Is there bacteria in toilet water?

The toilet does not have to be in use for the bacteria to be present. Scientists from Leeds University found bacteria on the top and sides of the toilet and the floor, even when no one had flushed in a while. The bacteria levels are at their highest directly after flushing, but contaminated droplets appear on surfaces nearby even an hour or so after that last flush. Keeping the lid closed is a great way to control the spread of this bacteria.

What erupts from a volcano?

Magma is molten rock formed by the high temperatures underneath the Earth´s surface in the lithosphere, the lower part of the Earth´s crust and the upper part of its mantle. The molten rock is less dense than the rock above it, causing it to rise and eventually be released above the Earth´s surface. There are about 1,500 active or potentially active volcanoes on Earth.

What is a single point of 1 inch in height?

The term pica is used to reference other measurements in printing and typesetting besides the font size. Normally, it is used in reference to margins and page width. The term "point" does refer to type sizes. An example of this is setting a font to 72-point type face. The printed letters in this size will be 1 inch in height. The typical font type used in standard print is 12 point.

What are some water conservation companies?

The Irvine Company is one of the oldest groups in conservation, and it has focused on environmental consciousness and sustainability since the company's creation in 1864. Nalco is another company dedicated to water conservation efforts, and it focuses on improving the quality of the water as much as making sure that there is enough water to support humans over the long-term. The San Jose Water Company promotes water conservation as a large part of its activities.

How do you convert 157 cm to inches?

Set up the problemWrite out the information as a multiplication problem. Start with the given information you are converting from on the left and multiply it by the conversion factor. Make sure the unit you are converting to is in the numerator of the fraction.\n\nIt looks like this: 157 cm x 0.1 in/2.54 cm.Cancel the unitsSince the centimeters unit appears in the numerator on the left side and the denominator on the right, you can cancel them out, which leaves you with only inches.\n\nThe problem now looks like this: 157 x 1 in/2.54.SolveSimply divide 157 by 2.54 to arrive at the answer. Make..

What are the unique characteristics of Jupiter?

Jupiter is about 318 times as massive as Earth. Even the Great Red Spot is about two or three times bigger than Earth. Astronomers believe that if Jupiter had been more massive, it would have ignited and become a star itself.\nJupiter has actually shrunk in size since it was first formed. Scientists believe that the planet is shrinking at the rate of about 0.8 inches per year. It was also much hotter when it was first formed than it is as of 2014.\nBesides the Great Red Spot, Jupiter has bands of swirling cloud layers. The Great Red Spot also rotates counterclockwise and takes six days to circ..

What is the difference between ATP and ADP?

ATP stands for Adenosine Triphosphate. It is made up of an adenosine molecule and three inorganic phosphates, or a triphosphate. When one of these phosphates is removed, the energy that keeps human beings alive is produced. Therefore it is a crucial reaction in order to sustain life.When one of the three phosphates are removed the resulting compound is called ADP, Adenosine Diphosphate.ADP can be converted back into ATP so that it can be used again. Energy is required to do this, but the but there is an overall gain in energy when the process occurs.ATP is constantly being used by the body, so..

What are the two kingdoms of bacteria?

Although both Archaebacteria and Eubacteria are prokaryotes, meaning they do not have membrane-bound structures called organelles, the two kingdoms have so many differences between them that each belongs to a separate domain. The other four kingdoms, protists, fungi, plants and animals, belong to a single domain.\nThe Archaebacteria comprise organisms that live in hostile environments such as hot springs, salt water and deep sea vents. The Eubacteria include the bacteria that are more familiar to humans. The cyanobacteria, or blue-green algae, belong to the Eubacteria. Other Eubacteria cause h..

What are the advantages of using radio telescopes?

Unlike visible light, radio waves are not absorbed by clouds, so astronomers can make observations even during stormy weather. And while visible light is somewhat distorted by Earth's atmosphere, radio waves are so long that they are not distorted, giving a more accurate picture. In addition, the sun produces a lot of waves in the visible spectrum, but not a lot of radio waves. Because of this, optical telescopes can operate only at night, but radio telescopes can operate day and night.\nMost objects in the universe emit radio waves. Some are difficult or impossible to observe in differen..

What is the oxidation number of oxygen in H2O2?

H2O2, or hydrogen peroxide, can act as an oxidizing agent as well as be oxidized. This means that the peroxide is able to gather two more electrons and for a hydrogen ion. This would further change the oxidization number of the oxygen in the ion to -2. Peroxide can also act as a reducing agent, which means that the molecule loses two electrons and becomes an O2 molecule. The oxidation number of the oxygen then becomes zero.
