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.

How do ocean currents influence the climate of a place?
iragen [17]
When currents happen little waves are being pushed toward the shore or away from the shore. When being pushed toward the shore cool air is being blown toward land making the air cooler. for exaple the air near a beach will be cooler at night because of ocean breeze

Movement of chromosome segment to a non-homologous chromosome. This type of chromosomal mutation occurs when one chromosome swap
Hitman42 [59]

Answer:

The correct answer is ''Translocation​.''  

Explanation:

Translocation is a chromosomal abnormality that is due to a change in position of a chromosomal segment to another non-homologous chromosome of the same nucleus or to another part of it. It is produced by the exchange of segments between two chromosomes without loss of genetic material is called reciprocal or balanced translocation, when it gives rise to monocentric chromosomes.Translocations can be detected cytologically because the structural heterozygote forms a quadrivalent (4-chromosome association) in meiotic prophase. Sometimes they can also be detected by changes in the size of the chromosomes if the exchanged segments are of different lengths.
