Answer:
There would be 500 daughter cells if 200 mouse cells went through the process of mitosis. (If that's what your asking)
Explanation:
During mitosis, the organism (which would be an asexual producer) doubles the amount of chromosomes and they divides the doubled number by two. So the organism will always end up with two daughter cells with the same number of chromosomes as itself. (That is the way with asexual producer's-their offspring is always an exact replica of the first). Now, if you take one mouse, it would end up with 2 daughter cells. If 250 mice reproduce, each with two daughter cells, then there would be 500 daughter cells in total, because you would multiply 2 by 250.
Circulatory -
Brings oxygen and nutrients where it is needed, removes toxic chemicals, maintains a stable body temperature
Digestive -
Food and nutrients are absorbed in the small intestine. These nutrients are necessary for other body systems to maintain homeostasis.
Excretory -
Removes all waste from the body, kidneys filter chemicals, liver filters toxins
I believe your answer is radioactive isotopes
Offspring of sexual reproduction are more likely to survive changes in the environment due to genetic variation and enabling better genes to be able to better the gene pool.
