ollows: Elevated atmospheric CO2 levels cause the climate to warm, thawing permafrost. Nitrogen mineralization is then stimulated as thawed permafrost decomposes. The resulting increase in soil ammonium then stimulates primary production, which pulls CO2 from the air. What kind of feedback loop is described

Answer:

The kind of feedback loop described above is:

a negative feedback loop.

Explanation:

A negative feedback loop causes homeostasis.  A negative feedback loop tends to stabilize the ecosystem, creating some balance.  Positive feedback loops, on the other hand, enhance or amplify changes, moving the system away from its equilibrium state, and making it unstable.  With negative feedback loops, changes are dampened or buffered.  This causes the system to maintain some equilibrium or remain in a stable state.  All homeostatic systems, such as thermoregulation (which regulates the body temperature) and blood sugar regulation, operate on negative feedback loops.

andrey2020 [161]
<span>mtDNA analysis is the best DNA technology to use. In DNA fingerprinting scientists run a gel electrophoresis of the subject's DNA in order to establish the banding patterns of the DNA fragments. People will always share half of their DNA with a parent. SO half of an individual's banding pattern will match half of their parent's DNA banding pattern. If someone is missing is found then scientists can compare the DNA fingerprint or banding patterns to see what the likelihood is of them being related.</span>

Identify the product of seafloor spreading.
Serjik [45]
D. Volcanic Rock

As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.
