Thirteen of the animals are sampled and the mean calcium concentrations in their coelomic fluid is found to be 30mmole/kg with a standard deviation of 1.8mmole/kg. The researchers want to know whether the mean calcium concentrations of this species of marine arthropod differs significantly from that of the surrounding environment which was 32mmole/kg. Please help the scientists. 1) Calculate t; 2) Figure out 3) Conclusions.

Understanding regional tectonics using beach balls Part I: Remember beach balls and fault types Figure 1 shows that we can distinguish the different types of faults (normal, reverse and strike- slip) using beach balls. Beach balls describe the focal mechanism occurring at a given fault. Figure 1: Different types of faults and associated focal mechanisms. The black parts are under compression and the white parts under tension. For the strike-slip faults, the circle with the cross means that the block is sliding further from you, while the dot inside the circle means that the block is sliding towards you. For all three cases, the direction of the fault is through the page. Part II: Using beach balls to understand the regional tectonics around Turkey Figure 2 shows the focal mechanisms for the eastern Mediterranean region. 1) Draw arrows showing the relative motion across some of the main fault zones (shown with eleven pairs of dots), using the beach balls on Figure 2 and help from Figure 1 . Note that for strike-slip faults, there are usually two possibilities (eg., left-lateral strike slip fault oriented N-S or right-lateral strike-slip fault oriented W-E). However, here, you already have the direction of the fault, so there is only one possibility. 2) Draw arrows showing the motion of the three southern plates relative to Eurasia. That means that Eurasia, in this exercise, is not moving Motion of the three southern plates are shown with four boxes. A good way to work this problem is to imagine cutting the map on the next page map into pieces along the plate-bounding faults, tape Eurasian to a table, and try sliding the blocks to see if you can find a way to move them that is consistent with the focal mechanisms. Figure 2, next page: (top). Focal mechanisms for the eastern Mediterranean region. (bottom) Topographic and bathymetric maps to be completed with relative motions of the plates. There are volcanoes on near the west-most box. Why is this? 4) Compare the African and Arabian arrows (i.e, velocity vectors). Which is larger? 5) There are large mountains in Iran and the Caucuses (in the NE portion of the map, see also name of countries on Figure 4). Why is this? 6) There are elongated islands, peninsulas and inlets in Greece that trend SE-NW to E-W. Why is this? Figure 3: Major faults in the Mediterranean region..

Understanding whether a glacier is growing, shrinking, or staying the same in terms of ice volume is important. Glaciers serve as an important indicator of changing climate. Thus, it is important to understand how ice accumulates and how ice is lost to determine if it is gaining more than it is losing or vice versa. Glacial ice is lost through several processes. Which of the following is not one of these processes: calving melting sublimation firn metamorphsis all of these choices are ways ice is lost from a glacier.

through the oxidation of metal ions in seawater. Question 8 1 pts The amount of CO2 in the atmosphere is very small (0.04%) because CO2 is in great demand by photosynthesizers as a source of carbon for growth. CO2 is very soluble in water, though; the proportion of dissolved CO2 in water near the surface is about 15% of all dissolved gases. Because CO2 combines chemically with water to form a weak acid called saturation. C water can hold perhaps 1,000 times more CO2 than either nitrogen or oxygen at.

The southeastern United States receives substantially more precipitation than the Southwest. Why? Warm ocean water off the East Coast warms the air and produces summer-time storms. Cool water along the coast of California cause the air to be drier and more stable. The Atlantic High advects warm humid air northward into the US Southeast. All of these make the Southwest arid, compared to the Southeast. None of these help explain why the Southwest is arid, compared to the Southeast..
