It would be d because a cell is least complex and organ system is most complex
Some organisms may be very closely related, even though a minor genetic change caused a major morphological difference to make them look quite different. For example, chimpanzees and humans, the skulls of which are shown in Figure 12.2. 2 are very similar genetically, sharing 99 percent1 of their genes. Hope this helps! Mark brainly please!
Answer:
The mechanism by which organisms use oxygen to break down food molecules in order to obtain chemical energy for cell functions is known as cellular respiration. In the absence of oxygen, cells can generate energy by fermenting food, a mechanism known as anaerobic respiration.
