Answer:
B. Fewer pesticides are needed because of parasitoids.
Explanation:
Herbicides are chemicals utilized to manage or command unwanted vegetation. Herbicide employment happens most commonly in row-crop cultivation, where they are employed before or throughout seeding to maximize yield productivity by decreasing other vegetation. Yields have improved considerably, and, in association with tillage, herbicide use decreases erosion, fuel usage, greenhouse gas discharges, and nutrient run-off, and preserves water.
Answer:
<h2>40</h2>
Explanation:
Calculations:
Let q²= homozygous recessive
p²= homozygous dominant
2 pq heterozygous
q² for this population is 640/1000 = 0.64
q = √o.64 = 0.8
so, P= 1- q
= 1- 0.8 = 0.2
The homozygous dominant frequency = p² = (0.2)(0.2) = 0.04
Therefore, you can expect 4% of 1000, or 40 individuals, to be homozygous dominant.
