GIVING OUT BRAINLIEST TO THE FIRST CORRECT QUESTION ANSWERED!! Read the passage. Then explain why the circulatory system of a grasshopper does not need to carry gases to and from the grasshopper's cells.

The diagram shows part of a grasshopper's respiratory system. Air passes into and out of openings in its sides. These openings are connected to tubes and air sacs that fill with air. The air tubes branch into tiny tubes that spread out and are found to close to all cells. So, unlike other animals, the grasshopper does not exchange gases using its circulatory system.

ans.

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.'

well, i believe that the answer is 2. : 3

yes, because even though a theory has a  lot of evidence to support it, it is not always true
