Answer:
Incidence of cystic fibrosis on the island= 0.0025
Explanation:
According to the given information, the population is in Hardy Weinberg equilibrium which means that the allele frequencies would be maintained over generations.
Given that total population size is = 20
Total number of alleles = 20 x 2 = 40 (since human are diploid, each individual has two alleles for one gene).
Out of total 19 people, only two are heterozygous for cystic fibrosis which means that out of total 40 alleles, the number of recessive allele for cystic fibrosis is = 2
Frequency of recessive allele (q)= 2/ 40 = 0.05
Frequency of cystic fibrosis genotype (q^2) = 0.05 x 0.05 = 0.0025
Therefore, incidence of cystic fibrosis on the island would be = 0.0025
Splash large amounts of water to dilute the spill. Stand back and advise the teacher of the spill. Immediately ask to go to the restroom.

Explanation:
<h2>In order to do photosynthesis, a plant needs sunlight, carbon dioxide (CO2) and water. Once the sugar is made through photosynthesis, it is then broken down by the mitochondria to make Page 2 energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.</h2>
What are you talking about
A demarc is where one network ends and another begins. Demarc stands for demarcation point. It is the physical point at which the public network of a telecommunications company ends and the private network of a customer begins.
However, the distinction between where one category of network begins and another ends is sometimes blurry.
