She provides examples of things that are invisible

Explanation:

There's more to invisibility than what doesn't meet the eye. All sorts of things are invisible to us, for different reasons. Some, like atoms, are too tiny to see. Others, like a black cat on a dark night, aren't lit brightly enough.

The author provides examples of things that are invisible.

there is 2 main differences, basically which are the users and the market. the other difference is the kind of content

people who use tik tok are mainly people from east asia, kind of like the app douyin. musically, on the other hand, are used by people from america or european countries.

while tik tok videos show things like daily life videos, comedy, or just funny videos, musically are like people mimicking songs with their own actions, 'imitate' singers and video clips.

hope this !
