Answer:

Crossing over.

Explanation:

Crossing over is the process of exchange of genetic material between two non-sister chromatids of a homologous chromosome pair. It occurs during pachytene of prophase I of meiosis I. Crossing over creates new gene combinations that were otherwise not present in the parent cells. In this way, genetic variations are created by crossing over.

What type of human activities cause the elevation of atmospheric greenhouse gases
Leto [7]
The amount of greenhouse effect on Earth is directly proportional to the concentration of greenhouse gases in the atmosphere. In this era of industrialization, although it may seem that it has greatly improved the global economy, it also downplays the importance of consistently upholding our role as a steward to Earth. 

The most common types of human activities that continuously worsen the greenhouse effect are: burning of fossil fuels, agriculture, and industrial processes.

The burning of fossil fuels such as coal, oil, and gas emits carbon dioxide which accounts for approximately three-quarters of the warming impact caused by the greenhouse gas emissions. This is amplified significantly through deforestation. 

Methane, which accounts for 14 percent, and nitrous oxide, which accounts for eight percent are one of the major greenhouse gas emissions on earth. This can be sourced out from livestock and rice fields and also fossil fuel extraction and organic waste decay in landfill sites.

Industrial processes would incept fluorinated gases which accounts for one percent of the warming effect of current human greenhouse gas emissions.

Although it may seem that the values are not that high, but it must also be taken into consideration the several or a superfluous number of industries all around the world that simultaneously worsens the already groveling site of the continuously deteriorating and exploited planet Earth.

What are some positive effects humans can have on nitrogen cycle
inn [45]

Answer:

Scientists have determined that humans are disrupting the nitrogen cycle by altering the amount of nitrogen that is stored in the biosphere. The chief culprit is fossil fuel combustion, which releases nitric oxides into the air that combine with other elements to form smog and acid rain.
