Answer:
the bacteria increase in number and use up the dissolved oxygen in the water. When the dissolved oxygen content decreases, many fish and aquatic insects cannot survive. This results in a dead area. Algal blooms may also be of concern as some species of algae produce neurotoxins.Explanation:
Answer:
Some bacteria like <em><u>rhizobium</u></em> and <u><em>blue green algae</em></u> are able to fix nitrogen gas from the atmosphere to enrich the soil with nitrogen compounds and increase its fertility.

Answer:
1. 17 protons / 10 neutrons
2. Scandium
3. Negative
Explanation:
1. The bottom number is the same as the atomic number on top of the abbreviation. To find the # of neutrons, subtract the mass number with the number of protons
2. The bottom number (21) is the number of protons AND the atomic number (the a.n & # of pro. are always going to be the same)
3. Always think about this: if you add electrons, you take away charge - if you take away electrons, you add charge
*Idek if these were the correct correct answers but I tried my best*
The electron configuration for N is 1s^2 2s^2 2p^3, or it could be [He]2s^2 2p^3 but you don’t have the diagram out so I can’t say the definite answer
