Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each cell?

2 (if you are just talking about Mitosis)

Explanation:

In Mitosis (the reproduction of body cells) there are two diploid (and identical) daughter cells

In Meiosis (the reproduction of gametes) there are four haploid (but non-identical) gametes (or reproductive cells)

I am pretty sure that you are talking about Mitosis but I wanted to add in Meiosis just for kicks.

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.
