Oxygen from the respiratory system is delivered by the circulatory system.
<h3>What is the relationship between respiratory and circulatory system?</h3>
The respiratory system is responsible for delivering oxygen to the circulatory system that is made up of blood vessels which carry blood to the heart and then all cells of our body. Arteries carry blood that is loaded with oxygen from the heart to all cells whereas veins carry deoxygenated blood back to the heart and then to the lungs for disposing carbondioxide. The circulatory system carries oxygen and nutrients to the cells, and removes waste products such as carbon dioxide.
So we can conclude that Oxygen from the respiratory system is delivered by the circulatory system.

When the ocean waters in the Pacific ocean warm up and the currents begin to move eastwards towards the Western South American coast, then an El Nino is declared. This phenomenon also shifts tropical storms eastwards due to the exchange of heat between the hydrosphere and the atmosphere. El Nino occurs in a cycle every three to five years.
<span>Molecular clock is a scale which uses a technique whereby evolutionary time for different life forms is deduced from the mutation rate of biomolecules. Biomolecular data used for calculations in order to come up with the prehistoric time scale normally uses nucleotide sequences for DNA or amino acid sequences for proteins.
Hence, in order to develop a molecular clock, one would need: a sequence of molecules, the rate at which changes occur in a type of molecule and how much total change has occurred in a type of molecule from different species.</span>
