Answer;
D. polynucleotide
Explanation;
DNA is found in nearly all living cells. However, its exact location within a cell depends on whether that cell possesses a special membrane-bound organelle called a nucleus.
Although each organism's DNA is unique, all DNA is composed of the same nitrogen-based molecules. It is simply the order in which these smaller molecules are arranged that differs among individuals. In turn, this pattern of arrangement ultimately determines each organism's unique characteristics.
At the most basic level, all DNA is composed of a series of smaller molecules called nucleotides.
I know 1 of them is Nature
Generally speaking, enzymes (which amylase happens to be) do not undergo any permanent structural change while carrying out their function. Some do exhibit transient conformational change during a reaction, but upon completion regain their original form.
So your initial assumption is correct: once amylase has finished catalyzing the breakdown of starch into less complex sugar molecules, it moves on and repeats the process over and over.
Answer:
Increased levels of phosphate are beneficial to phytoplankton and aquatic plants. In the short-run, this means increased micronutrients for herbivorous and omnivorous fish.
The phosphate, however, reacts with the water to reduce the oxygen levels obtainable in the water. Without oxygen, the fishes die off.
It is not unusual to find that with increased phosphate in water, healthy fishes begin to die off without any other plausible explanation.
The solution is to clean the water or treat it with solutions that impact positively whilst reducing the phosphate levels.
