sammy [17]
That is true.

These are the three types:

Igneous- form when magma cools down and hardens.

Metamorphic- form under earth's surface after particles undergo intense heat and pressure.

Sedimentary- forms when different layers of sediment accumulate on top of each other and harden creating a solid piece.

starch is digested by amylase in mouth, but it is not digested in the stomach. what is the reason for this?
Step2247 [10]

Answer:

Explanation:

Only about five percent of starches are broken down in the mouth. (This is a good thing as more glucose in the mouth would lead to more tooth decay.) When carbohydrates reach the stomach no further chemical breakdown occurs because the amylase enzyme does not function in the acidic conditions of the stomach.
