The question is incomplete as the frequency of alleles is not given, however, the frequency and population are given below :
Frequency of a = 0.506
total population = 500, Number of aa = 128
Answer:
The correct answer is - option C. 0.336.
Explanation:
Let, A = Normal allele, a = Defective allele
So, AA & Aa will develop normal phenotype & aa will develop defective phenotype.
Frequency of a = 0.506
So, Frequency of A = 1 - 0.506 = 0.494
So, frequency of AA = (0.494)2 = 0.244036
So, frequency of Aa = 2 x 0.494 x 0.506 = 0.499928
so, frequency of aa = (0.506)2 = 0.256036
total population = 500, Number of aa = 128
So, Number of AA = (0.494)2 x 500
= 122.018 which is almost 122 so considering it 122
So, Number of Aa = (2 x 0.494 x 0.506) x 500
= 249.964 which is almost 250 so considering it 250
It is given that, Relative fitness of AA (W11) & Aa (W12) is 1, and the relative fitness of aa (W22) is 0.
Now, mean fitness = (Frequency of AA x Fitness of AA) + (Frequency of Aa x Fitness of Aa) + (Frequency of aa x Fitness of aa)
= (0.244036 x 1) + (0.499928 x 1) + (0.256036 x 0) = 0.244036 + 0.499928 = 0.743964
So, after selection frequency of Aa
= (Frequency of Aa x Fitness of Aa) / mean fitness
= 0.499928 / 0.743964 = 0.67198 (Up to 5 decimal)
So, after the selection frequency of aa
= (Frequency of aa x Fitness of aa) / mean fitness
= 0 / 0.743964 = 0
So, frequency of a
= 1/2 of frequency of Aa + Frequency of aa
= 1/2 x 0.67198 + 0
= 0.33599 + 0
= 0.33599 which is almost 0.336

(Worth 100 Brainly points please help ASAP) (This is for science) Using page 3 of Module section 5.03 Reflecting on Core Concepts tab come up with a scientific argument:
Claim: a conclusion about a problem
Evidence: scientific data that is appropriate and sufficient to support the claim
Reasoning: a justification that shows why the data or information counts as evidence to support the claim
Make sure to cite if you quote and give resources for your argument.
Claim: Regular physical exercise has a positive impact on mental health, reducing the symptoms of depression and anxiety.
Evidence: Multiple systematic reviews and meta-analyses have found that engaging in regular physical exercise can lead to significant reductions in the symptoms of depression and anxiety. For example, a meta-analysis by Cooney et al. (2013) found that exercise had a moderate effect on reducing depressive symptoms when compared to control groups. Another meta-analysis by Rebar et al. (2015) demonstrated that physical activity was associated with decreased anxiety symptoms.
Reasoning: Exercise can lead to the release of endorphins and other chemicals in the brain, such as serotonin and dopamine, which are known to have mood-enhancing effects. In addition, regular physical activity can also improve sleep quality and reduce stress levels, both of which can contribute to better mental health.

A scientific argument consists of a claim, evidence, and reasoning. The claim is a conclusion or statement about a problem. The evidence is scientific data that supports the claim, and the reasoning provides a justification for why the data is considered evidence.
For example, let's consider the claim that "Increasing levels of greenhouse gases are causing global warming." The evidence to support this claim can come from various scientific sources such as climate data, temperature records, and ice core samples. These sources provide information on the increasing levels of greenhouse gases and the rise in global temperatures over time.
The reasoning behind this claim can be explained by the scientific understanding of greenhouse gases and their effect on the Earth's climate system. Greenhouse gases, such as carbon dioxide and methane, trap heat in the atmosphere, leading to a greenhouse effect. As the levels of these gases increase due to human activities, more heat is trapped, resulting in global warming.
To further support this argument, you can cite scientific studies and reports such as those from the Intergovernmental Panel on Climate Change (IPCC) or the National Aeronautics and Space Administration (NASA). These sources provide extensive research and data on climate change, greenhouse gas emissions, and their impacts on the environment.
Remember, scientific arguments rely on credible evidence and logical reasoning. It's important to critically evaluate the sources and data used to support your argument to ensure their validity and reliability.

Part E: Estimate Greenhouse Gas Emission
You’ll design your eco-friendly home to reduce the use of carbon dioxide compared to the average home in the state. Estimate greenhouse gas emissions for your house. Use these three government tools to generate the data you need.
First, go to the US Energy Information Administration and click “Average monthly residential electricity consumption, prices, and bills by state.” Find your state and the average kilowatt-hours of electricity used per month in your state. Multiply that number by 12 to get the amount of energy used in one year.
Then visit the EPA's Greenhouse Gas Equivalencies Calculator and enter the kilowatt-hours of energy for one year into the “If You Have Energy Data” box. Select kilowatt-hours of electricity and click Calculate. The kilowatts converted into emissions equivalents (such as miles driven and average household energy). This information will give you a better perspective on the greenhouse gas emissions for the average home in your state.
Finally, click the EPA's Power Profiler and enter the ZIP code. Choose one of the electrical companies listed (any one will work) and press Enter. Scroll down to see how much of the energy in this ZIP code comes from renewable energy and nuclear energy (a nonrenewable, cleaner energy source) compared to fossil fuel sources (oil, coal, and gas). You’ll also see bar graphs that compare your ZIP code’s energy profile to the national average.
Based on the data you gathered, answer the following questions:
What conclusion can you draw about the emissions of greenhouse gases for the average home in your state or ZIP code? What factors do you think contribute to this emission rate?
How do the emissions in your ZIP code compare to greenhouse gas emissions across the nation? Even if it’s better than the national average, is there room for improvement?

The sentence that best describes the temperatures of a city located along a windward coast is C.Cooler summer temperatures than an inland location at the same latitude.
What is affected by a body of water's temperature?A city on a windward coast experiences cooler summer temperatures than an area inland at the same latitude.
In comparison to an inland site at the same latitude, a city positioned along a windward coast will experience (b) lower summer temperatures. This area's predominant breeze originates from the lake, which will always have a moderating effect (both warmer in the winter and cooler in the summer). Climate, salt intake, hormone levels, carbohydrate intake, degree of physical activity, and some substances like alcohol and caffeine can all have an affect on total body water content.
Temperature is crucial because it affects the chemistry of water. At greater temperatures, chemical reactions typically proceed more quickly. Higher temperature water, especially groundwater, can dissolve more minerals from the underlying rock and will consequently have a higher mineral content.
Therefore, option C is correct.

Is it possible for you to find out whether a plant has taproot or fibrous roots by looking at
the impression of its leaf on a sheet of paper? Think and explain the answer.
Answer:
No, it is not possible to determine whether a plant has taproot or fibrous roots by looking at the impression of its leaf on a sheet of paper. This is because the root system of a plant is hidden underground and cannot be seen from the surface. The shape and size of a leaf can provide clues about the type of root system a plant has, but the impression of a leaf on a sheet of paper does not provide enough information to definitively identify the type of root system.

If a DNA sequence is A-T-G-A-C, write the sequence of base pairs that would pair with it.
Answer:
T-A-C-T-G
Explanation:
Deoxyribonucleic acid, widely known as DNA, is the genetic material in living cells. It is a double-stranded molecule, with each strand arising from the pair of nucleotide monomers that forms its structure. In the DNA, four nucleotides exist namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
These four bases occur in different combinations to form a sequence that makes up each strand of the DNA. However, each nucleotide pairs with one another using the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will always hydrogen bond with Thymine, while Guanine will always hydrogen bond with Cytosine i.e. A-T, G-C.
Based on the above, a DNA strand with sequence: A-T-G-A-C will pair with another DNA strand with sequence: T-A-C-T-G.
Deoxyribonucleic acid is an essential molecule that comprises nucleotides purines and pyrimidines.
The six-membered nitrogen-containing ring joined with the imidazole ring is called purines whereas, the pyrimidines are the six-membered nitrogen ring.Purines ascertained in the DNA and RNA are adenine and guanine.Pyrimidines found in the DNA are cytosine and thymine whereas, in the RNA cytosine and uracil is found.The sequence of the base pair formed from the DNA sequence
A-T-G-A-C will be:
T-A-C-T-G
The adenine always base pairs with thymine.The purine guanine always pairs with the pyrimidine cytosine in the case of DNA sequences.
Therefore, the sequence formed will be T-A-C-T-G .

Calculate the population density of 900 sheep in a plot of land that is 3.00 km by 2.00km
The population density of the 900 sheep in the given plot of land is 150 sheep per square kilometer.
The population density of 900 sheep in a plot of land that is 3.00 km by 2.00 km can be calculated by dividing the total number of sheep by the area of the land.
First, we need to calculate the area of the land. The area can be found by multiplying the length and width of the plot of land:
Area = length × width = 3.00 km × 2.00 km = 6.00 km²
Next, we divide the total number of sheep by the area to calculate the population density:
Population Density = Total number of sheep / Area = 900 sheep / 6.00 km²
Performing the calculation, we find:
Population Density = 150 sheep/km²
Therefore, the population density of the 900 sheep in the given plot of land is 150 sheep per square kilometer.
Population density is a measure of the number of individuals (in this case, sheep) per unit area. By dividing the total number of sheep by the area of the land, we obtain the population density in terms of sheep per square kilometer. In this case, the population density is 150 sheep/km², indicating that there are, on average, 150 sheep within each square kilometer of the land.

in terms of environmental impact, what's the difference between natural gas, coal, and biomass? consider both carbon dioxide (CO2) emissions and acid rain
Answer:
Natural gas, coal, and biomass differ significantly in terms of their environmental impact, particularly in relation to carbon dioxide (CO2) emissions and acid rain.
Carbon dioxide (CO2) emissions:
Natural gas produces the lowest amount of CO2 emissions per unit of energy compared to coal and biomass. This is because natural gas has the lowest carbon content and burns more cleanly than coal or biomass. Coal is the most carbon-intensive fossil fuel and produces the highest amount of CO2 emissions per unit of energy, contributing significantly to climate change. Biomass is considered carbon-neutral because it is a renewable resource, but it still releases CO2 when burned, and the harvesting and transport of biomass can have negative environmental impacts.
Acid rain:
Coal is the primary contributor to acid rain due to the high sulfur content in coal. When burned, coal releases sulfur dioxide (SO2), which reacts with water vapor in the atmosphere to form sulfuric acid. Sulfuric acid falls back to the earth as acid rain, which can have detrimental effects on soil, plants, and aquatic ecosystems. Natural gas has a lower sulfur content than coal and therefore produces less sulfur dioxide emissions, which contributes less to acid rain. Biomass also produces less sulfur dioxide emissions than coal, but the harvesting and transport of biomass can contribute to acid rain if not managed sustainably.
In summary, natural gas is generally considered to be the least environmentally damaging of the three fuels, producing lower CO2 emissions and contributing less to acid rain. Coal is the most damaging of the three, producing the highest CO2 emissions and contributing significantly to acid rain. Biomass is considered renewable and carbon-neutral, but it still produces CO2 emissions and can contribute to acid rain if not managed sustainably.
