Answer:
A) The drug been abused by this individual is cocaine. Cocaine has been show to be powdery in nature with a distinctive white color.
B) The effects reported after use includes:
Feelings of euphoria.
Increased energy.
Inflated self-esteem.
Elevated mood.
Temporarily decreases the need for sleep.
Suppression of appetite.
Cocaine use may also bring about:
Feelings of restlessness.
Irritability and anxiety.
Panic.
Paranoia.
Etc.
C) Cocaine acts by blocking the reuptake of certain neurotransmitters such as dopamine, norepinephrine, and serotonin. By binding to the transporters that normally remove the excess of these neurotransmitters from the synaptic gap, cocaine prevents them from being reabsorbed by the neurons that released them and thus increases their concentration in the synapses. Due to this, the natural effect of dopamine on the post-synaptic neurons is amplified. The group of neurons thus modified produces much more dependency (from dopamine), feelings of confidence (from serotonin), and energy (from norepinephrine) typically experienced by people who take cocaine.
In addition, because the norepinephrine neurons in the locus coeruleus project their axons into all the main structures of the forebrain, the powerful overall effect of cocaine can be readily understood.
In chronic cocaine consumers, the brain comes to rely on this exogenous drug to maintain the high degree of pleasure associated with the artificially elevated levels of some neurotransmitters in its reward circuits. The postsynaptic membrane can even adapt so much to these high dopamine levels that it actually manufactures new receptors. The resulting increased sensitivity produces depression and cravings if cocaine consumption ceases and dopamine levels return to normal.
Dependency on cocaine is thus closely related to its effect on the neurons of the reward circuit.
The nan madol culture used indigenous materials to create communities based on blended social hierarchies
A hierarchical system organizes categories from top to bottom. For example, in a typical family system, parents have the most authority, followed by children, then pets. Look around; you might find examples of more hierarchies than you thought! The human body itself is a hierarchy.
First, the definition of social hierarchy is essentially a stratified ranking of group members along the dimension of value, with some members being better or worse than others, and a minority. members occupy the highest positions (Magee & Galinsky, 2008).

Answer:
Organizational assimilation
Explanation:
Based on the scenario being described it can be said that the mentor's job was to help Calvin through process known as Organizational assimilation. This term refers to a process in which new individuals that become part of an organization are adopted into the organizational culture. Which is what Calvin's mentor's job is by showing Calvin what to do and how to do it, which encompasses what the organizational culture is.
