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.

Answer:
Option: False
Explanation:
When European came to the New World, they brought not only settlers but diseases that widespread in Central and South America. The diseases were smallpox, chickenpox, and cholera, among many others. The diseases became the result of the deaths of the major ancient civilizations like Maya, Aztec and others with its entire population (people). Portuguese tried to recruit Native Americans in the fields and mines in Brazil but failed because of the death of the Natives with coming contact with the diseases, those who survived often escaped to the forests.
