Suppose a population is carrying a condition controlled by two alleles: P (dominant) and p (recessive). Only homozygous individu
Virty [35]

<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>

Which three statements provide reasons that scientists are considering renewable sources of energy?
Scorpion4ik [409]

These are the three explanations that give reasons that scientists are considering renewable source of energy:

1. Renewable sources are assets implies they are old and reliable sources.

2. Most renewable sources are effectively accessible in nature.

3. Renewable resources are cost-effective in contrast with non-renewable resources.

A renewable energy source implies energy that is feasible, that can't run out, or is unending, similar to the sun. It is additionally named 'alternative energy'. These assets are fit for recovery. The recovery of these sources includes a few biological cycles on a time scale. Sun, water, air, and heat from the earth are sustainable sources that we can use to make solar-based, tidal, wind, and geothermal energy. Renewable energy is additionally called green or eco energy.

A(n) resistance is an unusually high occurrence of a disease in a certain place during a certain time period.
prohojiy [21]

The correct answer is False. The correct word is Epidemic and not resistance. 
An abrupt decrease in a host immunity of a pathogen or newly emerging novel pathogen that is found in the endemic equilibrium with the exceeded transmission threshold is where an epidemic occurs.
