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.
You can carry out research on reliable sources to identify what life was like in Jamestown, using the social, economic and political characteristics of the colony to produce your illustration.
<h3 /><h3>What was life like in Jamestown?</h3>
Jamestown corresponds to the first English settlement in America being considered the capital of the colony, it was located in Virginia.
In the 1600s, life in Jamestown was difficult, with high rates of violence, insecurity, lack of resources and diseases, and the first settlers found it difficult to settle in the place, where climatic and soil conditions were unfavorable for agriculture and subsistence.
Therefore, the period that comprises the years 1609 and 1610, became known as the <em>"Time of the Famine"</em> in Jamestown, which, due to the scarcity of resources, caused most of the settlers to die due to the precariousness of living conditions.

Galaxy is a whole bunch of planets rocks and stars in one galaxy.
A solar systom is when the other planets rotate around the main one. For example the galaxy that earth is located in is called the Milky Way and see there are many planets and rocks in this galaxy.
Let's look at the meaning of the four terms:
opportunity cost - this is a cost of an option not chosen, upon the choise of some option.
surplus - this is a situation where more goods are offered than are needed
<span>shortage - t</span><span>his is a situation where less goods are offered than are needed
price fixing
- this is an agreement between competitors to not lower a prize for a certain product.
So the correct answer is surplus!
