Answer: give new gene sequences to the host bacteria.
Explanation:
Bacteriophages are viruses that infect bacteria. Viruses are the most numerous organisms on earth and play functions in the biotic component of virtually every ecosystem. They are distinct biological entities and the main feature of this group is the dependence on specific hosts for reproduction, hence known as obligate intracellular parasites. In the lysogenic cycle, phage nucleic acid recombines with that of the bacteria forming a prophage and replicates in the host cell from one generation to another without cell lysis. By doing this, the bacteriophages give new gene sequences to the host bacteria, contributing to bacterial virulence.
Cells divide in two stages: Meiosis - haploid cell division [½ number of chromosomes], and Mitosis - diploid cell division [same number of chromosomes]. Their objective is to produce offspring, which means reproduce.
Glacial lakes are bodies of water that are influenced by the presence of glaciers. ... Glacial lakes are common features around the margins of glaciers and ice sheets, and often evolve from ice-contact lakes into ice-distal lakes as glaciers and ice sheets margins retreat and become spatially separated from the lake.
