Explain how genes are expressed for a particular reason
ozzi

Each cell expresses, or turns on, only a fraction of its genes. The rest of the genes are repressed, or turned off.

The turned on genes are then first transcribed into messenger RNA by the process of Transcription.

Then the mRNA is Translated into protein by the process called Translation.

This is how the specific genes are expressed.

This is an advantage of which map projection? They are similar to the actual spherical surface of the globe.
lisov135 [29]

Answer:

Azimuthal map projections

Explanation:

The Azimuthal map projections come in a circular shape. They represent the whole world but in a different manner than that of the other map projections. The other map projections tend to have problems with the size of the objects as they get further away from the Equator, but this map projection doesn't have that problem. The Azimuthal map projections actually represent all of the places on Earth with their correct distances from the central point, and they all have their sizes correct proportionally to the scale, thus making an accurate map projection.

Chlorine in the stratosphere is believed to come primarily from cfcs rather than from natural sources such as volcanoes because:
Andreyy89

 he answer is because <span>samples of air taken over erupting volcanoes shows that volcanoes contribute a small amount of chlorine in the stratosphere compared to CFCs. Volcanic eruptions account for a large instability of chlorine from land to the atmosphere on a yearly basis. This is in addition to chlorine that enters the atmosphere from sea spray, industrial processes and biological gases which are from CFCs. All of these inputs happen near or at the base of the atmosphere. Very little of the material emitted from volcanoes makes it up into the upper reaches of our atmosphere which is the stratosphere where it could touch the ozone layer. However, most of it is believed to be deposited lower down which is in the troposphere, where it then rained out back to the surface of the earth.</span>
