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:
Obligate anaerobes (Ans. D)
Explanation:
Gas gangrene is a bacterial infection which produces tissue gas in gangrene. This is caused by bacteria <em>Clostridium perfringens</em><em>. Clostridium perfringens</em> is a gram-positive, obligate anaerobic bacterium of the <em>Clostridium</em> genus. It is found in environmental sources & commonly found in raw meat and poultry.
Tetanus is a bacterial disease infected by <em>Clostridium tetani</em>, is an obligate anaerobic spore-forming bacteria. It is found in soil, dust and intestinal tracts of animals. Transmission of tetanus is commonly by contaminated wounds.
Among the listed plants above, the one that we can expect to grow lowest to the ground would be the hornworts. Hornworts are non-vascular plants which can be found both on water and land. Since these plants do not have a vascular system, it is hard for them to move water internally due to the force of gravity which explains why they cannot grow more above the ground.
Answer:
The correct answer is - The cell would be unable to produce.
Explanation:
Cyclin is a protein that helps in cell division to complete the various stages. It has an essential function, however, cyclin does not play role in enzymatic reactions bit bind with cyclin-dependent kinase enzyme they form maturation promoting factors which can phosphorylate specific proteins and result in many different stages of the cell cycle.
Mutation in cyclin gene that did not allow to produce cyclin protein will cease the cell cycle and there would be no future daughter cell and the cell would not be able to produce.
Heat from the Sun causes water<span> to evaporate from the surface of lakes and oceans. This turns the liquid </span>water<span> into</span>water<span> vapor in the </span>atmosphere<span>.
