For the diffusion and osmosis lab, you gathered data based on changes in the weight of model cells. to design your experiment, you made educated assumptions about what would pass through the dialysis tubing membrane, and what would not? using knowledge you gained during the macromolecules lab, give examples of how you could tested these assumptions in relation to movement of starch, sugar and proteins. these examples do not need to relate to your group's experiment.

Which of the following is an example of this type of co-evolution

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.

What kind of bond is created by the attraction between atomic particles of opposite charge? ionic bond hydrogen bond covalent bond nuclear bond
