The constant, dynamic process of continual addition of new bone tissue (bone ) and removal of old bone tissue (bone ) is a process called bone . this ongoing process occurs at both the (outer) and (inner) surfaces of a bone. it is estimated that about of the adult human skeleton is replaced yearly. this process does not occur at the same rate everywhere in the skeleton. for example, the in our skeleton is replaced at a slower rate than the .

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
