Allele that causes yellow eyes (Y) is dominant over the allele that causes orange eyes (y)

Y = 85% = 0.85 and

y = 100% - 85% = 15% = 0.15

f(y) = square root of y = √y = √0.15 = 0.387

frequency of the allele that causes orange eyes = 0.387

Once we know the value of y, Y + y = 1

Putting the value of y, we get

Y = 1 – 0.387

<span>Frequency of the dominant allele that causes yellow eyes = 0.61</span>

What are brownfields​
Daniel [21]

The lands which are lef unuse after  it is affected by environmental contamination.

<u>Explanation:</u>

  • Brownfields are abandoned or unused fields where reuse is hindered by real or observed environmental contamination. The places may include localities destroyed by hazardous materials, petroleum or mine-scarred land.
  • Brownfields are found in a city or town's manufacturing section, on areas with discontinued factories or industrial buildings, or other earlier contaminating operations like steel millhouses, refineries or landfills. It is mainly found in urban cities where there is normally a stronger potential to redevelop these localities.
  • Some of the most frequent contaminants known at Brownfield sites are from fuels such as grease, propellant, diesel and kerosene from subterrene storage tanks, floor drains, External storage of barrels and machine, and cleaning solvents.

A meadow ecosystem includes many species of grasses and small shrubs, several herbivores, and a few carnivores. A fungus coloniz
Stels [109]

A field habitat vegetated by grass and other non-woody plants (grasslands) is known as a meadow. They are of ecological benefit as they are open, sunny regions, which fascinate and support fauna and flora that could not survive in other conditions.  

In the given case, when a fungus colonizes the meadow and destructs the majority of its vegetation, which comprises species of small shrubs and grasses, then this may result in the decline of herbivore species due to lack of vegetation on which they survive, which will eventually result in the reduction of carnivore species, as they feed on herbivores.
