Answer:
The correct answer is A, as the statement is true. All blood returns to the heart by way of either the superior vena cava or the inferior vena cava.
Explanation:
The heart pumps blood to all parts of the body. Blood supplies oxygen and nutrients to the entire body and removes carbon dioxide and residual elements. As blood travels through the body, oxygen is consumed and blood becomes deoxygenated.
Deoxygenated blood returns from the rest of the body to the heart through the superior vena cava and the inferior vena cava, the two main veins that carry the blood back to the heart.
Answer:
For example, an atom with 6 of 8 electrons in its outer shell will try to gain 2 electrons so its outer shell is full. Ionic bonding occurs when one element donates an electron (or electrons) to another so that both elements will have a full outer shell. As the attractions bring the atoms together, electrons from each atom are attracted to the nucleus of both atoms, which “share” the electrons. The sharing of electrons between atoms is called a covalent bond, which holds the atoms together as a molecule.
