During mitosis ,replicated chromosomes are positioned near the middle of the cytoplasm, then they are segregated so that each daughter cell receives a copy of the original dna true false

True

Explanation:

During mitosis, replicated chromosomes are aligned in the equitorial plate of the cell i.e. near the middle of the cell. It happens in metaphase of mitosis. As soon as they align in the middle of the cell, anaphase starts in which they begin to separate from each other due to the formation of spindle fibres which attach themselves to the kinetochore protein of each sister chromatid. After attachment, the spindle fibres start shortening as a result of which the sister chromatids get segregated to reach the opposite poles. After the completion of telophase and cytokinesis, segregated sister chromatids form the genetic material of each daughter cell.

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.

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
