D, contains fluid that becomes more concentrated as it moves down into the medulla
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:
Coal.
Explanation:
Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.
Cells depend on the body environment to live and function. Homeostasis<span> keeps the body environment under control which keeps the conditions right for the cells to live and function. Not having the right body conditions can result in certain processes and proteins won't function properly.</span>
Answer:
b. a capsule
Explanation:
The capsule is mainly made up of polysaccharides and surrounds many bacteria. Capsule staining includes mixing of the bacterial cells with dye and spread out in a thin film on a slide. After air-drying, the cells appear as light-colored structures present in a relatively dark blue-black background. This occurs since the dye particles cannot penetrate either the cell or its capsule. Therefore, the given slide with a colorless ring around the cells in a dark background represents the presence of a capsule around the observed cells.
