DOL 1. Populations can have variety, despite being made up of the same species. If a population has different expressed traits, this can be due to different inherited alleles. Genetic drift can cause a change in allele frequency in a population. What if you had to explain genetic drift to a friend who has not watched the video? Use the comics below in your narration of genetic drift. Refer to comic A, comic B, and comic C in your narrative. You can use the comics in any order you choose!

Salmonella typhimurium is a food-borne bacterial pathogen that can cause severe gastrointestinal disease. salmonella is often phagocytosed by macrophages that normally destroy bacterial pathogens, but this bacterium is somehow able to prevent the complete maturation of phagolysosomes. salmonella is able to tolerate the low ph of phagolysosomes, and in fact responds to the drop in ph by secreting toxins that interfere with other cellular responses. which of the following differences would you expect to contribute to the survival of a bacterium within an salmonella-containing phagosome, compared to a healthy phagolysosome? decreased activity of acid hydrolases increased activity of acid hydrolases decreased import of h+ ions increased import of h+ ions my guess is decreased activity of acid hydrolases but i'm not sure.
