Answer:

Mechanical Digestion

The large pieces of food that are ingested have to be broken into smaller particles that can be acted upon by various enzymes. This is mechanical digestion, which begins in the mouth with chewing or mastication and continues with churning and mixing actions in the stomach.

Mechanical digestion is the physical act of breaking down the food by non-chemical means.

29. What conditions would cause a molecule to diffuse from the outside of the structure shown to the inside?
dmitriy555 [2]

Answer:

The conditions that would cause a molecule to diffuse from outside to inside of a structure is a higher concentration of that molecule outside and the presence of a semipermeable membrane that facilitates its passage.

Explanation:

The process by which a molecule passes from a place where it is more concentrated where its concentration is lower - crossing a semipermeable membrane - is called simple diffusion.

<u>Simple diffusion is a mechanism that does not require energy and responds to a concentration gradient</u>. When a molecule is more concentrated in a space it can enter the space where it is less concentrated .

The cell membrane is an example of a semi-permeable membrane where the simple diffusion process occurs.
