<h2>Answer:</h2>

Valves prevent the backward flow of blood.

<h2>Explanation:</h2>

The heart consists of two atria (upper chambers) and two ventricles (lower chambers). There is a valve through which blood passes before leaving each chamber of the heart. In case of veins, valves keep blood moving in one direction: back toward the heart. For example when the leg muscles are activated, the venous valves open to allow one-way flow in the direction of the heart.

Answer:

It looks to me that those are plant genes. And plant genes use the atmosphere and the hydrosphere to take in carbon dioxide. CO2 is in the atmosphere and once consumed, sugar ( Glucose ) is created. H2O is part of the hydrosphere and when water is consumed, Oxygen is the output. All of the spheres of the earth ( biosphere, hydrosphere, geosphere, and atmosphere ) are interconnected to create the things we know and see.
