The microorganisms that make up the normal human flora are important for which of the following?

The correct answer to this question would be:

The microorganisms that make up the normal human flora are important for “preventing the colonization and multiplication of pathogens”.

The human flora or human microbiota is the totality of microorganisms which resides on or within our body. The normal flora of humans is composed of a few eukaryotic fungi and protists, but bacteria are the most abundant and obvious microbial components of the normal flora. The microorganisms of the normal flora help the body fights against the pathogens by challenging for microenvironments more effectively than such pathogens or by supplying nutrients the body can use.

it is a learned trait

explanation:

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
