Answer:
The correct answer is cholesterol is nonpolar.
Explanation:
Cholesterol is a complex lipid is synthesized from acetyl CoA.cholesterol is an important constituent of plasma membrane.
Cholesterol is non polar in nature.As a result cholesterol is repelled by water and can be found between the layers of the phospholipid in the plasma membrane.
As cholesterol is non polar it is also hydrophobic in nature.
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
