The accurate response is "Hfr strains integrate the F plasmid into their chromosome".

This relates to the process of horizontal gene transfer in bacteria, which involves the movement of an "F plasmid" during bacterial conjugation. Bacteria possessing the F plasmid are called "F+ strains". The primary distinction between Hfr strains and F+ strains lies in that the former has the F plasmid integrated into their chromosome, whereas the latter retains the F plasmid freely in the cytoplasm without integration into their genetic material.

Which statement best describes the breakdown of food in the digestive system?
Tresset [2298]
The second option is correct. Carbohydrate digestion initiates in the mouth, while protein digestion begins in the stomach. Specifically, carbohydrate breakdown starts in the mouth through mechanical chewing and the enzyme salivary amylase present in saliva. In contrast, protein digestion takes place in the stomach where enzymes such as pepsin (from the stomach), trypsin, and chymotrypsin (from the pancreas) act to decompose the food proteins into polypeptides and progressively into amino acids.
