Metamorphic rocks are formed from other rock that has been subjected to very high temperature and pressure.
When one of the earth's plates comes in contact with another either by both traveling opposite directions, straight into each other, or from one slipping under the other (subduction zone), the pressure/friction of the plates against each other melts the rocks and after they cool they are metamorphic. Example is in Washington state when the Juan de fuca plate is going under the North American plate the pressure/friction of this melts the rocks which then form metmorphic rock.
Answer:
Climate change is rapidly becoming known as a tangible issue that must be addressed to avoid major environmental consequences in the future. Recent change in public opinion has been caused by the physical signs of climate change–melting glaciers, rising sea levels, more severe storm and drought events, and hotter average global temperatures annually. Transportation is a major contributor of carbon dioxide (CO2) and other greenhouse gas emissions from human activity, accounting for approximately 14 percent of total anthropogenic emissions globally and about 27 percent in the U.S.
Fortunately, transportation technologies and strategies are emerging that can help to meet the climate challenge. These include automotive and fuel technologies, intelligent transportation systems (ITS), and mobility management strategies that can reduce the demand for private vehicles. While the climate change benefits of innovative engine and vehicle technologies are relatively well understood, there are fewer studies available on the energy and emission impacts of ITS and mobility management strategies. In the future, ITS and mobility management will likely play a greater role in reducing fuel consumption. Studies are often based on simulation models, scenario analysis, and limited deployment experience. Thus, more research is needed to quantify potential impacts. Of the nine ITS technologies examined, traffic signal control, electronic toll collection, bus rapid transit, and traveler information have been deployed more widely and demonstrated positive impacts (but often on a limited basis). Mobility management approaches that have established the greatest CO2 reduction potential, to date, include road pricing policies (congestion and cordon) and carsharing (short-term auto access). Other approaches have also indicated CO2 reduction potential including: low-speed modes, integrated regional smart cards, park-and-ride facilities, parking cash out, smart growth, telecommuting, and carpooling.
Explanation:
Answer:
The reduced form of cytochrome c more likely to give up its electron to oxidized cytochrome a having a higher reduction potential.
Explanation:
Electrons from NADH and FADH2 flow spontaneously from one electron carrier of the electron transport chain to the other. This occurs since the proteins of the ETC are present in the order of increasing reduction potential. The reduced cytochrome b has lower reduction potential than cytochrome c1 which in turn has a lower reduction potential than the cytochrome c.
Cytochrome c is a soluble protein and its single heme accepts an electron from cytochrome b of the Complex III. Now, cytochrome c moves to complex IV which has higher reduction potential and donates the electron to cytochrome a which in turn passes the electrons to O2 via cytochrome a3.
Answer:
b. pass through pores in the capillary endothelium
Explanation:
The fenestrated capillaries and sinusoids have pores in their endothelium. These pores or the intracellular clefts vary in size between the fenestrated capillaries and sinusoids. Sinusoids have larger intracellular clefts. The pores serve as a passage for the movement of water-soluble substances, proteins and other substances that cannot cross the hydrophobic interior of the cell membranes.
Water-soluble hormones also cannot pass through the capillary walls. Therefore, these hormones pass through the pore or the fenestrations present in the endothelium of capillaries.
