E) When two bacteria are linked during conjugation, the donor cell passes DNA to the recipient cell which causes genetic recombination.
Explanation:

Answer:
in eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus. All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm.
Explanation:
It is problematic due to antibiotic-resistance that would
occur. This extensive use and abuse of antibiotics result in the emergence of resistant
strains of bacteria. Some types of

resistance to most or all of the available treatments, and there are very few
promising options in the market.
