Answer:
nitrogen cycle
Explanation:
Nitrogen enters the living world by way of bacteria and other single-celled prokaryotes, which convert atmospheric nitrogen— N 2 \text N_2 N2start text, N, end text, start subscript, 2, end subscript—into biologically usable forms in a process called nitrogen fixation.
Convection cell in the sun's rays are the ones that carry energy to travel within its surface and outside.
There are three types of heat transfer or heat propagation; conduction, convection and radiation. Heat transfer is the process by which heat projects externally however, depending on the temperature and pressure. Also called the movement of heat from a low temperatured state which increases as heat progresses.
Conduction is the heat transfer by contact, immediate contact.
Convection is the transfer of heat through air and water.
<span>Radiation is the transfer of heat regardless of the presence of atoms or particles. </span>
Answer:
Both processes rely on blood circulating throughout the body.
Blood is oxygenated in the lungs. The blood carries the oxygen to tissues, where the oxygen is released so that tissues can use it for cellular respiration. At the same time, carbon dioxide waste produced by the tissues enters the blood and is carried back to the lungs to be exhaled. At the same time, fresh oxygen enters the blood and the cycle begins again.
This is a very general explanation but I can explain in more detail if needed.
