Answer:
An organism would need a 4 chambered heart.
Explanation:
The heart consists of 4 chambers in which blood flows freely. Right atrium, left atrium, left ventricle and right ventricle.
The pulmonary arteries carry de-oxygenated blood to the lungs from where CO2 is released and O2 is picked up during the process of respiration. The pulmonary vein then takes the oxygenated blood to the left atrium of the heart and then to the left ventricle of the heart.
Mitochrondria of the eukaryotic cells.
<span>As many researchers hypothesize that the old single-celled organism or the origin of the complex-celled organisms came from the endosymbiosis of the mitochrondrion organism and the prokaryotic cell. It has been said that mitochondria was an independent organism which then to have been evovled itself after planting itself inside a prokaryotic cell which aided cellular respiration and production of ATP (Adenosine Triphosphate). This then aided the prokaryotic cell to be more sophisticated and caused another change from having without a true nucleus to a eukaryotic cell with a nucleus and embedded DNA. <span>
