Answer:
D) One half of the carbon atoms of newly synthesized acetyl CoA.
Explanation:
It will be radioactively labeled because Malonyl CoA which contains 3 Carbon molecule is synthesized from Acetyl CoA which has 2 Carbon molecule.
This happens with the addition of ‘CO2’ with the help of the enzyme called acetyl CoA carboxylase.
Answer:
the answer is B
Explanation:
giving an atom a charge will not change what element it is
Answer:
D
Explanation:
This question is a little strange. C and D are very similar, but I would pick D.
Fluorine actually has the highest electronegativity of all the elements. This allows it to pull more electrons towards itself. Since electrons have a negative charge, this causes the fluorine end of the molecule to be more negative while the hydrogen is left striped of electrons and has it positively charged necleus exposed. This means that one end of the molecule is positive while the other is negative, which makes this molecule polar. The only reason I would pick D over C is that D addresses the second part of the question about the covalent bond. A covalent bond is simply when two atoms share electrons.
Let me know if this was right and I hope it helps.

a party mix:-) it would be a jar of cashews, peanuts, almonds, ettc.
Explanation:
if you can separate the nuts, it is heterogenous
<span>Recrystallization
is another method of purification of solids in which an impure solid is
crystallize repeatedly to obtain amore pure solid and a larger one. Ethanol is
better suited as solvent in recrystallization of benzene than acetone because
it becomes soluble with benzene at a higher temperature. Ethanol is non polar
and may react well with benzyl but acetone are is non polar. A difference in
their polarity, especially in heating both benzyl and the solvent can lead to
more impurities that cannot be removed.</span>
