What is the function of the structure identified by the red arrow? (2 points) the image shows a bacterium with long tail-like projections streaming from it. the red arrow points to these projections.

the right answer must be fimbria.

in the field of bacteriology, we call fimbria, the small pilis that characterize many bacteria.

fimbria are proteinaceous appendages (consisting of filament-forming helical pilin subunits) found in many gram-negative bacteria that are thinner and shorter than flagellae.

they are not able to rotate and do not have complex basal bodies.

before it leaves the nucleus of a eukaryotic cell, mrna is altered in the following ways: - a cap is added to the 5' end of the mrna molecule; - a poly a tail is added to the 3' end; - introns are removed and exons are spliced together.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
