<span>The sugar arabinose in the agarose plate is needed to turn on the expression of the GFP (green flourescent protein) gene. The UV light is required to cause the GFP (green flourescent protein) protein within the bacteria to glow.</span>
The purine base adenine
The pentose sugar ribose

Three phosphates </span>
I would think its B but im not positive
The correct answer is: <span>oxygen is used up as algae is decomposed, reducing the amount available to other organisms. Algae require nutrients to grow, and it is well known that in many rivers, algal growth is limited by one particular nutrient, most often phosphates or nitrates. This means, as soon as there is a sizable input of nutrients into a river or lake, the algae population will grow exponentially. This dramatically changes the trophic status of a river or lake. However, the algal population will eventually exhaust the supply of nutrients, and the vast biomass of algae that grew over a short period of time will all die at the same time due to lack of nutrients. As you know, rotting organic matter uses up oxygen. This results in an anoxic aquatic environment that can kill all the other organisms living in that environment. </span>
