<span>Bacterial genome is prone to mutational changes due to its simple nature and less efficient DNA repair mechanisms compared to humans, thus it has more chances of obtaining new genetic traits.</span>
I believe the answer is TRUE.
Unoxygenated blood from veins enters the right atrium then it goes down to the right ventricle then out through the pulmonary artery to the lungs where it becomes oxygenated blood which then enters the heart through the pulmonary veins and it goes to the left atrium and then is pumped down to the left ventricle and out through the aorta to the arteries where it travels to different organs and becomes deoxygenated and then the cycle repeats itself.
The answer is B) hope this helped you
