Select the pair of organs, that contains a large number of mitochondria:
Correct answer: E. Heart and Muscle
- A. Stomach and Liver
- B. Muscle and Stomach
- C. Heart and Liver
- D. Liver and Muscle
- E. Heart and Muscle
Explanation
The correct answer is Heart and Muscle. Both the heart and muscle tissues require a significant amount of energy due to their continuous and vigorous activities. The heart, in particular, is constantly pumping blood throughout the body, necessitating a high number of mitochondria for energy production. Muscle cells also need a lot of energy for movement and thus have many mitochondria. The other options, such as the liver, although rich in mitochondria, do not match the heart's concentration. The stomach does not have as high energy demands as these organs.
