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: Negative
When converting from scientific notation to standard notation if the power of 10 is negative we move the decimal to the left. If it is positive we move the decimal to the right.
Example: 3*10^-3=.03 and 3*10^3=300
Hey there! Cellular membrane and cell wall is your answer.
Answer:
because somethings could go out into the ocean and harm sea animals like turtles some get stuck in plastic and some die because of water poeple throw away and if that continued we may make all the sea life die because of that
Answer:
All enzymes are mostly protein, but many are only protein. These enzymes are known as simple enzymes. Enzymes that contain other things, “complex enzymes,” are called holoenzymes. A holoenzyme has two parts. The protein part is called the apoenzyme.
The enzyme substrate complex is a temporary molecule formed when an enzyme comes into perfect contact with its substrate. ... The substrate causes a conformational change, or shape change, when the substrate enters the active site. The active site is the area of the enzyme capable of forming weak bonds with the substrate.
Enzymes are protein molecules in cells which work as biological catalysts. Enzymes speed up chemical reactions in the body, but do not get used up in the process, therefore can be used over and over again. Almost all biochemical reactions in living things need enzymes. ... The study of enzymes is called enzymology.
