More boys speak up in live zoom classes than girls, and more girls communicate through messaging or email than boys.

Some boys are more outgoing, and they express their ideas openly. When they think of something to say, they unmute themselves and open their mouth to say it. Maybe boys also tend to forget their questions, so they ask it in the moment in order not to forget it. Or perhaps they want to know the answer to a question as fast as possible.

Some girls may tend to be more shy, so they wait after class to email the teacher privately. They may not want everyone in the class listening in on their questions/comments. They also might be more conscious and thoughtful. When a question arises in their mind, they let it fully form before communicating it. Emailing the teacher would allow them to think about their questions before they actually send it. They might be wary of saying something that they will regret saying, so emailing will also allow them to revise their wording so they don’t make a mistake.

These may be some reasons why boys generally talk more in zoom classes and girls generally email more. This doesn’t apply to everyone, but I generally would email a teacher rather than talk in a zoom class.
