First, a petri dish (a shallow, circular, transparent dish with a flat lid) is partially filled with nutrient-enriched agar (a gelatinous material). The nutrients encourage growth of specific bacterial species. The agar is poured as liquid but then typically solidifies to a soft consistency. Once the agar is set, a "lawn" of bacteria is spread such that a thin layer covers the top of the agar. Antibiotics are then applied to the lawn in a small dose, often through small, saturated paper disks. The dish is typically incubated for 24-48 hours and then observed for susceptibility. If the antibiotic is effective, it will kill the bacteria and leave a clear area called the "zone of inhibition" due to inhibited bacterial growth. The area starts at the source of the antibiotic and radiates outward. Scientists measure the diameter of the zone and then compare it to an established "cutoff value" for a zone specific to antibiotic/organism combinations. A large zone of inhibition in comparison to the standard indicates susceptibility while a small or no zone indicates resistance. Consider the following image, and answer the questions that follow: What can you conclude about the susceptibility of the bacteria to the antibiotics?

Peter and Rosemary Grant have been conducting observational research studies on finch species on Galápagos Island Daphne Major for over 40 years. The medium ground finch has a relatively small beak and a diet that consists primarily of small seeds. Large-beaked finches are able to eat larger seeds in addition to small ones. These two species successfully co-existed on the island for over 20 years, but two years of severe drought in 2003 and 2004 lead to intense competition between them because food supplies were destroyed in the drought. Numerous birds in both populations died from starvation. Interestingly, the Grants noticed that the smaller-beaked finches did not face the same degree of competitive pressure, because they could more easily eat the smaller seeds that were not being eaten by the larger finches. Only a short time later (2004-2005), the Grants observed that new populations of finches had more birds with smaller beaks than larger ones. As well, finches tended to seek out larger seeds half as often as in preceding years. The Grants' data suggest that ________.

Dinоsаurs (аside frоm the lineаge that prоduced birds) were extinct by the end of the ________.
