The correct answer is species B and C.

As you can see in the diagram presented below, all of the other species have a number of differences between their amino-acid sequences, but in the case of species B and C there are no differences. This implies a close evolutionary relationship between the two species.

RoseWind [281]

Answer:

148

Explanation:

According to Hardy-Weinberg equilibrium,

p + q = 1

p² + 2pq + q² = 1 where,

p = frequency of dominant allele

q = frequency of recessive allele

p² = frequency of homozygous dominant genotype

2pq = frequency of heterozygous genotype

q² = frequency of homozygous recessive genotype

Here,

Total population = 592

Number of NN people = 148

Frequency of N blood group or NN genotype (q²) = 148/592 = 0.25

q = √0.25 = 0.5

p = 1 - q

= 1 - 0.5 = 0.5

Hence, p = 0.5

Frequency of MM genotype = p² = 0.25

Number of people with MM genotype = 0.25*592 = 148

Hence, 148 people will have MM genotype or M blood group.

What part of a cell is the site of rrna synthesis, and is also responsible for the assembly of ribosomal subunits?
Kitty [74]

What area of a cell is the location of rRNA synthesis and is also in charge of ribosomal subunit assemblage?

What is rRNA?

Ribosomal RNA (rRNA), a molecule in cells that is transferred to the cytoplasm and is a component of the protein-producing organelle known as a ribosome, aids in the conversion of messenger RNA (mRNA) into protein. rRNA, mRNA, and transfer RNA are the three main forms of RNA found in cells (tRNA).

Nucleolus area of a cell is the location of rRNA synthesis and is also in charge of ribosomal subunit assemblage.
