Textbook Question
Chapter 49, Problem 15PIAT
QUANTITATIVE Conservation biologists are scrambling to put measures in place to contain the spread of lionfish. For example, Stephanie Green and colleagues measured how quickly the number of native fish would recover if varying numbers of lionfish were removed from reefs in the Bahamas. They randomly assigned 24 reefs to one of four groups and plotted the proportional change in the number native fish at six-month intervals after different amounts of lionfish (0%, 25%, 75%, or 95%) were removed. (In the graph that follows, values above 1 on the y-axis represent amounts that exceed those at the start of the study in 2009, while values below 1 indicate declines.) Compare the percentage of native fish observed in June 2011 after 25 percent versus 95 percent of lionfish were removed. What is the take-home message?

- engineered constructs that consist of hollow fibers are acting as synthetic capillaries, around which cells have been loaded. The cellular space around a single fiber can be modeled as if it were a Krogh tissue cylinder. Each fiber has an outside “capillary” radius of 100 µm and the “tissue” radius can be taken as 200 µm. The following values apply to the device:R0 = 20 µM/secaO2 = 1.35 µM/mmHgDO2,T = 1.67 x 10-5 cm2/secPO2,m = 4 x 10-3 cm/secInstead of blood inside the fibers, the oxygen transport and tissue consumption are being investigated by usingan aqueous solution saturated with pure oxygen. As a result, there is no mass transfer resistance in the synthetic“capillary”, only that due to the membrane itself. Rather than accounting for pO2 variations along the length ofthe fiber, use an average value in the “capillary” of 130 mmHg.Is the tissue fully oxygenated?arrow_forwardMolecular Biology Please help with question. thank you You are studying the expression of the lac operon.

A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter. A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.arrow_forward
