Science
The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.

Yes. All the natural sources of food can be contaminated withresidues of pesticides etc., for example, you can find traces ofDDT and PCBs in the body fat of penguins. Also, most foods containwater, which is a chemical, and foods themselves are organicchemicals, which means that they contain carbon,...

Yes, if you add plenty of water. When boiling ham or bacon we oftenput it in water, bring it to the boil, and then discard the first water and replace it for the restof the cooking. This gets rid of some of the salt. However, if youhave a liquid (e.g. a soup or gravy), boiling it will onlyevaporate...
Mesophyll cells.
Microbial contamination (such as mold and yeast) can enter after the bottle is opened. Magnesium citrate formulas give microbes an ideal environment to grow.
Oxidation. At high temperature magnesium ignites - and that iscalled combustion.
1 metric ton of dolomite has a volume of approx 0.35 cubic metres.

Causes of variation is random mutation. Random mutationsconstantly occur in the genomes of organisms; these mutationscreate genetic variation. If all living things were same, we willall use up one type of food as our nutrient source and eventuallywe will run out of food to consume.. making less...
Mercury's atmosphere contains small amounts of hydrogen,helium, and oxygen. It also has even tinier amounts of sodium,potassium, calcium, and magnesium. Some of the gas particles comefrom the solar wind. Others are made by radioactive decay or whenmicrometeorites smash into the surface.
It is suggested you do this to avoid microbial contamination as itattracts moisture from the air. Magnesium Citrate does notdecompose quickly. Under the proper conditions it should still befine to continue using the oral solution after 24 hours. Considerrefrigeration, tightly sealing the bottle, or...
we can do this technique by a proper method.first we have to takethe cut part of a root stem n then grind it by machine n thenspread this solution on chromatographic paper ......when the paperbecomes dry we can see the transition of different colours...

The volcanic mountain Haleakala is on the island of Maui, Hawaii, near 20.7° North latitude. (More precisely, it is located at 20°42â²35â³N, 156°15â²12â³W in central Maui.)
The neutron has about the same mass as the proton, each hasa mass a tiny amount greater than 1 AMU (atomic mass unit). Theneutron is the smallest bit more massive. The electron has a mass of just a bit over 5/10,000ths of an AMU.Extremely less massive in comparison, isn't it!
Indeed they are. Misconceptions rise about the same geographicfeatures. Like most names, the Rocky mountains was shortened to theRockies because people were too lazy to just say Rocky mountainsand instead said the Rockies, which leads to misconceptions likethis. Similarly, the Canadian Rockies ...
No. There is a single covalent bond between the two atoms of achlorine molecule.
760 kilometers is about 472.242 miles.
Abdominal pain and loss of appetite are very unspecific symptoms.They can stem from pretty much any disorder in thegastroinstestinal tract, and even from disorders elsewhere in thebody. A common gastrointestinal infection by rota- or noroviruses("stomach flu") for example can feel bad but might cure...
They have small holes in their shells.
No, the condition is caused by deficiency of the parathyroid gland.

If you're talking about wind power, then yes. Wind power is a renewable source of energy because wind is anatural, re-usable source. Wind power is generated by windturbines . To put it simply, the wind turns the blades, whichspins a shaft, which connects to a generator, making electricity.The...
It is neutral.
The shock absorbers on a car use the viscous properties of oil to absorb energy when the tire hits a bump. Oil is forced to flow through small holes inside the shock absorber as the wheel moves up, and again as it moves down to its normal position. Without shock absorbers, the car would continue...
Generally, the source of energy for cell functions is ATP orAdenosine triphosphate.
"Resin Based Paint" is the liquid in paint that suspends thepigment (leaving the resin behind, obviously) and transports themfrom the paint brush to the wall. The paint then evaporates andleaves the paint film behind.
The traditional answer is probably something like dimensions of a city or agricultural field or aircraft runway. But ANY length can be expressed in miles. The thickness of a human hair (say 100 micrometers) is approximately 6x10^-8 miles.

Transparent, biconvex intraocular tissue that helps bring rays oflight to a focus on the retina.
Usually we use a mechanical or electrical meter. Gas supplies cansimply drive round a counter. Electricity can be measured inseveral ways, for instance by using part of it to turn a disc whichin turn drives a counter. Essentially we measure how much power weuse and for how long. The unit is usually...
The salinity in isolated seas and salt-water lakes (for example,the Dead Sea) can be considerably greater. SO there's a highsalinity in the Dead Sea. :D

A room and a cell are alike in that they are isolated parts of acollection. The rooms have walls which separate them from the otherrooms of the house, and the cells have cell membranes (and cellwalls for plant cells) which separate them from the other cells inthe tissue. However, you can take the...

The electrical resistance between subatomic particles is farreaching from the atomic nucleus and electron cloud. Electrons arealso moving very fast. The probability cloud that determines wherethe electrons could be, the orbitals and the nucleus itself, arestill not solid objects. Keep in mind under...
The electromagnetic and strong nuclear forces are very powerful andrepulsive at close ranges. Put two atomic nuclei near each otherand they will push away from each other. Similarly if you put twonegatively charged particles near each other they will also repelat very close distances.
