Answer:

The correct answer is -

Top box (green area) - moderate rain,

Middle box (sky blue area) - light rain, and

Bottom box (red area) - heavy rain.

Explanation:

As per the map and the scale presented on the map that indicates the rainfall in inches. The green area indicates that the rain fall in this area is one inch which is moderate as the the sky blue rainfall measurement is .5 inches which is half. However, the red area is the highest rainfall area in comparison to both of these which is about four inches.

On the basis of these it we can label all three boxes as per their rainfall amount that is,

Top box (green area) - moderate rain,

Middle box (sky blue area) - light rain, and

Bottom box (red area) - heavy rain.

Lynna [10]

Answer:

Explanation:

1- the purpose of blood flow-circulatory system- is to convey  Oxygenated blood, oxygen bonded with haemoglobin in the RBC with Nutrients - and distributed these through the arteries  and capillaries  away from the heart,  to reach the cells and tissues, and transported the wastes of theses cells and tissues , with C02 through the veins back to the heart and the kidney.

2. During diastole,deoxygented blood from the inferior and superior vena cavae entering the R.atrium, passes through the tricuspid valve into the Right Ventricle. Simultaneously, oxygenated blood returning through the pulmonary veins enters the left Atrium,emptied  through the bicuspid valve into the Left.Ventricle.

During systole, the two ventricles contracts. The Right ventricle contracts, the pressure of the blood forces  the tricuspid valve to close,and therefore de -oxygenated blood pushes the pulmonary  valves to open and blood passes through the pulmonary artery to reach the lungs where exchanges of oxygen with carbon dioxide occurs.The blood is now oxygenated and returns to the left atrium via pulmonary veins.

Simultaneously, the left ventricle contracts,the oxygenated blood it contains forced the bicuspid valve to close so that blood is  forced through the aortic valve  to empty into the aorta into  the systemic circulation,branches of the carotid artery supplies the heart from the aorta.

The Whole cycle continues.
