Mars has a diameter that is approximately half that of Earth. If the interiors of these planets are heated by radioactive decays, how does the heating rate of the interior of Mars compare to that of Earth? a. The heating rate of Mars is 0.125 times that of Earth. b. The heating rate of Mars is 8 times that of Earth. c. The heating rate of Mars is 0.5 times that of Earth. d. The heating rate of Mars is 4 times that of Earth. e. The heating rates are about the same.
Heating Rate Comparison The heating rate of a planet's interior due to radioactive decay is proportional to its volume, which is determined by its radius cubed. Since Mars has a diameter...

Question 12: The last step in the protocol is to autoclave the 10x PBS solution. Why do you think this step is important? Look up the definition of autoclave if you are unsure what it means.
Autoclave is used to sterilise solutions using high temperature and pressure. As PBS is used in various assays (immunocytochemical and immunofluorescent staining, cell culture, protein purification, etc.), it is important...

An enzyme completely complementary to its substrate would be a very poor enzyme. - Explain why?
Such an enzyme impedes the reaction, stabilizing the substrate instead. When the enzyme is complementary to the substrate the ES(enzyme-substrate) complex is more stable and has less free energy in...

Suppose you are working in a lab to optimize enzyme activity and you observe that the enzyme activity decrease with increase in time. What could be the possible reason/s?
The reasons can be as follows>We know that the enzyme is unstable under the assay conditions.>Enzyme activity decreases due to the change in pH>The reason can be that the substrate...

used culture plates are better sterilizedin the laboratory using........?
a)0ven
b)incubator
c)autoclave
d)water bath
Autoclave is the best choice because it allows creating temperature over 100 C due to development of high pressure. It ensures the efficient destruction of bacterial spores, which may survive...

10 kg of water is boiled into steam. What will be the mass of steam created
A water molecule is a water molecule, irrespective if it is densly packed with other water molecules (forming a liquid phase) or if it is widely separated from other water molecules (forming a vapor phase). So it seems...
