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.

Answer:
Gradually released into the atmosphere by photosynthetic microbes, it formed two important gases new to fledgling Earth: breathable oxygen gas, or O2, and ozone, or O3. Together, the buildup of these gases enabled life to emerge onto land and evolve into the rich diversity of life-forms that inhabit Earth today.
Scientific method is a continuous process. This process starts with the observation of a certain phenomenon. Based on what is observed, a hypothesis is develop to describe this phenomenon. This hypothesis is then tested by experiments where the results of these experiments either confirm or contradict the developed hypothesis.
If the hypothesis is contradicted by the results of the experiment, then another hypothesis is developed and tested for either confirmation or contradiction.
Based on this, any question that cannot be tested and studied experimentally cannot be solved using scientific methods.
C would most likely be the correct answer: think of Darwin's finches and their varying bill lengths. This is all due to what they can eat. The same would apply to the Hummingbirds in this diagram: there is an abundance of short and long tubed flowers, thus causing disruptive selection in the medium sized bills (as they wouldn't fit properly).
