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, andindustrial 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.
A localised group of organisms that belong to the same species is called Population. This can be a local population if the organisms stay at a particular place or a metapopulation if the organisms tend to move from one geographical location to another.
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I. D
