Answer:
1. Aorta
2. Left atrium
3. Right ventricle
4. The pulmonary artery
5. Left ventricle.
Explanation:
The aorta is the main artery of the body that carries the oxygen-rich blood to all the body parts except the lungs from the left ventricle. It is divided into main coronary arteries or blood vessels.
The left atrium is one of the heart chambers, it is located in the upper part of the heart on the right side that receives the oxygenated blood from the lungs through the pulmonary vein.
The right ventricle is the chamber of the heart that pumps the deoxygenated blood to the pulmonary valve to MPA to the lungs to get oxygenated.
The pulmonary artery or the main PA (MPA) carries the oxygen-depleted blood from the right ventricle into the lungs, where blood becomes oxygenated.
The Left ventricle is the thickest muscle chamber of the heart responsible for the pumping oxygen-rich blood to the circulatory system and to the body through the aorta.
Answer:
C. True.
Explanation:
It should be understood that the the percentage of nitrogen is the highest in the atmosphere. This is because, it make up of more than 60% of the atmosphere. And it should be noted that the atmospheric nitrogen is inform that can not be used by the plant.
Therefore, there is a need for a certain group of bacteria which live in the root noodles of the plants to convert the unused form of the atmospheric nitrogen to a form that can be used by the plants.
DNA can be transferred naturally between species by breeding.
