as a result of diffusion the concentration of many tpes of substances

diffusion taks place

the dispersal of ink in a beaker of water is an exmple of

heavy rains: flooding::

sugar molecules can enter cells through the process of

channels utilizing faciliated diffusion

whihc of the following is not characteristic of faciliated diffusion

which of the following expands energy

which of the following enters a cell by active transport

the process by which water passes into or out of a cell is called

the sodium potassium pump usually pumps

ion channels: ions::

ridding the cell of material by discharging it form sacs at the cell surface is calledd

molecules that are to large to be movied across a cell membrane can be removed from the cell by

molecules that are too large to be moved through the membrane can be transported into the cell by

endocytosis: exocytosis::

placing a plant into a hypertonic environment will

a calcium ion channel will alway

in phagocytosis and pinocytosis the plasma membrane brings in materials by forming a

active transport systems are a form of cell transport that requires energy from molecules of

++++allows a cl to stockpile substances in far greater concentrations than they ocur outside the cell

conduction of nerve impulses is possibel becasue of the

the process in whichan amoeba engulfs its prey and takes it in is known as
