Number of cells that are destroyed in adults by apoptosis are ________ ?
Correct answer: B. 50 to 70 billion cells
- A. 20 to 35 billion cells
- B. 50 to 70 billion cells
- C. 10 to 20 billion cells
- D. 15 to 25 billion cells
Explanation
Apoptosis continuously removes approximately 50 to 70 billion cells per day in an adult, balancing the production of new cells and maintaining tissue size. Students may choose 20 to 35 billion by underestimating the large amount of normal cell turnover in the body.
