<span>The greatest concentration of nitrogen on the Earth is found in its atmosphere. The atmosphere is approximately 78 percent nitrogen. and second one bacteria</span>
<span>Density = mass/volume = 200g/2cm^3 = 100 g/cm^3
Density of water = 1g/cm^3
Specific Gravity is the ratio of the Density of the object to the Density of water so the Specific Gravity is 100
Piece of metal has a </span>Specific Gravity if 100

Answer:
The circulatory system or vascular system is an organ system that helps in the transport of the blood from and to the heart. The blood transport also takes oxygen, nutrients, hormones, and other components from the heart to the various part of the brain with the help of the arteries and carry waste such as carbon dioxide to the heart in veins.
The oxygenated blood enters in the left atrium and moves to the left ventricle to the aorta and starts its journey to the body whereas deoxygenated blood enters in the right upper chamber or right atrium of the heart and pump to the right lower chamber and to the lungs to carry the oxygen again. This process is a continuous process.
