How does wind speed affect evaporation rates?

The air can hold some water, but for any given temperature, there is a limit to its water-holding capacity. When air has all of the water it can carry, it is called “saturated,” meaning that the relative humidity is 100 percent. When the air is saturated, the water’s rate of evaporation and condensation achieve equilibrium, meaning that water is evaporating into the air at the same rate that water is condensing out of the air. If the wind is not blowing at all, the molecules of water that turn into the gaseous state tend to accumulate right over the surface of the water. The relative hum..

Is SeF6 polar or nonpolar?

A polar molecule has a net dipole moment. In order to determine whether a molecule is polar, the valence shell electron pair repulsion rules should first be used to identify the three-dimensional geometry of the molecule. Then, the net dipole moment due to the polar bonds in the molecule should be determined. These bonds often have atoms of different electronegativities on their two ends. For example, selenium has an electronegativity of about 2.55, while fluorine has an electronegativity of about 3.98.

How do storm surges form?

Storm surges are formed as a hurricane or tropical storm moves across a large body of open water. Tropical weather systems have winds that are strong enough to produce a rise in sea level beneath the storm. The storm surge of a tropical weather system can cause intense flooding and even total inundation when the storm makes landfall in a coastal area.\nThere are many factors that determine the maximum potential storm surge that a weather system is able to produce including the size and intensity of the storm, its angle of approach to the coast and the slope of the continental shelf. The bulk o..

What takes up most of the volume of an atom?

To give some scale, if a hydrogen atom were the size of the Earth, its nucleus of a lone proton and neutron would be about 600 feet in diameter, leaving the rest of the Earth an empty vacuum. Electrons, while approximately 1800 times less massive than protons, have an unknown volume. Heavier elements have more subatomic particles and therefore a slightly higher ratio of subatomic material to empty space.

What are cells that do not have a nucleus called?

The genetic material of prokaryotes resides in an open area of the cytoplasm called the nucleoid. The DNA molecule is one double-helix structure that forms into a coil. Prokaryotes perform binary fission, a type of asexual reproduction. The single DNA strand replicates, and each strand moves to opposite ends of the cell. The cellular membrane between the two copies of DNA grows until the cell is twice its original size. Finally, the membrane pinches in between the strands, forming a cell wall. The identical sections separate into two new daughter cells.

What happens if you drink water contaminated with coliform?

Coliform bacteria are considered indicator organisms in that they alert testers to the possible presence of disease-causing bacteria in the water source, explains the Pennsylvania State College of Agriculture. The presence of the coliform bacteria suggests the existence of a path between the water supply and the bacteria source. Other types of disease-causing bacteria may use the same pathway to the water supply.\nThe three groups of coliform bacteria include total coliform, fecal coliform and E. Coli, advises the Washington State Department of Health. Total coliform bacteria are usually harml..

How do humans affect artificial selection?

Humans engage in the artificial selection of plants as well as animals. Kale, cabbage, broccoli and cauliflower, for example, have all been created from the mustard plant. By emphasizing some traits and de-emphasizing others, humans have created a number of different vegetables from the stock of a single, ancestral species.\nMany different pets look and behave as they do because of artificial selection. Fish hobbyists, for instance, have produced an incredibly diverse array of goldfish and other popular species. Many amphibians and reptiles that are popular among hobbyists no longer resemble t..

How does radiation affect seed growth?

UV-B radiation can also negatively impact a plant's ability to fight off diseases and can actually make them more susceptible to plant disease. This is due to the increased radiation impairing the cellular division, as well as impairing basic biological functions within the plants. This effect of UV-B radiation can especially be seen in ocean and freshwater plant life. Plants within bodies of water that are located too close to the surface can be exposed to more UV-B radiation from the sun than was naturally intended. Many of these effects can also be seen in places like Antarctica, where..

What is the meaning of criminal law?

In criminal law, a prosecutor for the state must prove guilt "beyond a reasonable doubt." A person who is found not guilty in a criminal case can still be sued by a victim in civil court. In a civil case, the requirement is to find a defendant liable based upon a "preponderance of the evidence." If a plaintiff wins in a civil suit, the defendant is not incarcerated, however the victim receives monetary payment or property as compensation.

Why should an effort be made to reduce the use of fossil fuels?

There are many things that can be done to reduce daily energy requirements, such as reducing hot water use, shutting down appliances when not in use and using fluorescent light bulbs instead of regular light bulbs. Properly weatherproofing the home, keeping curtains and windows closed at night and using upgraded insulation in walls can greatly reduce daily energy needs at home. Reusing or recycling waste like glass, metal or newspapers can also aid in reducing the amount of carbon monoxide that is released into the atmosphere.
