In the previous question, you used the Hardy-Weinberg equation to determine the frequencies of the genotypes for HH, Hh, and hh, given gene frequencies of H = 0.2 and h = 0.8. These frequencies were: HH = 0.04, Hh = 0.32, hh = 0.64 Now, determine the expected numbers of each organism in the population (total size = 150): Number of HH = 6, 6.0 Number of Hh = 48, 48.0 Number of hh = 96, 96.0 In the next generation, this population has 14 HH members, 63 Hh, and 74 hh. Is the population in equilibrium? Answer either yes or no.

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.

Is there any species that went extinct in recent years due to natural causes (not caused by human interaction). if so, what caused it?

Monomers are the building blocks of larger molecules, called polymers. for example, proteins are composed of chains of amino acids that are linked together. cellulose is a polymer that makes up plant cell walls. cellulose is made from a chain of c6h10o5 molecules. which monomers are most likely used to produce cellulose? why?
