Place the parts of the circulatory system in the correct order to describe the flow of oxygenated and deoxygenated blood in the human body. aorta pulmonary veins left ventricle right atrium pulmonary arteries

The answer is; right atrium, pulmonary arteries, pulmonary veins, left ventricle, aorta

Deoxygenated blood from the tissues flows into the heart through the vena cava vein. The blood is pumped by the right ventricle to the lungs through the pulmonary artery. The blood gets oxygenated in the lungs and flows back to the heart through the pulmonary vein. The heart (left ventricle) then pumps the oxygenated blood to tissues through the aorta.  

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
