Because it has reached the stage of a noble gas
Most copper compounds tend to settle down near the water sediments or near the soil particles and can be monitored from there.
<u>Explanation:</u>
Copper can be discharged into the earth by both natural sources and human exercises. Copper is regularly found close to mines, modern settings, landfills and waste removals. Most copper mixes will settle and will undoubtedly either water silt or soil particles.
Copper doesn't separate in the earth and due to that it can gather in plants and creatures when it is found in soils. At the point when the dirt of farmland are dirtied with copper, animals will assimilate fixations that are harming to their well being.

Answer:
chromosomes, the X and the Y.
Explanation:
Egg cells all contain an X chromosome, while sperm cells contain an X or Y chromosome. This arrangement means that it is the male that determines the sex of the offspring when fertilization occurs.
The most probable future changes in the global climate are:
- Global warming;
If the levels of CO2 and methane increase enough in the atmosphere to be able to intensify the Greenhouse effect, than some portion of the ice on the planet will melt because of the rising temperatures, thus lifting up the sea level, creating more unpredictable weather with larger and stronger storms, but also making the mainland much drier. This would be a scenario if the continents are arranged like they are now, but if there isn't a sufficient mass of land on and around the poles, than all of the ice will melt and the sea levels will rise so much that the planet will come in the ''water planet'' scenario, and it will have wet tropical climate pretty much everywhere on the planet.
- Ice Age;
If there's a disruption in the warm ocean streams and some of them disappear, or the levels of nitrogen or oxygen increase in the atmosphere, the Earth will start to cool off, thus coming to a situation of an Ice Age. In this kind of situation, there will be large ice sheets on and around the poles that are stretching much further towards the lower latitudes, as well as mountains all over the world that are covered in snow and shaped by glaciers.
