Guinea, under the name French Guinea, was a part of French West Africa until it achieved independence in 1958. It then was ruled successively by Sékou Touré (1958–84) and Lansana Conté (1984–2008), the latter of whom claimed power through a military coup. (1984–2008), the latter of whom claimed power through a military coup.
Carbon Stock Density in Year 2017 = (57,546 MMT C × 10 6) / (273,623 thou. hectares × 10 3) = 210 metric tons of carbon stored per hectare Annual Net Change in Carbon Stock per Area in Year 2017 = (-141.2 MMT C × 10 6) / (273,623 thou. hectares × 10 3

Oxygen & Carbon Dioxide: Gas Exchange and Transport …
In this system, carbon dioxide diffuses into the red blood cells. Carbonic anhydrase (CA) within the red blood cells quickly converts the carbon dioxide into carbonic acid (H 2 CO 3 ). Carbonic acid is an unstable intermediate molecule that immediately dissociates into bicarbonate ions (HCO âˆ’ 3 ) and hydrogen (H + ) ions.
Carbon, in the form of carbon dioxide, is a greenhouse gas associated with global warming. So by increasing soil organic matter, more carbon can be stored in soils, reducing the global warming potential.
Carbon stores and cycles | Geography | tutor2u
2020/8/12· Carbon is integral to life on earth. It is found as carbon based molecules in various forms – as carbon dioxide and methane in the atmosphere, as organic matter in soils formed by the decomposition of organic material, sedimentary ocean bed layers, in carbon-rich rocks and in vegetation. The key carbon cycles operate at the terrestrial, atmospheric and oceanic level.
How Does Blood Get Oxygen? | Sciencing
Thus, the circulatory system in its entirety is a circuit. Red blood cells (erythrocytes) contain the complex, iron-based protein compound called hemoglobin. The erythrocytes, and the hemoglobin they contain, function to bind oxygen and carbon dioxide, releasing carbon dioxide into and picking up …

The ocean and the carbon cycle — Science Learning Hub
Carbon is a chemical element vital to all living things and is present in many non-living things. Carbon circulates around the planet in what is called the carbon cycle. Parts of the cycle store carbon for different lengths of time, and there are many processes that move carbon in and out of the stores.
