ANSWER:
The effects of increasing or decreasing the nutrient levels in an aquatic food webs is described in the explanation.
Explanation:
If the nutrient levels in an aquatic food web increase moderately then it will result in increased production of the primary producers and the consumers.
But if the nutrient levels are increased excessively, like in eutrophication, then the increased level of nutrients will result in overproduction of the consumers like fishes, etc. Hence, there will be a scarcity of resources like oxygen in the water to support them and this will lead to a decline in biodiversity of the aquatic food web.
If the nutrient levels are decreased, then there will be competition for resources among the species which will ultimately lead to the decline of some species from the aquatic food web.
The organism should be re-incubating to permit it to have additional opportunity to create finished results that might be acidic. It may be the case that there isn't sufficient finished result to change the shade of the Methyl Red yet.Some microbiologists prescribe re-brooding life forms delivering methyl red-negative outcomes for an extra 2 to 3 days to build test sensitivity.
Answer:
They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick.

Answer:
Restriction enzymes (endonucleases) are used to cut the DNA into fragements.
Explanation
Restriction enzymes are obatained from bacteria where they are utilized by bacteria for protection against viruses. Restriction enzymes are used in biotechnology research. There are several restriction enzymes and each cut the DNA at specific site known as recognition site which is usually 4-8 neucleotide long. They produce sticky ends (cutting the both DNA strand on different site) and blunt ends (cutting the both DNA strand on same site) on DNA fragments.
