Answer:
Codeine
Explanation:
Codeine is an opiate and is used to treat mild and moderate pain. It is also the main ingredient in prescription based cough suppressant. It belongs to a class of drugs known as opioid analgesics.
Codeine is a naturally occurring phenanthrene alkaloid with opioid agonist and can be extracted directly from the plant although most codeine is synthesized from the opium poppy.
Question: <em>The image below shows the life cycle of a plant. Which class does this plant belong to? </em>

Answer:
Explanation:
a biological taxon is spatially arranged. The geographic limits of a particular taxon's distribution is its range, often represented as shaded areas on a map. Patterns of distribution change depending on the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a population, or the distribution of the entire species as a whole (range). Species distribution is not to be confused with dispersal, which is the movement of individuals away from their region of origin or from a population center of high density.
You didn't really provide any possible answers here. However, it's very easy to say that the responsible actors for impulse transmission across the synapses from one nervous cell to another nervous cell is what we call neurotransmitters. These are special molecules that can have different effects when binding onto the required receptor sites.
