You will be given a scenario that applies to the next few questions. Please look at the prompt at the bottom to see what you are to fill in. You are exploring a mangrove forest along a tidal river. The air is humid, roots twist above and below the water, and the mud is littered with crabs and fallen leaves. As you move around, you notice: Two species of hermit crabs near some mangrove roots appear to be battling over a food-rich area. The larger blue hermit crab repeatedly pushes the smaller red hermit crab out of the area. After a short while of many failed attempts to access this food rich area, the red hermit crab moves to another section of the mangrove in search of food. Looking under the water, you notice a shrimp digging a large burrow. In front of the shrimp is a small goby fish. After observing for several minutes, a large snapper fish swims near, the goby instantly alert swims into the burrow, alerting the shrimp who instantly follows into the burrow for safety. Along the muddy edges of the mangrove, you find mudskippers. Healthy mudskippers are brown with blue spots, but you notice several dead mudskippers with small red, worm-like organisms moving on their bodies. Further along the edge, you spot what appears to be a tree branch moving slightly. Upon closer inspection, it is actually a stick insect, perfectly still and blending into its surroundings. As you continue exploring, you think about how all these species interact, survive, and compete in this unique mangrove ecosystem. 5. The stick insect remains motionless and resembles a branch. What type of adaptation is this? (I am looking for a specific adaptation term so do not say camouflage, this is too general)

In November 2020, the price level in the U.S. was . At the same date, the price level in the Eurozone was . One year later, the price levels were and . During this 12-month period, the real exchange rate was constant. The nominal exchange rate (E) is reported in euros per dollar (i.e., how many euros do we need to purchase one dollar). Assuming that the law of one price holds for all goods & services and using the information above, calculate the rate of change of E during this time (in percent). Round your answer to the nearest tenth of a percent.

A population of mice lives in a field where the ground color is a mix of light soil and dark rock patches. Light-colored mice are easily seen on dark rocks, and dark-colored mice are easily seen on light soil. However, mice with intermediate coloration are visible in both environments and are more frequently eaten by predators. Over time, the population shifts toward more light and dark mice, with fewer intermediate individuals. This is an example of __________ selection.
