioning of the cell, there are special means of transport for them.
Integrated into the cell wall there are membrane proteins which serve as canals for transporting specific molecules like ions, glucose, etc.
