Nitrates are made by converting ammonia (NH3) to nitrite (NO2-) and then to nitrate (NO3-). What do you predict the O2 levels in
AlexFokin [52]

Answer:

Low - The generation of nitrates (NO 3-) requires oxygen, so the oxygen levels will be low

Explanation:

Nitrates are formed when the ammonia react with oxygen present in water. The oxygen which react with ammonia is not the oxygen of water molecule, it is the dissolved oxygen. This oxygen is used by aquatic animals for breathing. If nitrates are formed so the concentration of dissolved oxygen will be lowered which causes suffocation and bad impact on marine organisms and the whole ecosystem will be disturbed.

You can measure and describe climate by walking out the door and describing current atmospheric conditions. true or False
Xelga [282]

Answer:

The answer is "False."

Explanation:

The sentence above is stating that you can<u> "measure"</u> and describe climate by "walking out the door and describing current atmospheric conditions." This is "false" because climate cannot be measured by qualitative descriptions or subjectively. Measuring it entails quantity which is objective in nature. An example of this is by using "thermometers" or "rain gauges."

Although you can describe the atmospheric condition or the climate just by walking out the door,<em> you can never measure it.</em>

Thus, this explains the answer.
