Ciclo del Carbono
Un 18% de la materia orgánica viva está constituida por carbono, la capacidad de dichos átomos de unirse unos con otros proporciona la base de la diversidad molecular así como el tamaño molecular. Por tanto el carbono es un elemento esencial en todos los seres vivientes.
A parte de la materia orgánica, el carbono se combina con el oxígeno para formar monóxido de carbono (CO), dióxido de carbono (CO2), también forma sales como el carbonato de sodio (Na2CO3), carbonato cálcico (en rocas carbonatadas, como calizas y estructuras de corales).

Apart from organic matter, carbon combines with oxygen to form carbon monoxide (CO), carbon dioxide (CO2), it also forms salts such as sodium carbonate (Na2CO3), calcium carbonate (in carbonate rocks, such as limestone and coral structures).

True!
Arteries carry oxygen-rich blood from the heart to capillaries. On the contrary, veins carry blood without oxygen from the capillaries to the heart.
Arteries are very flexible and yet strong blood vessels so efficient transport of oxygen-rich blood through the organism is performed.
Answer:
The correct answer is d . vena cava â right atrium â right ventricle â pulmonary artery
Explanation:
Normally blood from the inferior vena cava enters the right atrium, then it passes to the right ventricle then to the pulmonary artery that takes it to the lungs and back to the left atrium via the pulmonary veins and then to the left ventricle and then to the aorta and finally to systemic circulation.
