<h2>Answer:</h2>

Microwaves; X-rays


<h2>Explanation:</h2>

Microwaves are a type of electromagnetic radiation with wavelengths going from around one meter to one millimeter; with frequencies between 300 MHz (1 m) and 300 GHz (1 mm)Microwaves are a type of electromagnetic radiation with wavelengths going from around one meter to one millimeter; with frequencies between 300 MHz (1 m) and 300 GHz (1 mm)

X-rays make up X-radiation, a type of electromagnetic radiation. Most X-beams have a wavelength going from 0.01 to 10 nanometers, comparing to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) and energies in the range 100 eV to 100 keV

Microwaves are low energy waves found in the electromagnetic spectrum and X-rays are high energy waves found in the electromagnetic spectrum.

Electromagnetic radiation is described in terms of a stream which is of mass-less particles which are referred to as protons. At the speed of light, the photons travel in a wave-like pattern. Each proton has a certain amount of energy. The amount of energy which is found in protons is defined by different types of radiation. Radio waves they have protons which are low in energy together with microwave protons while ultraviolet, x-rays have more protons and the most energetic is gamma-rays.

Which process can increase the rate of greenhouse gas emissions into the atmosphere in response to a decrease in albedo?
Vesnalui [34]

B. Ice-albedo feedback

Explanation:

The ice-albedo feedback is one process that can significantly increase the rate of greenhouse emissions in response to a decreased albedo.

Albedo is the ratio of reflected light to incident light.

A decrease in albedo suggests that a surface is absorbing more light than it is reflecting. This is typical of areas with land cover and vegetation.

Areas with a high reflectivity have a high albedo. Snow, ice and polar regions are good reflectors of solar radiation. They have a very high albedo close to 100%. Much of the surface area is buried with ice.

Examples of greenhouse gases are carbon dioxide, methane, water vapor e.t.c

How does a low albedo relates to increase in greenhouse gas emission?

  • The ice-albedo feedback can substantially contribute to greenhouse gas emission.
  • The high reflectivity of ice causes long wave radiation to warm the air around a icy body in polar regions.
  • When ice melts, they leave land bare and exposed.
  • Melt water collects in pockets.
  • Exposed land leads to a decrease in albedo.
  • Organisms can thrive more in warm terrain.
  • Also, pockets of carbon dioxide gases trapped in ice is released.
  • Organisms release carbon dioxide into the atmosphere during cellular respiration.
  • Soils originally permafrost will become stable and this will encourage more human occupation of the area.
  • All these activities leads to an increase in the emission of greenhouse gases in an area with low albedo.

Normally, wild violets have yellow petals with dark brown markings end erect stems. Imagine you discover e plant with white peta
Wittaler [7]

Answer:

It is fascinating to observe two distinct characters presented by the same plant. The inheritance of this plant can be determined easily by crossing the pure violets exhibiting yellow petals with dark brown marking and erect stems with violets exhibiting no markings, white petals, and prostate stems.  

The F1 progeny will originate as a hybrid of the two characters. These F1 plants will then be crossed between themselves and the F2 progeny would be clearly evaluated. If the F2 plants come in the phenotypic ratio of 3: 1, then it would indicate the pleiotropic effect of the alleles found in a single locus. If any other combinations arise post crossing, it would indicate that the non-wild type phenotype is because of many distinct mutant genes.
