The answer is A, storing urine until it is eliminated.
The bladder stores urine, allowing urination to be infrequent and controlled. The bladder is lined by layers of muscle tissue that stretch to hold urine. The normal capacity of the bladder is 400-600 mL. During urination, the bladder muscles squeeze, and two sphincters (valves) open to allow urine to flow out.
Answer:
Chromosomes at the conclusion of Meiosis I - 
Double-helical molecules of DNA at the conclusion of Meiosis I - same as that of parent cells
Explanation:
Given
Number of chromosomes in the diploid cells of Aliens from the planet Zorg 
In the Meiosis I cell division , a cell divides to produce two diploid cells with exactly the same amount of DNA as that of original parent cell.
However, the number of chromosomes is reduced to by half at the end of meiosis I
After Meiosis II, four haploid cells are produces with half the amount of DNA as that of original parent cell
Thus,
Chromosomes at the conclusion of Meiosis I - 
Double-helical molecules of DNA at the conclusion of Meiosis I - same as that of parent cells
The answer is 2 because they are renewable which means replaceable
