Match the modes of transport to the molecules. tiles carrier proteins osmosis active transport simple diffusion proteins from the golgi apparatus pairs oxygen arrowboth water molecule arrowboth charged amino acid arrowboth calcium moves from low concentration to high concentration arrowboth exocytosis arrowboth

The answers are:
carrier proteins → charged amino acid     
Carrier proteins are transmembrane proteins for the facilitated diffusion of charged amino acids across plasma membranes.

osmosis → water molecule
A type of passive transport, osmosis is the diffusion of water molecules in and out of cells.

active transport → calcium moves from low concentration to high concentration
This is the movement of substances across membranes against concentration gradient.

simple diffusion → oxygen
Oxygen molecules enter through membrane by simple diffusion from an area of high to low concentration.

exocytosis → proteins from the Golgi apparatus 
This process of exocytosis is used by cells to release particles that has been packaged by the golgi bodies.

Covalent bond is the correct answer
