The right atrium receives the de-oxygenated blood from the body. From the right atrium blood passes to the right ventricle.
The right ventricle propels this de-oxygenated blood to the lungs though pulmonary artery, for oxygenation. The deoxygenated blood loses carbon-di-oxide and gains oxygen in the lungs. This process is called gaseous exchange.
After the gaseous exchange, blood becomes oxygenated. This oxygenated blood comes to left atrium of the heart through pulmonary veins.
From the left atrium blood comes to the left ventricle. Left ventricle sends this oxygenated blood through aorta and arteries to all organs of the body.

True, producers produce their own energy. Consumers consume it.
We defined secondary consumers<span> as organisms, primarily animals, which eat primary </span>consumers<span>. Furthermore, </span>secondary consumers<span> can be classified into one of two groups: carnivores, or meat eaters, and omnivores, which are plant and meat eaters.
So the answer would be D.</span>
Knowing proteases being essential for replication of a virus
would suggest the virus contains at least one polyprotein. The family of
reoviruses has dsRNA genomes that replicate from the template of only the
positive ssRNA strand which makes it a conservative replication process.
