When a trait is said to be both polygenic and multifactorial, it means that the trait is influenced by multiple genes (polygenic) and also by multiple environmental factors (multifactorial).

Polygenic traits are those that are determined by the interaction of many different genes, while multifactorial traits are those that are determined by a complex interaction between genetic and environmental factors. Examples of such traits include height, skin color, and susceptibility to certain diseases.

In these cases, the contribution of each gene and environmental factor to the trait is typically small, and the final expression of the trait is the result of the cumulative effect of all these factors.

Explanation:

The boiling point of water decreases with an increase in elevation. At sea level, water boils at 100ºC, while at an elevation of 500 meters, it boils at 98.4ºC. This can be attributed to the change in atmospheric pressure with elevation.

The boiling point of a substance is the temperature at which its vapor pressure equals the atmospheric pressure. As elevation increases, the atmospheric pressure decreases. This is because the weight of the air column above decreases with higher altitude. At sea level, the atmospheric pressure is higher, exerting a greater force on the surface of the water, requiring a higher temperature for the vapor pressure of water to equal the atmospheric pressure. This results in water boiling at 100ºC.

At higher elevations, such as 500 meters, the atmospheric pressure is lower. With reduced atmospheric pressure, water molecules can escape more easily and the vapor pressure required for boiling is lower. Therefore, water boils at a lower temperature, specifically at 98.4ºC in this case. In summary, the impact of elevation on the boiling point of water is due to the change in atmospheric pressure. Higher elevations have lower atmospheric pressure, leading to a lower boiling point for water.

After an enzyme-catalyzed reaction has been completed, the products are released and the active site on the enzyme will return to its original shape.

Enzyme-catalyzed reactions are reactions that are catalyzed by enzymes. The rate of an enzyme-catalyzed reaction can be affected by the amount of enzyme present, the concentration of substrate, the presence of inhibitors or activators, temperature, and pH.

Enzymes are a type of protein that acts as a catalyst, which speeds up chemical reactions. Enzymes are highly specific, meaning that they will only catalyze one type of reaction. Enzymes have a specific shape called the active site, which binds to the substrate (the reactant in the reaction).

Once the reaction is complete, the products are released, and the enzyme returns to its original shape. This means that the active site is available to catalyze another reaction.

Below is the Classification of each situation as a density dependent, inverse density dependent, or density independent mortality factor.

Density dependent - Competition for food and nesting grounds among more herons lowers the likelihood that their young will survive. As the habitat of tropical bird species is lost, avian malaria mortality rates decrease.

Inverse density dependent - No matter how many antelope there are in the herd, a jaguar only kills 4 of them each week.

Density independent - Eighty percent of the lodgepole pine trees in a state park perish in a forest fire. The mortality rate of Florida manatees is extremely high as a result of an unprecedented cold period in April.

Reasons:

Nesting and food competition are two density-dependent factors that have an impact on the first species' offsprings' ability to thrive.

For the second, the environment is a density-dependent component that changes as the number of tropical bird deaths from avian malaria declines.

A jaguar kills four antelope per week, regardless of the impact on the antelope population. Inverse density dependent. This component depends inversely on density.

Independent of density, a forest fire decimates 80% of the pine trees. The amount of trees or their density in the area has absolutely no bearing on how many trees per square mile perish in a forest fire. It is therefore a factor independent of density.

Explanation:

(a) The X* coordinate of weighted center of gravity for new fire station is 1.82. (b) The Y* coordinate of weighted center of gravity for new fire station is 2.06. (c) The factors might come into play when making the final decision is Zoning Considerations, Distance from other fire stations, Available space. Option D is correct.

To determine the location for the new fire station in Green Valley, we need to calculate the weighted center of gravity based on the coordinates and the number of homes in each neighborhood.

The X* coordinate of the weighted center of gravity can be calculated using the formula;

X* = (X₁ × N₁ + X₂ × N₂ + X₃ × N₃ + X₄ × N₄) / (N₁ + N₂ + N + N₄)

where X₁, X₂, X₃, X₄ are the X coordinates of the neighborhoods, and N₁, N₂, N₃, N₄ are the number of homes in each neighborhood.

Using the given data:

X* = (0.5 × 172 + 2 × 42 + 3 × 223 + 3 × 44) / (172 + 42 + 223 + 44)

X* ≈ 1.82

Therefore, the X* coordinate of the weighted center of gravity for the new fire station is approximately 1.82.

The Y* coordinate of the weighted center of gravity can be calculated using the same formula, replacing the X coordinates with Y coordinates:

Y* = (Y₁ × N₁ + Y₂ × N₂ + Y₃ × N₃ + Y₄ × N₄) / (N₁ + N₂ + N₃ + N₄)

Using the given data:

Y* = (3.5 × 172 + 0.5 × 42 + 1.5 × 223 + 1 × 44) / (172 + 42 + 223 + 44)

Y* ≈ 2.06

Therefore, the Y* coordinate of the weighted center of gravity for the new fire station is approximately 2.06.

When making the final decision on the location of the fire station, several other factors might come into play;

Zoning Considerations: The city needs to consider any zoning regulations or restrictions that might limit the potential locations for the fire station.

Distance from other fire stations: The proximity to existing fire stations is an important factor to ensure efficient coverage and response times across the area.

Available space: The availability of suitable land or buildings that meet the requirements for a fire station, such as accessibility, size, and infrastructure, should be considered.

Ultimately, the decision should take into account a combination of factors, including zoning considerations, distance from other fire stations, and available space. This comprehensive approach ensures that the fire station is strategically located to serve the four neighborhoods effectively and efficiently.

Hence, D. is the correct option.
