Answer:
D. Normal cells have a large amount of cytoplasm, while cancer cells have a small amount of cytoplasm.
Explanation:
The cells that repeatedly undergo cell division have higher nuclear to cytoplasm ratio. Cancer cells undergo repeated uncontrolled cell division. They have a higher nuclear to cytoplasm ratio and maintain a small amount of cytoplasm. The larger nucleus of cancer cells has coarse hyperchromatin.
On the other hand, normal cells have a large amount of cytoplasm as compared to the cancer cells. They have fine chromatin and exhibit controlled cell division.
The answer is PROSTATIC urethra. It is the proximal portion
of the urethra which begins from the urinary bladder and passes
through prostate gland. The urethra is divided into a long and short

Scientists developed the time scale by studying rock layers and fossils world wide.
Radioactive dating helped determine the absolute divisions in the time scale. so mass extinction help because there is more to study
