8.1 K is the amount if bonds that nitrogen have
True this is so true alcohaul impacts and harms your body but not only physically also mentally.
In region C the enzyme is saturated with substrate.
The fee of reaction whilst the enzyme is saturated with the substrate is the maximum charge of the response, Vmax. the relationship between the price of response and awareness of substrate relies upon the affinity of the enzyme for its substrate.
whilst all lively sites are occupied, the enzyme is saturated. At this saturation point, adding extra substrate makes no difference to the response rate.

Answer: He could add a base to the pool to neutralize the acid.
Explanation:
Chlorine is used to disinfect the pools as it produces hypochlorous acid in water. This hypochlorous acid is unstable and gives hydrochloric acid and nascent oxygen which is used to disinfect.

The excess acid is neutralized by adding base which produces salt and water and thus decrease the acidity.

Adding more acid would increase the acidity further.
Out of the three you gave ecosystem is what I would call the most broad. An ecosystem includes living AND non-living things in an area
Community is all the LIVING things in an area (plants are included and I think bacteria is too, but I'm not sure)
Population is pretty narrow it just looks at specific species in one area. Population of mosquitoes doesn't include butterflies, if only looks at mosquitoes
Hope this helped!
