Answer/Explanation:
Natural selection - over time - selects for traits that improve fitness. A butterfly with wing coloration that looks like a hungry owl would certainly be a deterrent to their natural predators, such as smaller birds. This is because the owl is the predator of the smaller birds, and their instinct is to avoid the owl.
If a mutation arose that resulting in coloration that looked like an owl, (or at least slightly menacing) this would be beneficial to the butterfly, as it would be more camouflaged from predators. This means it would be more likely to reach reproductive age and pass the mutation onto its offspring, who would also have a competitive advantage.
Over time, this would lead to a population of butterflies with coloration that looks more and more owl-like .
Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.
<h3>What is Acetylcholine?</h3>
Acetylcholine is a chemical messenger (i.e., a neurotransmitter) that is used to transmit signals inside the body.
Acetylcholine broken down is due to its hydrolysis, which ends cell signaling between brain synapses.
In conclusion, Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.

Answer:
Multicellular organism is the example of complexity of the natural world.
Explanation:
Multicellular organism such as human which is made of billions of cell. Each cell perform a specific function. The function of one organ is different from the other organ. For example, brain of human is made of millions of neurons which takes instructions from brain to the organs and bring messages from organs to the nervous system in the form of electrical impulses. In short every system in our body is full of complexity.
