Earth's carbon cycle maintains a stable climate and biosphere on geological timescales. Feedbacks regulate the size of the surface carbon reservoir, and on million锕渆ar timescales the carbon cycle must be in steady state. A major question about the early Earth is whether carbon was cycled ...
After a red giant of similar mass to our sun burns up all its helium, gravity has free rein to compress its core as far as the carbon electrons therein will permit. This great density creates enormous core heat. And because the core is all that's left at this point, core temperature i...

Explain the composition of cigarette smoke and why it has a negative effect on pulmonary health. Explain the carbon cycle. Describe how acetaminophen causes toxicity, especially in cases of overdose. What is pneumonia? Explain. What is the antidote for cyanide? Describe its molecular function. Desc...
Explain the role of photosynthesis and respiration in both the carbon cycle and movement of energy in the environment. Describe chemiosmosis as it relates to both photosynthesis and respiration. Describe the relationship between cellular respiration and photosyn...
We present a qualitative reasoning model of how plant colonization of land during the mid Paleozoic era (450-300 million years ago) altered the long-term carbon cycle resulting in a dramatic decrease in global atmospheric carbon dioxide levels. This model is aimed at facilitating learning and comm...
The gridded near-real-time fossil fuel combustion data that include lockdown-induced reductions in 2020 were obtained from https://carbonmonitor.org. The tropospheric NO2 concentration data from OMI satellite measurements were downloaded from https://disc.gsfc.nasa.gov/datasets/OMNO2_003/summary....
