Which type of substance is an environmental contaminant that causes harm to living organisms?

answer; i believe that the correct answer is; ///bodies of water store heat during the day and release it at night;

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
