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.

All living cells must maintain homeostasis or internal stable conditions in order to survive. Which of the following processes w
xenn [34]

Answer:

None of the options provided is correct but some are close

Explanation:

One of the ways in which a cell maintain homeostasis is by regulating what goes in and out of the cell through the cell membrane (which is a semi-permeable barrier). The amount of water is highly regulated by the cell in this case so as to regulate osmosis (movement of water molecules from a region of higher concentration to a region of lower concentration). Other substances regulated are oxygen and carbon dioxide.

NOTE: The cell <u>does not create water molecules neither does it use carbon dioxide to maintain homeostasis</u>, it rather regulates these two compounds.

kogti [31]
It seems that you have missed the given options for this question, but anyway, here is the answer. We are constantly bombarded by a variety of stimuli inside and outside of our bodies but we are not overwhelmed by sensory information because a<span> very tiny percentage of incoming sensory information is received by the cerebral cortex.
