Answer:

B

Explanation:

This number that is put in a compound is called a subscript. It is put in front of the symbol of the element being represented. An example is CO₂ which means there are one (1) carbon and two (2) oxygen atoms in the compound.

Suppose a population is carrying a condition controlled by two alleles: P (dominant) and p (recessive). Only homozygous individu
Virty [35]

<span>The answer is B. 72.25 percent.

The Hardy-Weinberg principle can be used:</span>

<em>p² + 2pq + q² = 1 </em>and <em>p + q = 1</em>

where <em>p</em> and <em>q</em> are the frequencies of the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq</em> are the frequencies of the genotypes.

<span>The <em>p</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15

To calculate the <em>P</em> allele frequency (<em>p</em>), the formula <em>p + q = 1</em> can be used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85

Knowing the frequency of the <em>P</em> allele (<em>p</em>), it is easy to determine the frequency of the <em>PP </em>genotype (<em>p²</em>):
p² = 0.85² = 0.7225

Expressed in percentage, p² = 72.25%.</span>

An animal cell lacking carbohydrates on the external surface of its plasma membrane would likely be impaired in which function?
PilotLPTM [1.2K]
An animal cell lacking carbohydrates on the external surface of its plasma membrane would likely be impaired in CELL TO CELL RECOGNITION.
Carbohydrates have diverse functions, one of their functions is that they serve as a recognition signal at the surface of cells.
Carbohydrates located on the surface of cells enable cells to recognize and  communicate with one another.

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.
