36) how do we describe transformation in bacteria? a) the creation of a new strand of dna from a dna template molecule b) the creation of a strand of rna from a dna molecule c) the infection of cells by a phage dna molecule d) assimilation of external dna into a cell

The correct answer is D) assimilation of external DNA into a cell

Explanation:

A bacteria is called transformed when it consist a genetic material that is not it's own but taken from outside the cell. So transformation of bacterial cell defines the uptake of foreign DNA by bacterial cell from its surrounding.

This transformation in bacteria is necessary because it provides bacteria some new and extra genes that help it to survive in the adverse and changing environment.  

Transformation can result in getting the antibiotic-resistant gene to the bacteria which protect the bacteria from antibiotics during infection when antibiotic is used against it.

So the right answer is D) assimilation of external DNA into a cell.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
