A population of wild-flowers was scored for flower color. There were 302 blue (BB) plants, 1857 violet (BR) plants and 811 red (
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

Following a meal glucose must move from the gut lumen where there is a high glucose concentration into the intestinal cell where
Alchen [17]

This movement from a high concentration area to a low concentration are is called Active transport.

<h3>Active Transport</h3>

Active transport by definition is a process that is characterized by the movement of molecules against a concentration gradient. Additionally, this process requires energy.

As in the question above, glucose molecules have to be moved across the gut lumen of higher glucose concentration to the intestinal cells of relatively low level of glucose.
