You have been tracking a population of birds in the jungle and over several generations observed the following genotype frequencies for a given locus, b : 12% bb, 28% bb, and 60% bb. the climate changed abruptly and resulted in the death of all homozygous recessive birds. in the next generation, the recessive homozygotes died shortly after birth. what percentage of all newborn bird died ? (hint: you will need to recalculate the genotype frequencies after a portion of the population died and also use the product rule to calculate the proportion of matings that could lead to homozygous recessive individuals in the next generation.)

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.
