The process of maintaining stable conditions inside a cell for an entire organism) is Homeostasis requires
adjustments, because conditions are always changing both inside and
the cell. The membrane is
allowing substances in and out of the cell. The two processes that move molecules are passive and
transport
Passive transport moves molecules
