In a population of pea plants, 36 plants are homozygous for the dominant trait of yellow peas (YY), 48 plants are heterozygous f
baherus [9]

Answer:

The correct answer would be C. 0.60

It can be calculated with the help of Hardy-Weinberg equation i.e

p² + q² + 2pq = 1

Also, p + q = 1

  • where p represents the frequency of dominant allele.
  • q represents the frequency of recessive allele.
  • p² represents the frequency of homozygous dominant genotype .
  • q² represents the frequency of homozygous recessive genotype .
  • 2pq represents the frequency of heterozygous genotype.

Number of homozygous dominant (YY) = 36

Number of homozygous recessive (yy) = 16

Number of heterozygous dominant (Yy) = 48

Total number of plants = 100

Now, frequency of homozygous dominant (YY) = 36/100 = 0.36

Therefore, p² = 0.36

So, p = √0.36 = 0.60

Hence, frequency of dominant allele (Y) = 0.60

Which process could cause a metamorphic rock to return to the surface of Earth to be worn down again? Please explain.
fenix001 [56]
This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment. These sediments could then be compressed to form sedimentary rocks, which would start the entire cycle anew.

Finger [1]

Answer: option D.

Explanation:

Enzyme are protein that act as catalyst in living organisms thereby regulating the rate of chemical reaction without itself being changed in the process.

Enzymes lowers the activation energy of a reaction because it not possible for it to affect the overall enthalpy of a reaction and in doing this they increase the rate of a reaction, helping it to occur faster.
