Respiration is an catabolic process in which the organic compounds are oxidized to release energy, carbon dioxide and water. The liberated energy is stored in the ATP molecules (adenosine triphosphate), which are the energy currency of the cells. The four basic processes involved in respiration are-
(1) Pulmonary ventilation or breathing- It is the process of inflow of air into the lungs from the atmosphere (inspiration or inhalation) and outflow of air from the lungs to the atmosphere (expiration or exhalation). It is due to the difference in the air pressures according to the principle of Boyle's law.
(2) External respiration- It is the process of exchange of the oxygen and carbon dioxide between the inhaled air in the alveoli of the lungs and the deoxygenated pulmonary blood.
(3) Internal respiration- It is the process of exchange of gases between the oxygenated blood and the tissue cells of the body.
(4) Cellular respiration- It is the process of oxidation of the respiratory substrates like glucose inside the cells.
Thus, the four processes of respiration include the pulmonary ventilation, external respiration, internal respiration and cellular respiration.
Answer: lets say all you have to do is look around when your outside and look at the dirt or something and think ' how did it get here' was a man-made or natural.
Explanation:
pls put me brainiest!!
Answer:

Answer:
Musculoskeletal System is the system of the body which perform the important function of the body like helps in the movement of the body, provide the shape and support to the body.
The system is formed by two different systems of the body which are the skeletal system and the muscular system.
The skeletal system protects the internal structure of the body but the muscular system which are attached to the skeletal system and increases the efficiency of the functions performed by the skeletal and muscular system. Both of this system work together to perform the same functions.
I’m not 100% sure but normally the codons are paired in 3s, so my guess is B lmk what the answer was:)
