In some third world countries "cyanide fishing" for aquarium trade is allowed. cyanide fishing uses the cyanide to "stun" fish and make them easy to catch. but the cyanide combined with handling stress has led to a mortality rate in the captured fish somewhere between 60% and 80%. knowing this, how might this method impact the environment? cyanide is a safe chemical, so there will not be any effect on the environment.
b) increase cyanide levels in the water will increase the biodiversity in that area.
c) since so many fish are being caught, there is more room for predators to flourish.
d) it could lead to overfishing, since more fish have to be caught due to the high mortality rate.

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
