Geiger-Muller tube is instruments requires you test three times the background of the work area.
<u>Explanation</u>:
These detectors are gas filled detectors and hence requires time for responding to the value. This time is taken because during this period it collects the electric charges and features of the electric circuit. It also gets stabilized during this period. This device has thumb rule i.e one must wait or hold for at the least 3 times the time constant before getting the precise and accurate reading. The time constant order is 10 seconds for the ionization chamber but for the Geiger counter it can vary from seconds to greater than 20 seconds
Answer:
The simplest mechanism by which molecules can cross the plasma membrane is passive diffusion. Passive diffusion is thus a nonselective process by which any molecule able to dissolve in the phospholipid bilayer is able to cross the plasma membrane and equilibrate between the inside and outside of the cell.
Answer:
Explanation:A mechanical wave requires an initial energy input. Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic waves require no medium, but can still travel through one.
Answer:
Carbon monoxide and antimycin are classified as electron transport inhibitors, FCCP as uncoupling agent, oligomycin as ATP synthase inhibitors, and bongkrekic acid as transport inhibitor.
Explanation:
The electron transport inhibitors refers to the substances, which get combine with distinct constituents of the ETC and prevent the function of the carrier. These substances binds with the carrier and prevent its transformation, which eventually results in halting of the process. The most commonly known electron transport inhibitors are rotenone, carbon monoxide, antimycin, etc.
A molecule that prevents oxidative phosphorylation in mitochondria and prokaryotes, or photo-phosphorylation in cyanobacteria and chloroplasts by inhibiting the production of ATP is known as ATP synthase inhibitors. The most commonly known ATP synthase inhibitor is oligomycin.
Similarly to oligomycin, FCCP or trifluorocarbonylcyanide phenylhydrazone is a potent uncoupler or uncoupling agent that prevents the synthesis of ATP by enhancing membrane proton permeability.
Bongkrekic acid refers to a highly toxic transport inhibitor that prevents the ADP/ATP translocase by combining with the inward facing site of ATP-ADP translocase.
