5. how do enzymes found in your saliva aid in digestion?

a. they provide energy to initiate the chemical reactions involved in digestion
b. they decrease the rate of the chemical reactions involved in digestion
c. they increase the rate of the chemical reactions involved in digestion
d. they aid in the process of moving food more quickly to the stomach
e. they are consumed as part of the chemical reactions involved with digestion

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.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

the answer is 100% density i've answered this question before and done the quiz myself.
