The cell membrane... is made of phospholipids (consist of a lipid bilayer)
erma4kov [3.2K]4 years ago

Answer:

Is made of phospholipids

Explanation:

The cellular compartment of all eukaryotes is bounded by a membrane called cell/plasma membrane. The membranes in cells are similar in structure and majorly composed of phospholipids that builds it.

The phospholipid component are arranged in two adjacent layers in biological membranes, hence, called phospholipid bilayer. The phospholipid bilayer is said to be AMPHIPATHIC because it contains two hydrophobic fatty acids and a hydrophilic phosphate head in its structure. This amphipathic nature of the cell membrane confers semi-permeability of substances upon it.

How are alleles and traits related?
Katen [24]
<span>Alleles are each of two or more alternative forms of a gene that are found at the same position in a chromosome. Traits on the other hand, are the characteristics that are defined by genes. So the combination of alleles for a gene is what manifests itself into a trait.</span>

Suppose a population is carrying a condition controlled by two alleles: R (dominant) and r (recessive). Only homozygous individu
White raven [17]

<span><u>The answer is A. 72.25 percent.</u>

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>r</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>R</em> allele frequency (<em>p</em>), the formula p + q = 1 is 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>R</em> allele (<em>p</em>), it is easy to determine the frequency of the RR genotype (p²):
p² = 0.85² = 0.7225

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