Answer:
The frequency of individuals with the dominant phenotype is 0.83.
Explanation:
We are provided with:
Black allele has completed dominance over brown allele
T. no of dogs (dominant)= 2000
No. of black dogs (dominant) = 1660
From Hardy-weinberg equilibrium
Frequency of individual - (individual/ Total population)
Frequency of black dogs = 1660/2000 =
0.83
So, The frequency of individuals with the dominant phenotype is 0.83
Oxygen, neccessary for cellular respiration, is the answer. As oxygen becomes scarce, your cells begin to aerobically produce very little ATP, in effect fermenting and producing lactic acid.
More action is needed to ensure safeguards are in place to protect these areas. Nature reserves and other ways of setting land aside to protect species had been a key strategy in the conservation of biodiversity.
