Answer:
The correct option is;
D. 45%
Explanation:
From the Hardy- Weinberg law, we have;
p² + 2·p·q + q² = 1
p + q = 1
Where:
p = Dom inant allele frequency in the population
q = Recessive allele frequency in the population
p² = The percentage of individuals in the population that are hom ozygous dominant
q² = The percentage of individuals in the population that are homo zygous recessive
2×p×q = The percentage of hete rozyous individuals in the population
The number of individuals that express the recessive phenotype = 86
The number of individuals in the population = 200
The percentage of individuals that express the recessive phenotype, q² = 86/200 = 0.43
Therefore;
q = √0.43 = 0.656
p + q = 1
p = 1 - q = 1 - 0.656= 0.344
∴ The frequency of individuals that express the do minant phe notype, p = 0.344
The percentage of heterozyous individuals in the population = 2×p×q × 100 = 2 × 0.656 × 0.344 × 100 = 45.15% ≈ 45%
Answer:
Advantages: Wind turbines do not actively create green house gases, wind is an indirect solar energy (which means it never runs out), and it has a fairly high net energy
Disadvantages: NIMBY effect (not in my backyard, it means people support it, but they don't want to be near it), transportation and construction of materials cause greenhouse gases, and wind turbines can kill/harm birds and bats
Explanation:
Gathering, constructing and transporting materials to build wind turbines releases green house gases, because of vehicle's combustion and factory emissions. However, wind turbines rely on a renewable resource that a) never runs out, and b) is a clean source of energy. Compared to nonrenewable energy sources, wind is a good energy source.
I assume that the mushroom gets eaten by an animal. If that's not the answer you're looking for.. my apologies.
Answer:
unlike bacteria cells, plant and animal cells both have membrane. Bacteria cells lack membrane. Bacteria multiple by binary fission.
