Answer:
Microsoft Paint is a simple raster graphics editor that has been included with all versions of Microsoft Windows. The program opens and saves files in Windows bitmap, JPEG, GIF, PNG, and single-page TIFF formats. The program can be in color mode or two-color black-and-white, but there is no grayscale mode.
Answer:
In aerobic respiration, glucose is completely broken down into carbon dioxide and water. However, in anaerobic respiration, the breakdown of glucose is incomplete. The end product of anaerobic respiration is lactic acid instead of carbon dioxide and water. This process occurs in oxygen debt. Hence, the amount of oxygen required to oxidize lactic acid to carbon dioxide and water is not present. Aerobic respiration produces 38 ATP whereas anaerobic respiration produces only 2 ATP molecules. However, in anaerobic respiration, the breakdown of glucose is incomplete.

In comparison, new media allows companies to target a narrow target audience through social media, paid online ads, and search results.Going with the Flow: How Electricity Powers the World
Simply put, electricity involves the flow of electrons, which are defined by current. There are two main kinds of current: DC or direct current – a ‘flow’ of energy like you get from a battery; and AC, or alternating current (like from your wall outlets) – which reverses the direction of electrons, allowing current flow to turn on and off. But that current must be sourced or created. Luckily, there are many different ways, ranging from the simplest static electrical charge produced by merely rubbing materials together, to the infinitely complex process of harnessing nuclear energy as a power source.
Infinite Potential: Common Energy Sourcing Options
Nearly all forms of sourcing energy involve turbine use. For fossil fuel generated power, this involves combustion for the production of steam and gases to rotate turbine shafts, which, when connected to a generator, convert this mechanical energy into electrical current. In renewable options, however, the source itself typically fuels turbine movement.
Natural Gas
Natural gas combustion alone, or as part of a furnace/boiler system, propels turbines to create energy.
Coal
Most power plants use coal-fired steam turbines to generate power, though a few convert coal to a gas before using it in turbines.
Petroleum
Petroleum can also be burned to produce combustion gases or steam to power turbines.
Nuclear Power
With nuclear power, nuclear fission produces the energy-generating steam necessary to spin turbines and generate electricity.
Hydropower
Hydropower from dams and other setups power turbines via flowing water.
Wind
Like giant pinwheels, turbines capture energy from the wind for conversion into electricity.
Biomass
Derived from plant and animal waste, materials are burned directly and used as other fuels to power turbines or internal combustion generators.
Solar
Energy from the sun is captured in photovoltaic solar cells, heating fluids to produce steam and drive turbines.
Geothermal
Heat from within the earth is harnessed to for heating water into steam to power turbines.
Energy Source Comparison: What’s America's Biggest Energy Source?
According to the U.S. Energy Information Administration, most of the electricity in the U.S. is created through the use of fossil fuels.
