It is estimated that 99 percent of all production problems in crawfish ponds are related to poor water quality. Dissolved oxygen (D.O.) is the most serious problem, but pH, total hardness, total alkalinity, ammonia, nitrite, hydrogen sulfide, and iron can also affect crawfish production.

dna is soluble in water but not ethanol. what does this fact have to do with out method of extraction? explain what happened when the ethanol came in contact with the strawberry extract.his means you see it as a solid. When DNA comes into contact with ethanol it precipitates out of solution so you can see it forming in the clear layer above the strawberry solution. It is seen as a thread like substance, often has tiny bubbles associated with each thread when you do this extraction. Hope this helps.
