Two chromatids attached by a centromere are referred to as sister chromatids. How many total chromatids would a human cell contain after the DNA has been replicated?

92 Chromatids

Explanation: A chromatid is one of the two strands that form when a chromosome duplicates itself during cell division. Before DNA replication, the somatic cell has 46 chromosomes. Subsequently after the DNA replication, each chromosome will possess two physically attached sister chromatids, the chromosomes will condense to form compact structures (though it'll still be made of two chromatids). Thus, after replication, there would be 92 chromatids.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
