The sequential events in the Arctic ecosystem feedback loop are: Global temperature increases → permafrost thickness decreases → methane increases → global temperature increases. It is harmful to the Earth.
The Arctic ecosystem is a feedback loop because the warmer the temperatures, the less sea ice (permafrost) is observed.
The Arctic ecosystem feedback loop is a dangerous phenomenon because it accelerates global warming.
Permafrost refers to ice ground that remains completely frozen (0°C) for at least two (2) or more years straight.

Astrocytes can be defined as one of the cell types in the central nervous system. These are the dominant glial cell found in the brain. These cells perform a variety of functions in the brain. The functions includes axon guidance, synaptic support, controlling the blood brain barrier and blood flow. These cells maintain the chemical environment in the brain especially around the neuron.
These cells do not provide to the central nervous system.
The answer is B, fossil fuels take a long time to form and humans use lots of them everyday
<span>Members of the archaea are complex single-cells organisms that are often thought to be bacteria; however, they are actually prokaryotic microbes that lack a cell nucleus and membrane. They often thrive in extreme conditions such as extreme heat.</span>
Answer: wherever the wind blows :)
Explantation: the waves go 90 degrees to the left (southern hemisphere) or the right (northern hemisphere)
also, if it's blowing away from the beach, it causes upwelling,
which brings nutrients from the bottom of the ocean and attracts more organisms.
hope this helps :)
