Explanation:
Answer: The correct answer would be gene pool.
Explanation:
Gene pool refers to the sum of all the alleles in an individual.
The allele refers to the alternate forms of the gene.
Large population usually has more genetic diversity as compared to small population. Variation in gene pool is essential for survival of a population.
Answer:The ratio of the concentrations of
and
when the buffer has a pH of 7.02 is 0.69
Explanation:
The dissociation constant for formic acid =
Concentration of HA= 0.5 mM
Concentration of
= 0.1 mM
pH = 6.16
First we have to calculate the value of
.
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
To calculate the ratio of the concentrations of
and
when the buffer has a pH of 7.02.
Using Henderson Hesselbach equation :
Thus the ratio of the concentrations of
and
when the buffer has a pH of 7.02 is 0.69
