The correct answer is '<span>Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.</span>' The additional nutrients in the water will result in an algal bloom. These algae will result in drastic oxygen fluctuation, from oxygen rich conditions during the day as algae photosynthesize, to anoxic conditions during the night when the algae respire. However, the algal bloom will eventually deplete the available nutrients, resulting in a vast algal die off. The decomposing algae result in anoxic conditions, and the effects are sometimes very obvious, with fish gasping for breath and dying.
The believe the answer is true but I'm not completely sure. <span />
The statement "<span>Fast riverine floods include flash floods from intense thunderstorms" is true. The two variables that contribute to flash flooding are rainfall intensity and duration. The greater the intensity and duration of the rainfall is, the greater is the tendency to have flash floods. It can roll boulders, uproot a tree, destroy communities. It can eve can reach 30 feet or more. It can also trigger mud slides which is very dangerous.</span>
16 neutrons are present in the most abundant isotope.
Explanation:
Phosphorus has 18 isotopes. The most common isotope has mass number (no. of protons 15+ no. of neutrons 16=) 31 .
