Which image is a correctly labeled prokaryotic cell?

The correct answer will be-the pic with long flagellum and small pili surrounding the bacteria

Explanation:

A bacteria is considered a prokaryote on the basis of its structure. The bacterial cell contains loosely arranged DNA freely floating in the cytosol instead of a nucleus.  

The surface of the bacteria contains the plasma membrane extension called pili which helps attachment to the substratum and the long flagellum sued for locomotion. The ribosomes are the small circular units for translation which freely floats in the cytosol.

These structures are correctly labelled in the attached figure and thus, the attached figure is the correct answer

"d.) carbon dioxide and hydrogen sulfide"

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.
