Answer 1

Explanation:

Alex brushes his teeth twice a day..

Answer 2

The verb is 'brush'.

Actually, the word 'brush' is a noun as well as verb. While taking about a 'brush' ( a toothbrush, paintbrush or any kind of brush ) it is considered as a noun and while talking about the action ( brushing your teeth, brushing your skills, etc ) it becomes a verb. Here, in the given sentence, it acts as a verb, though.
