What electrical device powers the RFID?
The RFID is powered by its own antenna. When in the presence of a pulating magnetic field, the antenna generates a signal that can power up the RFID, causing it to generate its code on top of that field.
What is industrial erosion?
In industry erosion is a destruction of a material due to an influence of elements, that have high speed. For example, in turbomachinery erosion can be detected on the blades of turbines or compressors. It's appearance is related to presence of particles of water (as a rule) in steam/air, that move with a high speed against the blades, causing destruction of the latter. Usually it looks as small chipmarks on the surface. Erosion causes loss of efficiency of blades, and finally - can cause its' complete destruction, and as a result - severe damage of the machine.
How can scientists use plastids to transfer characteristics from one organism to another?
A plasmid is a circular double stranded DNA usually found in bacteria. Most of them do not have specific functions and altering them does not hamper the bacteria possesing them. A gene of interest can be annealed to this plasmid so as to make the concerned bacteria produce a particular product. Since the bacteria can now produce a new product, the plasmid has been used to alter the characteristics of the organism.
How do you use the word flue in a sentence?
"The flue on the chimney was closed, causing smoke to move out into the room." "Damaging fires can occur when unburned material called creosote accumulates on the metal flue and in the upper chimney."
Does porosity affect the strength and properties of building materials?
Yes. Porosity is the void space between grains or clasts of a solid material such as the gaps between the grains in sandstone. Rocks that have higher porosity are typically less stiff at small strain values than more porous rocks as the initial deformation closes up the pore spaces which is relatively easy to do compared to causing deformation of the solid clasts. Pore spaces are also preferential pathways of weakness through a material and as such fractures are more likely to form connecting up porous regions of a solid. As such the more porous a given material, the easier it will be for a fracture to propagate through it. Also porous materials are more likely to contain water which can have a signficant impact by causing significant reductions in the materials the compressive strength.
Why do you think Griffith called the mystery material the transforming principle?
The material whatever it was, it contained information that changed the harmless bacteria into disease causing bacteria.
Which new phenomenon did Griffith focus on during his work with pneumonia causing bacteria and mice?
transfer of genetic material through transformation
Which new phenomenon did Griffith focus on during his work with pneumonia-causing bacteria and mice?
transfer of genetic material through transformation
Why is the presence of inflammable material a sources of danger in a workshop?
Inflammable ( and flammable) means something can easily be ignited- like gasoline. Workshop may have sparks or flames that would ignite that material, causing a fire.
What traps disease causing bacteria?
Mucus in the respiratory tract traps disease-causing bacteria.
What is a disease causing bacteria?

What is incubation used for in culturing?
When doctors are trying to determine what bacteria is causing an illness they sometime get a sample from the person and swab it on a shallow glass dish that contains a material the bacteria like and grow on. Once the bacteria has grown into colonies technicians look at them under a microscope to determine what the bacteria is. The process of growing the colonies of bacteria is called culturing
Explain how the bacteria in griffith's experiment were transformed?
The harmless living bacteria took in pneumonia-causing DNA(genes) from the heat-killed, pneumonia-causing bacteria, as a result of which the harmless bacteria changed into bacteria that cause pneumonia.
Do bacteria causing sickness?
Bacteria cause sickness but it helps you too
What is the medical term meaning disease-causing bacteria?
pathogenic bacteria
What health risks are associated with the presence of coliform bacteria?
Coliform bacteria are organisms that are presentin the environment and in the feces of all warmblooded animals and humans. Coliform bacteria will not likely cause illness. However, their presence in drinking water indicates that disease-causing organisms (pathogens) could be in the water system.
Which bacteria helps milk to change into curd?
Rennin deactivate the casein micelles in milk, causing a distinct separation of curd protein (solid) and whey protein (liquid).
