I'm doing a project with my friends for bio class. We have to make a book about photosynthesis and this is one of our topics; however, we can't figure out what organisms do glycolysis.

Yes, I know I can go to places like Yellowstone and see large herds of - something - but what am I looking at, exactly? Are the animals in these herds purebred bison or the results from crossbreeding bison with cattle? If they are hybrids, are purebred bison extinct, leaving only the hybrids as the surviving species?

Are there any sites that offering a combination of Google Maps or Yahoo Maps with weather data (e.x. temperature, wind, etc...) for all the countries of the world?

A barometer measures atmospheric pressure. The air in the atmosphere exerts a force called pressure that constantly changes due to moving weather systems. Therefore, in conjunction with other meteorological instruments, a barometer helps to predict clear or rainy weather.

In 1643, Evangelista Torricelli invented the first barometer. He figured that if he had a vacuum, an airless space, he could compare the ever-present atmospheric pressure with zero pressure. So he placed a vacuum contained in a glass tube on top of a larger container of mercury. The air presses down on the mercury's exposed surface and pushes it up into the tube. The higher the mercury level, the greater the air pressure. Originally, the units of air pressure were just millimeters of mercury. People could finally measure the force of air.

Since the advent of "Torricelli's tube," others developed the aneroid barometer that works without liquid. In this instrument, a flexible metal accordion box that resembles a bellows is partially squeezed to a medium pressure. Then, if air pressure rises, the bellows contract because the air inside them takes up less volume. An aneroid barometer often connects to a recording device, together forming a barograph. A pen moves against a rotating cylinder whenever the bellows moves, and thus creates a visual aid to the pattern of falling and rising air pressure. The barograph remains a basic instrument of modern meteorology.

Used in conjunction with a thermometer, a barometer can make general weather predictions. While weather is very complex, storms more or less follow certain patterns of high and low pressure systems. In simplified terms, a rising barometer means wind, frost, or clear skies, while a falling barometer indicates coming storms. A steady barometer might mean precipitation or sun. Weather forecasters look at the relative change at different places, taking into account how air pressure changes with elevation.

Some home hobbyist barometers still convert units to inches or millimeters of mercury, whether or not mercury is present. The International Meteorological Society has declared the universal unit of pressure to be the hectopascal. For example, 1016 hectopascals equals 30 inches of mercury (762.1 mm).

You are playing a game called “Deal or No Deal”, twenty-six cases are displayed at random with various amounts in each (from one cent to one million dollars). You select case number one and manage to eliminate all but two cases (your case and case two). One case contains one million dollars and one contains one cent. Howie Mandel ask: “Would you like to switch to case number two?” Is it to your advantage to switch to case number two?

Explain your answer.
