A cell come a certain organism has 64 individual, or 32 pairs, of chromosomes. Which of these can you draw?
Dmitriy789 [7]

Answer:

B. The cell cannot be a human

Explanation:

Humans have 23 pairs of chromosomes, or 46 individual chromosomes. Mutations in humans usually cause there to be a single extra chromosome, or a single missing chromosome. A mutation would not cause there to be 64. So, A cannot be true. Prokaryotic cells usually have one chromosome, not 64, so C cannot be true. D cannot be assumed as you cannot tell if there is uncontrolled cell growth. Therefore, the answer would be B.
