In a population of rabbits, there are 496 black rabbits and 27 white rabbits. Fur color is determined by a pair of alleles where
Troyanec [42]

Answer:

0.96

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is 0.8

As per Hardy Weinberg's  first law of equilibrium

p + q = 1\\

Substituting the value of p in above equation, we get -

q = 1-p\\q = 1-0.8\\q= 0.2

q represents the frequency for white fur allele

Frequency of white fur phenotype is

q^2\\= 0.2^2\\= 0.04

Frequency of homozygous black fur phenotype (BB) is

p^2\\= 0.8^2\\= 0.64

As per Hardy Weinberg's second law of equilibrium -

p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\

Combined frequency of homozygous and heterozygous black fur phenotype is

0.64 + 0.32\\= 0.96

Look at the reaction below.
Ray Of Light [21]

Answer:

Ca(OH)2 (aq)

Explanation:

The balanced neutralization reaction i.e. a reaction between an acid and a base, in this question is given as follows:

H2SO4(aq) + Ca(OH)2(aq) → CaSO4(aq) + 2H2O(l)

According to Arrhenius in his definition of acid and base, a base is a substance that dissociates into hydroxide ions (OH-) when in an aqueous solution. In other words, a base increases the concentration of hydroxide ions when dissolved.

In this reaction, Ca(OH)2 releases the OH- (hydroxide ion) that combines with the hydrogen ion (H+) released by the acid, H2SO4, to form water (H2O). Hence, Ca(OH)2 (aq) is the BASE.
