A tree frog population lives in the canopy of a tropical rain forest. In this tree frog population, a mutation occurs that results in a new allele for skin coloration
causing stripes on their legs. Which of the following factors has the greatest effect on
whether leg stripes will become more common in the tree frog population?

1. If the new allele for stripes increases the survival of the tree frogs in their environment.

2. If the reproduction rate of the tree frog population remains constant over time.

3. If the new allele for stripes is presented more in females in the tree frog population.

4. If enough food and water are available in the rain forest canopy for the tree frog population.

pls help its a test

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
