The Earth's system is divided in four subsystems: land (lithosphere), water (hydrosphere), air(atmosphere) and living things (biosphere).
Carbon is sixst most common chemical element on Earth.
<span>The most carbon on Earth is stored in a surprising place: the ocean.</span><span>This means that the most of carbon is stored in the lithospehere.

Carbon is most abundant in the core and in the atmosphere.
Answer:
The right atrioventricular valve (tricuspid) regulates the opening between the <u>right atrium</u> and the <u>right ventricle</u>.
Explanation:
Valves are gates that allow the connection between atria and ventricles. The two valves located on the right side (tricuspid and pulmonary) direct the incoming blood from the body to the lung, where it is oxygenated; from there it returns to the left atrium, to later pass through the mitral and aortic valves. The left atrium connects to the left ventricle through the mitral valve and the right atrium connects to the right ventricle through the tricuspid valve.
Answer:
Here's what I get
Explanation:
Per the above explanation, pH means "power of hydrogen ions."
The concentration of hydrogen ions is a measure of the acidity of a solution. A higher concentration represents a more acidic solution.
The definition of pH is
pH = -log[H⁺]
Thus, pH is a measure of the hydrogen ion concentration.
The more negative the pH, the greater the Potenz of hydrogen ions.
