Gibberellins are hormones produced in the root tips of plants. The plant uses these hormones
to stimulate the growth of shoots.
How are gibberellins able to affect other parts of the plant?
F Gibberellins are absorbed through the stomata and attach to chloroplasts.
G Gibberellins are transported through vascular tissues to other parts of the plant.
H Gibberellins become concentrated within the tissues of the plant during mitosis.
J Gibberellins become modified once they infect healthy cells and are later released to infect
other cells.

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.
