I would say photosynthetic bacteria are the most important, because if they disappeared most of the oxygen in the atmosphere wouldnt be here and complex life like humans wouldnt exist
Answer: Vena cava also know as (SVC).
Explanation: Blood provides oxygen and nutrients to the body and removes carbon dioxide and wastes. Oxygen-poor blood returns from the body to the heart through the superior vena cava also know as (SVC) and also inferior vena cava (IVC), these are the two main veins that bring blood back to the heart.

While magma rises to the surface the pressure drops and the gases start to separate out.

Magma is a blend of liquid or semi-liquid shake, volatiles, and solids that are found underneath the surface of the Earth. The gases are caught under in magma and after that, they r in colossal weight. As magma ascends to the surface the weight diminishes and the gases start to isolate out.
Okay, first of all, I don't know what "do we live in" means. I am guessing you're talking about the <u>United States</u>.
We live in the Prevailing Westerlies, which blow in the middle latitudes. Most of North America fits into this belt.
Defibrillation is a method of emergency medicine that can stop ventricular fibrillation or pulseless ventricular tachycardia. An electricity is used to reset the electrical state of the heart so that heart beat will have rhythm controlled by its pacemaker. This is not used in asystole and pulseless electrical activity. Defibrillator is used to give an electric shock to the heart. This depolarizes the muscles in the heart which stops the dysrhythmia, the SA node can eventually produce its own electrical impulse which establish the normal sinus rhythm of the heart. Cardioversion can also be done to provide normal rhythm in poorly perfusing cardiac dysrthymias.
Defibrillators can be implanted, external, transvenous depending on the type of devide used or needed in the current situation.
