Answer: B. right atrium --> right ventricle --> left atrium --> left ventricle

Explanation: Deoxygenated blood enters the superior vena cava and inferior vena cava and collects it on the right atrium. It is then pumped up through a valve and enters the right ventricle. Then it is transported by the pulmonary artery to the lungs to become oxygen rich blood. From the lungs oxygenated blood enters into the pulmonary vein and back into the heart and goes inside the left atrium. The blood is pumped again through a valve going to the left ventricle and transported to the body through the aorta which distributes oxygen rich blood.

solniwko [45]

Answer:

Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.

In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .

Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.

These compounds interact with one another and end in “life”.

So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.
