What is a MEME? What purpose do they serve? Are they harmful or beneficial? Why?

Explanation:

Memes may be interpreted as being inherently harmful, since, according to some scholars, memes are parasites or viruses of the mind; once assimilated into the human mind, their chief purpose becomes their own replication, with humans having little or no control over them. Some memes, however, are benign or beneficial but can become dangerous because, after they have been seeded in the human mind, they lend themselves to being misused or abused.

Hope this helped you!

memes are very beneficial to society.

to write complex sentences, we must use subordinating conjunctions.  

all the complex sentences begin with a subordinating conjunction and when it occurs, a comma must be place at the end of the dependent clause. on the contrary, if the sentence begins with an independent clause, then no comma is used.
