5. How do enzymes found in your saliva aid in digestion?
AfilCa [17]

Answer:

the answer is C) They increase the rate of the chemical reactions involved in digestion

Explanation:

The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

How are currents in the Pacific Ocean affected by El Niño?
mylen [45]

The answer is; Warm water moves to the east instead of to the west


Normally, when the waters in the Pacific warm up, the prevailing winds that blow from east to west drag the warm surface currents westwards and upwelling of cold currents occur at the west coast of South America. However, in El Nino, the Pacific ocean waters heat more than usual. The prevailing winds weaken and begin to blow predominantly towards the east. The warm currents are therefore dragged to the east and cause torrential rains in Western coast South Americas.
