Describe how climate would be influenced if:
madam [21]
  1. The rate of energy coming from the Sun changes slightly day to day. .It has been suggested that changes in solar output might affect our climate—both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes.
  2. The axial tilt angle affects climate largely by determining which parts of the earth get more sunlight during different stages of the year Likewise, during winter for the northern hemisphere, there would be fewer hours of daylight because the northern hemisphere would essentially be pointed away from the sun.
  3. If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere, blocking the radiation from the Sun. This would cause the global temperature to decrease drastically.
  4. The Sun's irradiance has its greatest effect on Earth's upper atmosphere, while the lower atmosphere insulates Earth from the increased heat. If the Sun were driving Earth's warming, one would expect to see that upper atmosphere getting increasingly hot.\

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

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
