The correct answer will be A;
A) The number of protons in the nucleus does not equal the number of neutrons.
A=mass number:
Z=atomic number (= number of protons)
N=number of neutrons:
A=Z+N
If the number of protons in the nucleus is equal the number of neutrons , we would have an even mass number; because Z=N=x; then A=x+x=2x (this is always an even number) but 23 is an odd number, therefore the number of protons in the nucleus does not equal the number of neutrons.
Answer:
The blood goes through an oxygenation process that is carried out by the blood vessels, the heart and the lungs, so if any of these structures is affected the entire circulation system will be altered. The circulatory system is made up of two circulatory systems: the pulmonary that provides oxygen to the blood and the systemic that carries it to all the tissues of the body
Explanation:
The veins transport the deoxygenated blood to the heart pumps this blood back to the lungs, where it absorbs more oxygen. This oxygenated blood returns to the left side of the heart, which pumps it to the rest of the body through the arteries. Pulmonary circulation is a process in which the lungs, heart, veins and pulmonary arteries intervene, with the aim of oxygenate the blood.This system begins in the left ventricle of the heart, since this is the chamber through which it exits deoxygenated blood that has already fulfilled its function in all tissues of the body, to later reach the lungs through the blood vessels in the region.Systemic circulation is a long process that involves the chambers of the heart and blood vessels throughout the body, with the aim of carrying oxygenated blood to the tissues that are further away and thus allow all to function in the best way
There are omnivores, carnivores, herbivores, and decomposes. Omnivores eat both plants and animals, carnivores eat animals, herbivores eat plants, and decomposers feed on dead material.
