Trava [24]

Answer:

0.25%

Explanation:

20 people start the new population. So there are 20 genes or 40 alleles for the recessive disorder phenylketonuria. 2 out of 40 alleles are recessive for the condition hence frequency of the allele = 2/40 = 0.05

Frequency of the allele does not change when the population increases so it is in Hardy-Weinberg equilibrium. According to it, if q is the frequency of recessive allele, q² = frequency of the recessive condition

Here, q = 0.05 So,

q² = (0.05)² = 0.0025

In percentage, it is 100 * 0.0025 = 0.25%

Hence, incidence of phenylketonuria in the new population is 0.25%

Determine what organism fits the following niche: Heterotroph, non-motile, spores.
Dahasolnce [82]

Answer:

C. Fly Cap mushroom

Explanation:

All fungi are heterotrophic organisms because they obtain food and energy from external sources. Moreover, fungi are non-motile since they don't move. Finally, these organisms produce both sexual and asexual spores which are dispersed by wind and water.  

On the other hand, the mushroom is the body of a fungus that grows on the soil, generally in humid and shady areas. The fly agaric mushroom is one of the most recognizable species of fungus.
