Answer:

The lower pressure balloon will expand. Figure 2 (above left) shows a typical initial configuration: the smaller balloon has the higher pressure. So, when the valve is opened, the smaller balloon pushes air into the larger balloon. It becomes smaller, and the larger balloon becomes larger.

Hope this is helps out

Paul [167]

Answer:

frequency of the blue (B) allele = 0.4142

frequency of the red (R) allele = 0.5858

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142

Frequency of other allele

1- 0.4142\\= 0.5858

Chi Square test

See the attached file

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97
