A scientist designed and conducted an experiment to test a hypothesis, and then formed a conclusion from her results. Next, she collected and analyzed more data and formed another conclusion. Which statement best justifies the fact that she skipped the hypothesis and experimental design steps of the scientific method? The scientist must have realized that she performed one of the steps incorrectly. The scientist was unhappy with the first data set and started the experiment over. The scientist was repeating the experiment to improve the validity of her data. The scientist was planning to form a hypothesis after completing the experiment.

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.
