Answer:
. Vulnerability to
develop an addiction to drugs is dependent on genetic, environmental, social and
biological factors. In particular, the interactions of environmental and genetic factors
indicate the significance of epigenetic mechanisms, which have been found to occur in
response to illicit drug use or as underlying factors in chronic substance abuse and
relapse. Epigenetics is defined as the heritable and possibly reversible modifications in
gene expression that do not involve alterations in the DNA sequence. This review
discusses the various types of epigenetic modifications and their relevance to drug
addiction to elucidate whether epigenetics is a predisposing factor, or a response to,
developing an addiction to drugs of abuse.
Answer:
I agree with the poem's message that a positive attitude can make the world a better place.
Explanation:
As we can see in the poem, a positive attitude towards something unexpected or negative can be fundamental to life.
The poem has very few lines, however there is a great message in it. The speaker has an encounter with a raven that throws snow on him, and instead of getting angry, the speaker changes his mood in a positive way: he feels rued and saved.
The speaker could have been angered by this unexpected event and reacted in a bad way, even this could have ruined his day. However, he takes a positive and humorous attitude.
If we all did the same with the bad things that happen to us, the world would definitely be a better place.
