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.
Answer:
With few exceptions, all cells in a person’s body have the same DNA and genes. As cells divide and grow different genes are expressed, resulting in different cell types. As cells divide and grow different genes are expressed, resulting in different cell types.

Answer:
D. Be eliminated
Explanation:
Competition in biology is the process of interaction between two or more organisms, which are using the same resources e.g food, space, mate or occupying the same ecological niche. Competition between organisms often result in one or bother organisms getting harmed due to the strive for a limited resource.
Hence, in the case of two warblers occupying the same habitat and feeding on the same prey, competition is inevitable between these two species of organism. Therefore, the competition will eventually cause one of the species to be eliminated or killed.
