The correct answer is this: IT BECOMES LESS DENSE AND RISES TO THE SURFACE.
The water at the earth's poles are cold and dense. This cold water sink and move along the ocean floor in a current. As it moves towards the equator, the cold water from the poles push up the warmer water, this becomes less dense and rise to the surface.

A concentrated buffer can neutralize more added acid or base than a dilute buffer, because it contains more acid/conjugate base. However, any buffer will lose its effectiveness if too much strong acid or base is added.
There are many methods used by manufacturers to stop or reduce oxidation of food to prevent its spoilage. These methods include:
Addition of a poisonous chemical substance such as sulfur dioxide to kill microbial growths.
Removal of oxygen to prevent aerobic oxidation of the food substances.
Keeping food dry to remove the water necessary for microorganisms to survive.
Reducing temperature so that microorganisms do not oxidize the food quickly.
The correct answer is "headache and confusion".
The human body has several mechanisms of action in order to protect critical organs from excess blood pressure and flow. When these mechanisms are not successful in protecting the capillaries of the brain, the patient could suffer from cerebral edema (swelling of the brain) and papilledema (swelling of the optic nerve). These conditions could cause severe headache, confusion, motor and sensory problems and visual disturbances.
