If a lake became too acidic, which of the following describes the best way that scientists could determine how to make the lake more
neutral?
A. Dump a large quantity of a base, such as sodium hydroxide, into the lake.
B. Use samples of the lake water as models for testing the results of adding various chemicals.
C. Siphon off the acidic portions of the lake and leave the rest of the water alone.
D. Double the amount of water in the lake, so the acidity will be diluted.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

answer; i believe that the correct answer to this statement is (exoticism); //

exoticism was a trend where musicians created music based on a far off foreign
