Why do scientists like nature to be in a steady state? Why would a double blind design for an experiment be useful? Why are endocrine disruptors so difficult to study in humans? Why do hot springs exist? Why is high-LET radiation more destructive to biologic matter than low-LET radiation?
A fatty acid is a chain of carbon, oxygen and hydrogen atoms with a carboxyl group on one end. Fatty acids are classified on the basis of how many carbon atoms are in the chain, as well as how many double bonds exist within the molecule. Fish contain a variety of fatty acids, but t...
VRIF is an interesting idea as it’s 50% stocks and 50% bonds with 4% distribution. If you cares more about the distribution and do not care too much about price appreciation, this ETF might suite you well. I think more time is needed to see how this ETF will perform though. Reply...
How do the two strands of DNA come together to give the double helix structure? What kind of intermolecular force is involved in this part of the molecule? How can four guanine bases be held together to form a planar structure held ...
Why does the phenomenon of half life exist in elements? Why can stem cells become any type of cell? what is SO4 and why does it have a charge of -2? Why is SO_2 non polar whereas SO_3 is polar? Why do composite numbers have more than two factors?
Another tool the Federal Reserve uses to influence the economy is “forward guidance,” which lets the public know what the monetary policy will likely be. However, it does not explicitly state what the Federal Reserve intends to do. Instead, the communication focuses on the conditions that may...
aThus,the above finding rises the question of the reason why the yield is higher when using the E isomer.It is clear that if the polymer cannot react with the active species due to steric hindrance around the polymer double bonds,the termination reactions which are linked with this reaction ...
Proteins are polymers, and yet the language used in describing their thermodynamics and kinetics is most often that of small molecules. Using the terminology and mathematical descriptions of small molecules impedes understanding why proteins have evolved to be big in comparison. Many properties of the...
更新2: Please e back.更新3: Please e back michael 更新4: Ca=N-Ca-N=Ca is the molecule of Ca3N2. My question is why Ca2N2 does not exist. But cheungwaito gave an opinion saying that Ca3N2 is not stable? I do not understand.It is impossible to form only one ...
