Answer: The primary motor cortex for control of voluntary muscles is found in the precentral gyrus of the frontal lobes.
Explanations:
The primary motor cortex is one of the important brain areas involved in motor function. It is found in the precentral gyrus of frontal lobes. It control voluntary muscles and generate impulses needed for movement execution.

Answer:
Ribosomes, Cell membrane
Explanation:
Ribosomes can be described as structures which are involved in the production of proteins. Ribosomes are hence known to be the protein manufacturing units of a cell. As enzymes are also proteins,they will be synthesized in the ribosomes.
Cell membrane can be described as the membrane which is present outside the cell or which separates the cell from the external environment.
For an enzyme to pass through the external environment, it will have to pass through the ribosomes and the cell membrane.
ID isn't even genuine science, and it's an affront to religion too: their hypotheses make God look moronic and compel him to things that we don't yet get it. What ID advocates do is they discover something that isn't yet comprehended (at a certain point, it was a bacterial flagellum) and essentially wave their hands and say "God did it!", and afterward when that thing has been legitimately clarified by genuine researchers, they discover something else that hasn't been clarified yet and rehash the process.
