Answer:
Large intestine
Explanation:
After the completion of digestion process in the small intestine, the indigestible residual materials are passed to the large intestine.
The large intestine serves three primary functions -
- Absorption of water and electrolytes
- Production and absorption of vitamins
- Formation and propelling of feces accomplishing their removal through the rectum.
When water gets absorbed, the indigestible materials get dehydrated and during feces formation they are compacted and then eliminated through the rectum.

Answer:
Taking more samples from different parts of an acre.
Explanation:
Validity and accuracy of the data is crucial for any serious research. In this particular case, the most accurate data would be obtained if earthworms would be counted on the whole acre. Of course, this would consume lot of time, people, money etc. That's why methods for estimation are used. Estimation best works with large number of samples. Since one acre equals over 4000 square meters, taking only five samples from such a big area is simply not enough for obtaining valid data.
One of the possible ways to improve estimation is to take more samples per acre while avoiding taking adjacent samples because it could be possible that number of earthworms in one part of an acre is increased (or decreased) for any reason, which would lead us to wrong conclusion.
A rock, a car, something nonliving.
