Answer:
The correct option is: begins the hydrolysis of proteins in the stomach
Explanation:
Pepsin is a protease enzyme that is <u>synthesized by the stomach</u>. It is the main gastric enzyme that helps in the <u>digestion of proteins molecules </u>present in the food.
The pepsin enzyme catalyzes the<u> acid hydrolysis of the peptide bond in the proteins</u> at a very<u> low acidic pH of 1.5-2.0.</u>
This enzyme becomes <u>inactive at pH 6.0</u> and gets <u>fully denatured or irreversibly inactivated as the pH increases to 8.0</u>.

Answer: The property that will best provide evidence that the samples are solid includes:
--> if the substance has a definite shape,
-->if the substance has a definite volume
--> if it's tightly packed.
Explanation:
According to the kinetic theory of matter, every substance consist of very large number of very small particles called molecules. These molecules, which are made up of atoms that are the smallest particles of a substance that can exist in a free state.
Matter can exist in the following states:
--> Solid state
--> liquid state or
--> Gaseous state.
The general property of a substance that is in gaseous state includes:
--> Definite shape: A substance can be grouped as a solid if it's shape is fixed that is, it doesn't depend on the shape of other materials.
--> Definite volume: A substance can be grouped as a solid if it occupies its own shape. This is due to the force of cohesion among its molecules.
--> Tightly packed: A substance can be grouped as solid if the molecular movements of the particles are negligible.
From the samples under observation by Juan and kym, if the sample that possesses the above described qualities, it is a solid rather than liquid or gas.
