Where do our memories get stored and how are they retrieved again? How can learning be improved? What is the difference between
Margarita [4]

Answer:

Memories aren't just stored in one part of our brains. Different parts are stored in different brain regions, but the hippocampus is memories are formed and later accessed.  

Learning can be improved by paying attention when learning something new so that you can take in the knowledge.

Explicit memories are conscious and can be verbally explained, however, implicit memories are usually nonconscious and are not verbally articulated.

Explanation: I'm sorry but I don't know the answer to your last question, so I hope you figure out the answer to that one...........also hope this at least helps you out somewhat:)

Use the principles of diffusion to explain why oxygen molecules in the tissues of the lung go into the blood
Keith_Richards [23]

Answer:

Oxygen molecules in the tissues of the lung diffuse into the blood because the concentration of oxygen in the lung's tissues is more than the concentration of oxygen in the blood.

Explanation:

Diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. Molecules in diffusion move <em>downward the concentration</em> <em>gradient</em> created by difference in concentration between two regions until an <em>equilibrium (equal concentration in the two regions)</em> is established.

Oxygen molecules diffuse into the tissues of the lung when an organism breathes-in during the process of breathing. The molecules in the now oxygen-rich tissues eventually start diffusing into the blood in the lung because the blood passing through the lung is always de-oxygenated or has lower oxygen concentration compared to the tissues of the lung.

Oxygenated blood moves into the heart, pumps round the body by the heart, gets depleted of oxygen and eventually find its way back to the lung where the process is repeated.

Diffusion of oxygen from the tissues of the lung into the blood will keep happening as long as oxygen keeps getting dissolved into the lung's tissues and an equilibrium is yet to be established between the tissues and the blood.
