Gastric juice  is a thin strongly acidic (pH 1 - 3 ) almost colorless liquid secreted by the glands in the stomach lining. It is made acidic by one of its constituents namely hydrochloric acid. It is because of its acidic nature that gastric juice can be  so corrosive to the lining of the duodenum.

The integrity of the inner lining of the (mucosa) of the duodenum depends on a careful balance of the "aggressive" factors (such as acid) and "defensive" factors (such as mucus) which helps to protect the delicate surface lining.

Disruption of this balance caused by too much acid (or weakened defense ) can result in erosions or ulcers .

HELP ME ASAP PLEASE.<br><br>How does water move from leaves to root? explain ​
iogann1982 [59]

During transpiration, water will evaporate from tiny holes in the surfaces of leaves into the air (the tiny holes are called stomata). As the water molecules evaporate from plant leaves, they attract the water molecules still in the plant, helping to pull water up through the stems from the roots.

Hope this helps!    *please mark me as brainliest :)
