Which of the following functions of the digestive tract and accessory organs involves the progressive dehydration of indigestible

C. Compaction

Explanation:

Chyme enters from the small intestine into the large intestine. In the large intestine, chyme becomes solid or semisolid as the water is absorbed from it. Absorption of excess water from chyme to convert it into the feces in the large intestine is called compaction. Feces consist of water, inorganic salts, unabsorbed digested materials, and indigestible parts of food.  During compaction, enough water is absorbed and this makes large intestine one of the important organs in maintaining the body’s water balance.

The answer your looking for is a food chain grid. it describes how nature can support itself and survival of the fittest comes into play..

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
