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
Yes, the statement is true.
Answer:
Natural resources are used to make food, fuel and raw materials for the production of goods. Natural resources such as coal, natural gas and oil provide heat, light and power.
In addition to endocrine glands, some organs whose functions are primarily nonendocrine also produce hormones. these endocrine tissues include heart and kidneys.
<span>
The heart can act as an endocrine organ by releasing natriuretic peptides that lower the blood pressure. Those are an A-type natriuretic peptide (ANP) from the from stretched atria and B-type natriuretic peptide (BNP) from the ventricles.</span>
<span>
The kidney secretes two hormones: erythropoietin (EPO) which increase the production of red blood cells and calcitriol (active vitamin D3) which promotes the absorption of Ca and its release from the bones.</span>
