<em>The part that will not be necessary in wind pollinated angiosperm is the petals .</em>
The petal is a part of flower that is usually colorful and primarily function by attaracting insect pollinators to the flower.
<u>Since wind pollinated angiosperms do not need to attract insect for pollination, they do not need the colorful petals. They rely on wind to carry their pollen from their anthers to their stigmas (pollination).</u>
Hence, the correct option is C.
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.
