Escherichia coli can generate energy under anaerobic growth conditions by fermentation, converting glucose to a mixture of ethanol and lactate. Under these conditions, the F1Fo ATP synthase is not required for ATP synthesis. Instead, the enzyme runs in reverse, hydrolyzing ATP and pumping protons out of the cell across the cytoplasmic membrane. This is a strategy that appears to waste ATP, so what is the physiological rationale for the ATP synthase running backwards when ATP is being made by fermentation? [Tip: you may need to do some research to answer this question, but also think about the mechanism of flagellar rotation].

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
