The value of Q is 0.44 if 20 organisms of 100 organisms are green.

Explanation:

Data given:

alleles for the color of eyes of fly:

blue allele = dominant represented by P

green allele = recessive, represented by Q

total number of organism = 100

number of recessive trait organism, q^{2} = 20

Q =?

The allele frequency of the green eye is calculated as:

\frac{total number of recessive alleles}{total number of all alleles}

= \frac{20}{100}

q^{2}= 0.2

q = \sqrt{0.2}

q = 0.44

0.44 is the frequency of Q allele in the population.

Q is the homozygous recessive alleles in the population and its value is 0.44.

mixer [17]

Answer:

(08) and (32)

Explanation:

To make osmosis happen there has to be a difference in the concentration of solutes, between the inside and the outside of the cell. To valance this difference in concentration, water has to flow towards a place that has a higher number of solutes.

The lipids in the cell's wall make this membrane semipermeable. This allows the passage of specific components only, such as water through aquaporins. Lipids and other elements are of importance in the barrier because they maintain the cell separated from the outside, allowing it to be balanced as regards the different substances that can interact with it.
