Answer:
The 6O2 is left out.
Explanation:
The reactants has 18 oxygens but the products only has 6 oxygens. Adding 6O2 would get us to 18 oxygens on both sides.
This is not part of the equation, but energy could be considered as well.
Explanation:
Cell Cycle Regulators. The cell cycle controls replication and apoptosis, prevents uncontrolled cell division (tumor formation), and may involve detection and repair of damage to DNA. ... Sigma offers a host of cell cycle regulators such as antimitotics, mitotic inhibitors, and cytokinesis inhibitors.

Answer:
osmosis
Explanation:
Movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane.
Explanation:
In neurology, postganglionic nerve fibers are autonomic nerve fibers from the ganglion to the effector organ. These, unlike preganglionic fibers (whose sole neurotransmitter is acetylcholine) have a variety of neurotransmitters to fulfill their functions.
Neurotransmitters
The neurotransmitters of postganglionic fibers are varied, and are distributed as follows:
In the parasympathetic nervous system, neurons are cholinergic (Acetylcholine is the primary neurotransmitter)
In the sympathetic nervous system, neurons are mostly adrenergic (norepinephrine-epinephrine and / or norepinephrine, both have the same chemical structure, but epinephrine has a methyl group unlike norepinephrine that has a hydrogen, instead of a methyl group - act as the primary neurotransmitter) Two exceptions to this are the sympathetic innervation of the sweat glands and the piloerector muscles where the neurotransmitter in both pre and post ganglionic synapses is acetylcholine and in the vessels of the renal cortex where dopamine is used as the main neurotransmitter. Another exception is the sympathetic innervation of the medulla of the adrenal gland, which is innervated by preganglionic fibers, and subsequently uses acetylcholine as a neurotransmitter. Adrenal medulla cells are, in fact, modified postganglionic neurons that secrete epinephrine and norepinephrine directly into the bloodstream rather than a synapse.
In both divisions of the autonomic nervous system, postganglionic neurons express nicotinic acetylcholine receptors to receive signals from preganglionic neurons.
