Answer:
The correct option is: "Vitamin B12 (cobalamin) is not found in the vegan diet and is very low in the lacto-vegetarian diet"
Explanation:
Homocysteine is a VERY IMPORTANT type of amino acid, a chemical that the body uses to make proteins. Normally, vitamin B12, vitamin B6, and folic acid break down homocysteine and transform it into other substances that the body needs. There should be very little homocysteine left in the bloodstream. If you have high homocysteine levels in your blood, that could be a sign of a vitamin deficiency of the vitamins listed above, a heart condition, or a rare inherited disorder.

Answer:
What is most widely accepted today is the giant-impact theory. It proposes that the Moon formed during a collision between the Earth and another small planet, about the size of Mars. The debris from this impact collected in an orbit around Earth to form the Moon.

Explanation:
Polymerization is the process whereby two or more monomers link together to form a compound of high molecular mass called a polymer.
There are two kinds of polymers;
-Addition polymers
-Condensation polymers
Addition polymers are formed by the joining of two or more monomers to form a polymer without the elimination of a small molecule.
Condensation polymers are formed by the joining of two or more molecules to form polymers with the elimination of a small molecule.
The main difference between polyethene and polyester is that polyethene is an addition polymer while polyester is a condensation polymer.
In polyethene, ethene molecules are joined together having the repeating unit as [-CH2-CH2-]n.
In polyester, the polymer arises from the reaction of carboxylic acid and an alcohol and loss of water molecules.
The mass of electrons, protons, and neutrons:
electrons 9.10938291*10^-31 kg
protons 1.67262178*10^-27 kg
neutrons 1.6749*10^-27 kg
the mass of electrons is way smaller than both, the mass of protons and neutrons
therefore, 1) the mass of 2 electrons is the smallest
