You are studying cellular respiration in cultured cells. By mistake you add a bacterium that is known to stop the process of cellular respiration. To understand the mechanism, you notice the buildup of pyruvate and the presence of H+ ions outside of the mitochondria and the cells die due to a severe reduction of ATP inside the cell. What is the most likely effect the bacteria are having in these cells to cause the observed results?

Interestingly, Myrmecia pilosula was originally described as a single species; but it actually consists of several distinct, closely related species with females having diploid chromosome numbers of 18, 20, 32, 48, 60, 62, and 64. Yet all the ants look pretty much alike! Assume that a cross occurs between a female of Myrmecia species (A) with 32 chromosomes and a male Myrmecia species (B) with 9 chromosomes (remember, males are haploid and transmit all their chromosomes to each sperm cell). How many chromosomes would be expected in the somatic (non-gametic) cells of the hybrid females?
