Answers and Explanations

1. The application is easily accessible using various devices ranging from mobile phones to wearable technologies such as smart watches and Google Glass for hands-off use.
A "from . . . to" phrase must be preceded by "ranging" or a similar term, or at least a comma ("The application is easily accessible using various devices, from mobile phones to wearable technologies such as smart watches and Google Glass for hands-off use").

2. She told the audience about transsexual teenagers who are bullied, beaten up, and murdered or who kill themselves.
The phrase "kill themselves" must be set off from the preceding list because it cannot share the verb "are."

3. They’re equipped with smartphones that allow them to collect simple bits of useful information, report threats to the local environment, take photos, and input location coordinates.
The "to" preceding "threats to the local environment" is extraneous because it, and the two other phrases that follow it in the list of four smartphone functions, can share the "to" that precedes the first list item. In addition, "also" is unnecessary.

4. This area is closed on weekends and holidays and for special events.
The phrase "special events" requires its own preposition. Because "holidays" shares a preposition with "weekends," the two words should be connected by a conjunction, and the commas should be omitted.

5. Studies show that dropouts dim not only their own economic future but also that of the communities where they live.
Because the two phrases in this "not only . . . but also" construction (which lacks the required word "also") share a verb, the verb should precede "not only." Also, the comma is unnecessary. (The final phrase could also be simplified: "Studies show that dropouts dim not only their own economic future but also that of their community.")
