<span>The answer is B. 72.25 percent.
The Hardy-Weinberg principle can be used:</span>
<em>p² + 2pq + q² = 1 </em>and <em>p + q = 1</em>
where <em>p</em> and <em>q</em> are the frequencies of the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq</em> are the frequencies of the genotypes.
<span>The <em>p</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15
To calculate the <em>P</em> allele frequency (<em>p</em>), the formula <em>p + q = 1</em> can be used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85
Knowing the frequency of the <em>P</em> allele (<em>p</em>), it is easy to determine the frequency of the <em>PP </em>genotype (<em>p²</em>):
p² = 0.85² = 0.7225
Expressed in percentage, p² = 72.25%.</span>
They are both renewable resources
Vegetation controls water and nutrient loss from ecological lesson can we learn from the controlled experiment on the clearing of forests.
<h3>
What about clearing of forest?</h3>
- Deforestation is the intentional clearing of wooded land.
- Forests have been cleared throughout history and into the present era to make room for agriculture and animal grazing as well as to obtain wood for fuel, manufacture, and construction.
- Deforestation has dramatically altered the landscape all around the planet.
- The process of permanently removing vegetation, such as trees and bushes, together with their roots, is known as clearing woods and forests.
- There are both direct and indirect causes of deforestation.
- Natural factors including storms, fires, parasites, and floods are among the direct culprits.
- Human activities include the extension of agriculture, the raising of livestock, the extraction of timber, oil, and minerals, the building of dams, and the development of infrastructure.
