arlik [135]3 years ago
7 0

The size of the nucleus of an atom is about 10 raise to power 15 meter, which basically proposes that it is about 10 raise to power -5 or 1/100,000 we can say of the size of the entire atom. A good comparison of the nucleus to the atom is just like a pea in the midst of a track. The volume of the atom is 2 x 1013 times larger than its nucleus.

Learning objective: 12.08.05 describe the initiation and propagation of depolarization and repolarization.
denis-greek [22]
Depolarization is initiated when there is an influx of sodium inside the cell as opposed to repolarization, where potassium exits the cell (occurring after Na+ gates close). Remember that for every 3 Na+ in, there is 2 K+ out. This imbalance helps to stabilize the membrane.

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
