an atom is the smallest particle of an element that still has the same chemical properties.
If you smoke for many years, these chemicals pass into your bloodstream and are filtered by the kidneys into your urine. The bladder is repeatedly exposed to these harmful chemicals, as it acts as a store for urine.
Smoking irritates the bladder and can make IC symptoms worse. Incontinence (leaking urine) and Overactive Bladder (OAB), impact more than 33 million men and women. Smoking bothers the bladder and can cause frequent urination. It can also cause coughing spasms that can lead to urine leakage.
This can cause changes to the cells of the bladder lining, which may lead to bladder cancer.

Answer:
Doubles the amount of DNA and reduces the chromosome number from 2N to N.
Explanation:
Meiosis is a cell division in which one cell divides into 2 cells in the first meiotic division and then these two cells divide into two more cells so overall 4 cells are produced from one cell. This division occurs in gamete cells.
First, the amount of DNA gets double by converting the single-stranded DNA into double-stranded DNA. Then the homologous chromosomes get separated into two different cells in the first meiotic division and till now the chromosome number is 2N.
After the second meiotic division, each sister chromatids of a chromosome gets separated into separate cells and the chromosome number in daughter cells becomes 1 N. So the major role of meiosis is to double the DNA mount and reduce the chromosome number by half in all daughter cells.
