Answer:

C. Inorganic Fertilizers

Explanation:

No inorganic fertilizers on earth contain cycle participating carbon. The only carbon containing fertilizer is organic Urea (NH2CONH2). This is because plants are never deficient in organic carbon availability. The inorganic fertilizers only deal with their mineral need and that;s why they don't participate in carbon cycle.

What important process happens at the capillaries?
Zarrin [17]

Answer: Capillaries connect the arterial system — which includes the blood vessels that carry blood away from your heart — to your venous system. Your venous system includes the blood vessels that carry blood back to your heart. The exchange of oxygen, nutrients, and waste between your blood and tissues also happens in your capillaries.

Describe and explain how blood flows from the foot to the lungs.
Natali5045456 [20]

Answer:

lungs:

The blood first enters the right atrium.

The blood then flows through the tricuspid valve into the right ventricle.

When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.

The pulmonary artery carries blood to the lungs where it “picks up” oxygen.

It then leaves the lungs to return to the heart through the pulmonary vein.

The blood enters the left atrium.

It drops through the mitral valve into the left ventricle.

The left ventricle then pumps blood through the aortic valve and into the aorta. The aorta is the artery that feeds the rest of the body through a system of blood vessels.

Blood returns to the heart from the body via two large blood vessels called the superior vena cava and the inferior vena cava. This blood carries little oxygen, as it is returning from the body where oxygen was used.

The vena cavas pump blood into the right atrium and the cycle begins all over again.
