Answer:
300 oxygen atoms
Explanation:
Water = H2O ... this means 2 hydrogen atoms and one oxygen atom
2 hydrogen atoms = 1 oxygen atom
600 hydrogen atoms = ? oxygen atom
600 / 2 = 300
300 oxygen atom
E melts, it will cause a rise in sea level, which will affect and perhaps destroy ecosystems on coast lines. Changes in temperatures will also cause shifts in mating cycles, especially f
Unconventional or non criteria pollutants can include several toxic or non-toxic elements. Toxic chemicals, such as benzene, beryllium, PCBs, asbestos and vinyl chloride are man-made unconventional toxic pollutants that are regulated by the EPA. Other forms of unconventional pollution include noise, unpleasant odors and light pollution as well as aesthetic factors.

Explanation:
Environmental contamination reduces total testosterone oxido-reductase activity in females.- <u>True</u>
Enzymes are proteins which catalyze reactions by acting on substrates in order to speed up reactions- like the breakdown of large polysaccharides by amylase. Here, the enzyme testosterone oxi-reductase facilitates the of testosterone to the androgen DHT. Enzyme specificity is affected by pH, temperature and the presence of inhibitors.
In temperatures beyond its optimal range, these may undergo changes to its physical structure called denaturation; when denatured, enzymes lose their ability to bind specifically to their substrate -i.e. substrate binding specificity is lost. Testosterone would no longer be able to bind to the active site, and thus would not be converted.
