I believe your answer would be an atom.
Classical Greek philosophers, notably a man named Democritus, who lived in Greece in the 5th century was interested about the world around us. He thought up a very simple situation: If you cut something in half (like a log), the two pieces left can cut into even smaller pieces, which can cut again, and so on down to splinters. Yet, even a splinter could be cut in half. He questioned, "Whats the smallest that something can be cut?" He answer was that, at some very, very small size, you would reach a piece of the object that was 'atomos', Greek for uncuttable.
If you had a block of iron and let's say you kept cutting it into pieces, you would, in theory, reach an extremely small piece which could absolutely not be broken down-- it was the basic building block of iron. This was, and is, a powerful idea that gives reason for all sorts of things related to chemistry and the world we live in-- like how our bodies digest food <span>(since everything is made up of just a limited number of types of atoms (the elements), we can ingest food in one form, break the food down into small groups of atoms, and put the atoms back together as parts of our growing bodies). Modern chemistry is formed on atomic theory. Atoms are almost unbelievably small, one of your hairs is about a million atoms wide, and a speck of dust you can see might as well contain trillions of atoms.
I got my answer and reasoning from a website called "scienceline.ucsb.edu". It goes way more into depth for your answer, you might want to check it out. I just chose bits of info that directly give reasoning as to why your answer would be An atom.
Good luck on your assignment. </span>
We examined the biogeographic patterns implied by early hominid phylogenies and compared them to the known dispersal patterns of Plio-Pleistocene African mammals. All recent published phylogenies require between four and seven hominid dispersal events between southern Africa, eastern Africa, and the Malawi Rift, a greater number of dispersals than has previously been supposed. Most hominid species dispersed at the same time and in the same direction as other African mammals. However, depending on the ages of critical hominid specimens, many phylogenies identify at least one hominid species that dispersed in the direction opposite that of contemporaneous mammals. This suggests that those hominids may have possessed adaptations that allowed them to depart from continental patterns of mammalian dispersal.

Answer:
Enzymes are catalysts, meaning that they lower the activation energy. Lower activation energy allows for a faster process so enzymes speed up chemical reactions.
Explanation:
Enzymes are usually proteins that act on molecules called substrates and bind to a region of the enzyme, called the active site. This is the site where catalytic function occurs. The catalytic function is to reduce the activation energy necessary to start biochemical reactions, allowing the formation of a product to be quicker.

QUESTION:
amino acids come from which type of organic molecule?
ANSWER:
<em><u>Proteins</u></em>
Proteins are polymers made up of nitrogen-containing monomers called amino acids. An amino acid is a molecule composed of an amino group and a carboxyl group, together with a variable side chain.
