Answer from: julk89

Answer;

An increase in the total biomass of consumers in the world

Explanation;Carbon fixation is the process through which carbon dioxide is removed from the air and incorporated into an organic molecule.Carbon fixation occurs during the light independent reaction of photosynthesis and is the first step in the C3 or Calvin Cycle. The Calvin cycle uses the energy from short-lived electronically excited carriers to convert carbon dioxide and water into organic compounds that can be used by the organism.

Answer from: astigall6360

a decrease in the total biomass of consumers in the world

Explanation:

A decrease in carbon fixation would likely increase the amount of carbon dioxide in the air and decrease the amount of oxygen. This would change how much respiration and photosynthesis could take place, resulting in:

a decrease in the total biomass of consumers in the world,

an increase in the total biomass of producers in the world, and

a decrease in the size of insects and arthropods, since their ability to move oxygen from the air into and through their bodies is limited.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'

Taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? view available hint(s)taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? the enzyme will not work on human dna.nothing should be altered.the ph should be decreased.the temperature should be raised.
