The right atrium receives blood returning from others parts of the body through the superior vena cava and the inferior vena cava.  

Explanation:

The pathway of circulation begins in the right atrium which receives the carbon dioxide-rich deoxygenated blood returning through the systemic circulation.  

The deoxygenated blood from regions superior to the heart, i.e., the head, neck, shoulder areas are collected through the superior vena cava and that from the parts inferior or lower to the heart like visceral organs, extremities, trunk, hip etc are brought through the inferior vena cava.

Both these venous systems (superior and inferior) fill the right atrium.

The right atrium then pumps the deoxygenated blood to the right ventricle via the tricuspid valve.

The right atrium is filled with blood during diastole.

solong [7]

Answer:

Multicellular

Eukaryotic

Heterotrophs

Explanation:

Both cells of fungi and animals are eukaryotic meaning they have  nucleus and organelles. They are multicellular organisms (meaning they are composed of many cells). Their cells are also heterotrophic meaning they depend on organic molecules for energy as opposed to plants that can make their food from abiotic factors. Fungi, however, digest their molecules extracellularly while animals do it intracellularly.

Predator and prey populations affect each other because if a predator of one prey kills that one animal than that animal dies and the prey decrease by one and when one predator dies from being killed or just naturally dying, then the predators decrease by one.
