Answer:
option d
Explanation:
Molecular sizes of gaseous molecules are very less. Volume occupied by the all the molecules of the gases are very less or negligible as compared to the container in which it is kept. Therefore, most of the volume occupied by gaseous molecules are negligible.
Volume occupied by the gaseous molecules are actually the volume of the container and its does not depend upon the amount, molecular mass or dipole moment of the gaseous molecules.
Therefore, the correct option is d ‘Because most of the volume occupied by the substance is empty space.’
Answer:
The A option is the correct answer: Non-native disulfide bonds form after beta-mercaptoethanol is removed, so the protein cannot refold correctly
Explanation:
Beta-Mercaptoehanol is responsible to reduce the four disulfide bonds present in ARNase; Urea deals with non covalente bonds. In presence of both ARNase is denatured.
If Urea is first removed by dialysis, and later is removed Beta-Mercaptoethanol, the enzyme recovers ist activity.
If Beta-Mercaptoethanol is first removed, disulfide bonds different from native use to be formed. As a result ARNase is not an active enzyme
b. False is the correct answer.
The standard unit for measuring mass is kilogram (kg), which is equal to 10^3 g. In chemistry, we use grams for measuring mass because we just usually use small amounts of stuff, so using grams is more sensible.
Hope this helps~
Explanation:
The ice cube which was solid has turned into the liquid water because the air temperature is warmer than the freezers. Which means the ice particles gather heat energy from the warmer air. Therefore the ice particles have enough energy to break apart (melt)into smaller particle arrangements.
