What are auroras made of?

Biology
1 answer:
bagirrra123 [75]3 years ago
8 0

Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere) due to Earth's magnetic field, where their energy is lost.

The resulting ionization and excitation of atmospheric constituents emits light of varying color and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes.

Ethanol is a domestically produced alternative fuel most commonly made from corn. ... such as crop residues and wood—though this is not as common.Ethanol is one example of alternative fuels for powering our cars and trucks. Ethanol can be produced in different ways, but most often by microorganisms acting on plant materials such as corn.

If a Tt plant is crossed with a Tt plant, what is the chance that a tt offspring will be produced? 75% 25% 50% 100%
adoni [48]

Answer: the correct answer is 25%

T is the allele for tall plant, which is dominant trait. 't' is the allele for dwarf plant, which is a recessive trait.

Genotypes of the parent plants are- Tt and Tt. When they are crossed, there are 25% chances of producing tt offsprings. Refer the punnett square for this.

% of Offsprings with tt genotype = \frac{1}{4} \times 100

                                                      =  25%
