DDT and other pesticides used over 50 years ago are still affecting the
environment today. Scientists have found these substances in recent
glacier runoff. Glacier runoff occurs during the summer, when precipitation
that has fallen on glaciers during the winter is released. Ice layers from
existing glaciers have been analyzed. The results of this analysis show that
the concentrations of DDT and other pesticides were highest about 10
years after the use of these substances was banned. This information
shows that *

C. Precipitation helps to break down pesticides.

prophase is the first step in mitosis and will show one huge circle (nucleus) and centrioles - nothing is being done to it. metaphase is the third step and where the chromatids meet in the middle and the centrioles are at opposite ends. anaphase is the fourth step and where the chromatids start to split/separate. telophase is the second to last step where the chromatids start to split along with the centrioles, it looks like there is getting ready to be two different cells. if you follow this, then it should you to answer what it looks like. have a great day and i hope i you! if i did not answer your question or you are confused, let me know and i will you as much as i can.
