What is the result when a single cell reproduces by mitosis? two cells with genetic material identical to the parent cell
two cells with half the genetic material of the parent cell
four cells with half the genetic material of the parent cell
four cells with genetic material identical to the parent cell

The answer is two cells with genetic material identical to the parent cell.

Explanation: I am also studying this in class and we went over many instances where this question was brought up and the correct answer is four cells with genetic material identical to the parent cell because besides the fact that when you reproduce one cell you get two cells, (which makes logical sense from both a science and a math standpoint) you always have identical DNA to the parent cell and you never get half of it or else it would mess up the whole reproductive process.

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.
