Biology

Explanation:

The ultimate source of all genetic variation is mutation. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele. Recombination also can create a new DNA sequence (a new allele) for a specific gene through intragenic recombination.

What is the difference between climate change and climate variability ​
vaieri [72.5K]

Answer:

Climate change is the change of temperature in the worlds climate system and climate variability is the variations in a certain climate that last longer then  certain weather events.

Explanation:

To explain more climate change is the change in the daily weather in a area for example rain forest to desert or cold to hot climate change goes along with global warming which is the heating of our Earth which causes ice to melt in the arctic rising our sea levels creating stronger storms. While in a climate variability its only a certain time of that specific climate change for example its only cold for a certain period of time then the temperature rises to hot again. So, the key difference is that "climate change is the change of temperature in the worlds climate system and climate variability is the variations in a certain climate that last longer then  certain weather events."

Hope this helps!

When wind slows down, it deposits sediment. What feature is created by the deposition of loosely packed, mineral-rich soil?
tamaranim1 [39]

The feature that is created by deposition of the loosely packed and mineral-rich soil is Loess.

Loess is a loosely packed soil deposition due to blown wind of sediment rocks. The geography of loess is in between soil and clay. It is finer in texture than soil but has the coarse structure than the clay. This loess contains certain clay portions in order to hold the soil particles properly.

It can be mostly seen in Great Plains of North America, northern china, and other places around the world.
