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.

What is a Lytic infection and What is a lysogenic infection?

expeople1 [14]

Answer:

Infection of a bacterium by a bacteriophage with subsequent production of more phage particles and lysis, or dissolution, of the cell. The viruses responsible are commonly called virulent phages. Lytic infection is one of the two major bacteriophage–bacterium relationships.

Lysogeny, or the lysogenic cycle, is one of two cycles of viral reproduction. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm.

What is the probability that the first offspring from the cross listed below will be heterozygous for all loci?

Tanya [424]

Answer and Explanation:

Cross: aa Bb dd Ee x AA bb Dd Ee

We can calculate the probability of getting heterozygous individuals in the progeny by using the product rule. Assuming that these four genes assort independently (events that occur independently from each other), we can infer that the F1 will have the next genotypic proportions for each gene:

1) aa x AA

F1) 4/4=1 Aa

2) Bb x bb

F1) ½ bb

½ Bb

3) dd x Dd

F1) ½ dd

½ Dd

4) Ee x Ee

F1) ¼ EE

2/4 = ½ Ee

¼ ee

So, to know what the probability is that the F1 of being heterozygous for all loci, we must multiply the respective individual probabilities of getting a heterozygous genotype, like this:

1 Aa x ½ Bb x ½ Dd x ½ Ee = 1/8 AaBbDdEe
