dimaraw [331]

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.

aniked [119]

When glucose is converted to ethanol by yeast, one mole of glucose is converted  into two moles of ethanol and two moles of carbon dioxide,  

and this process produce two moles of ATP.  

C6H12O6 → 2 C2H5OH + 2 CO2

When glucose is converted to ethanol by yeast (as in the production of beer) 92% of the chemical energy that was originally stored in glucose still remains in the end product, ethanol, that is produced.
