Cellulose, chitin, and the polysaccharide that makes up the cell walls of many bacteria are the structural polysaccharides, wher
Harrizon [31]

Answer:

B

Explanation:

Wall cell has to be strong to bring protection to the cell. In general it is made of beta-glycosidic bonds.

Storage polysaccharides, are a source of available energy for the cell in any moment. Therefore, the bonds of storage polysaccharides need to be weak. In that way, when the cell needs energy from carbohydrates, it is not going to spend so much energy trying to break the bond.

In a population of cats, the phenotypic frequency of black cats is 91%, and the phenotypic frequency of white cats is 9%. Assumi
Talja [164]

Answer:

1. Allele frequency of b = 0.09 (or 9%)

2. Allele frequency of B = 0.91 (0.91%)

3. Genotype frequency of BB = 0.8281 (or 82.81%)

4. Genotype frequency of Bb = 0.1638 (or 16.38%)

Explanation:

Given that:

p = the frequency of the dominant allele (represented here by B)  = 0.91

q = the frequency of the recessive allele (represented here by b)  = 0.09

For a population in genetic equilibrium:

p + q = 1.0 (The sum of the frequencies of both alleles is 100%.)

(p + q)^2 = 1

Therefore:

p^2 + 2pq + q^2 = 1

in which:  

p^2 = frequency of BB (homozygous dominant)

2pq = frequency of Bb (heterozygous)

q^2 = frequency of bb (homozygous recessive)

p^2 = 0.91^2 = 0.8281

2pq = 2(0.91)(0.9) = 0.1638
