Abacterial species that can grow when supplied an energy source and carbon source consisting of h2 and starch, respectively, and nitrate as a terminal electron acceptor, would correctly be considered: a. a hydrogenotroph b. a lithotroph c. anaerobic respiration d. two of a, b, c are correct e. a, b, and c are all correct

E. A, B, and C are all correct

Explanation:

The hydrogenotrophs are the organisms that can metabolize the molecular hydrogen into a source of energy. The lithotrophs are the organisms which use the inorganic substances such as carbon dioxide as their source of electron. The anaerobes are the organisms which use nitrate and sulphates rather than the molecular oxygen as a terminal electron acceptor.

i think it is dna, i'm not totally sure but i think it might be.

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.'
