Answer:

Carcinogenic

Explanation:

A carcinogenic substance is able to modify or damage the genome in a way which promotes the formation of cancerous cells. Cell cycle checkpoint proteins are very crucial for the progression of normal cell cycle. They check for any anomaly in their designated step and halt the process if it is detected. Repair mechanism is activated and cell cycle does not progress till the damage has been repaired.

Here, the pollutant alters the structure of these proteins such that they lose their function. They are not be able to stop cell cycle from progressing even if there is some damage in the genome. The cell divides and gives rise to more damaged cells. Eventually these cells lose their normal function and just keep dividing due to which their division rate becomes double of the normal rate. It can ultimately give rise to cancer which is why the chemical is carcinogenic.

mars1129 [50]

Answer and explanation;

Nucleus; houses a cell's DNA and its processes include protein, replication and packaging for cell division. It is also the site for transcription.

Cytosol; coordinates a responsible to the environment, metabolism and motor proteins.

Endomembrane system; includes the nuclear envelope (surrounds nucleus), rough and smooth ER, golgi body, lysosomes?vacuoles, peroxisome and plasma membrane.

Semiautonomous organelles; mitochondria (animals) and chloroplast (plants) which provide energy for the cell.
